2. Reason / B. Laws of Thought / 6. Ockham's Razor
Supposing many principles is superfluous if a few will do it [Aquinas]
     Full Idea: It is superfluous to suppose that what can be accounted for by a few principles has been produced by many.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob2)
     A reaction: Notice that this is 'superfluous' rather than 'wrong'. But ten people can lift a piano which could have been lifted by eight. Note that this is 150 years before Ockham.
3. Truth / A. Truth Problems / 1. Truth
Truth is universal, but knowledge of it is not [Aquinas]
     Full Idea: The truth is the same for all, but is not equally known to all.
     From: Thomas Aquinas (Summa Theologicae [1265], I-II Q94 4)
     A reaction: Amazing how many modern thinkers fail to grasp this simple distinction. However, the truth is not quite the same for all if diverse persons are expressing a single truth with different concepts and languages. The word 'facts' is helpful here.
Types of lying: Speak lies, intend lies, intend deception, aim at deceptive goal? [Aquinas, by Tuckness/Wolf]
     Full Idea: Lying can involve (1) speaking false words, (2) the intention to speak false words, (3) the intention of bringing about deception, and (4) the ultimate goal of one's deception.
     From: report of Thomas Aquinas (Summa Theologicae [1265], Q110) by Tuckness,A/Wolf,C - This is Political Philosophy 10 'Lying'
     A reaction: It's a start, but much more is needed to clarify lying. Irony is an obvious problem with (1).
3. Truth / A. Truth Problems / 9. Rejecting Truth
If the existence of truth is denied, the 'Truth does not exist' must be true! [Aquinas]
     Full Idea: Whoever denies the existence of truth grants that truth does not exist: and if truth does not exist, then the proposition 'Truth does not exist' is true: and if there is anything true, there must be truth.
     From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3)
     A reaction: A classic example of turning the tables, also applicable to anyone who firmly denies knowledge, or that words are meaningful, or says that meaning needs verification. However, one measily truth is not much consolation.
5. Theory of Logic / B. Logical Consequence / 1. Logical Consequence
If a syllogism admits one absurdity, others must follow [Aquinas]
     Full Idea: In syllogistic arguments, granted one absurdity, others must follow too.
     From: Thomas Aquinas (Summa Theologicae [1265], I-II Q19 6)
     A reaction: This asserts the necessity of logical consequence, which he derives from Aristotle.
5. Theory of Logic / F. Referring in Logic / 1. Naming / d. Singular terms
Mental files are the counterparts of singular terms [Recanati]
     Full Idea: Mental files are the mental counterparts of singular terms.
     From: François Recanati (Mental Files [2012], 3.3)
     A reaction: A thoroughly satisfactory theory. We can build up a picture of filing merging, duplication, ambiguity, error etc. Eventually neuroscience will map the whole system, and we will have cracked it.
7. Existence / A. Nature of Existence / 3. Being / g. Particular being
Being implies distinctness, which implies division, unity, and multitude [Aquinas]
     Full Idea: What first comes to mind is being; secondly, that this being is not that being, and thus we apprehend division as a consequence; thirdly, comes the notion of one; fourthly the notion of multitude.
     From: Thomas Aquinas (Summa Theologicae [1265], I Q11 ar2 ad4), quoted by Roderick Chisholm - Person and Object 1.5
     A reaction: This is one of the best things I have read on 'being'. It is the Aristotelian recognition that we can only study being by studying identity, and that this leads on to wider metaphysics. Other approaches to being are dead ends.
7. Existence / D. Theories of Reality / 5. Naturalism
Non-human things are explicable naturally, and voluntary things by the will, so God is not needed [Aquinas]
     Full Idea: All natural things can be reduced to one principle, which is nature; and all voluntary things can be reduced to one principle, which is human reason, or will. Therefore God does not exist.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob2)
     A reaction: Not, of course, the opinion of Aquinas. So the possibility of naturalism (assuming the human will can be further reduced to nature) was a clear option in the thirteenth century. In reply Aquinas cites his Fifth Way.
9. Objects / C. Structure of Objects / 2. Hylomorphism / d. Form as unifier
Humans only have a single substantial form, which contains the others and acts for them [Aquinas]
     Full Idea: A human being has no substantial form other than the intellective soul alone, and it contains the sensitive and nutritive souls, and all lower forms, and it alone brings about whatever it is that less perfect forms bring about in other things.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia Q76 4c), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 25.1
     A reaction: He says brutes and plants also have a single soul. Pasnau says this is Aquinas's most distinctive doctrine, because other thinkers postulate a whole hierarchy of substantial forms.
9. Objects / F. Identity among Objects / 6. Identity between Objects
Identity statements are informative if they link separate mental files [Recanati]
     Full Idea: An identity statement 'A=B' is informative to the extent that the terms 'A' and 'B' are associated with distinct mental files.
     From: François Recanati (Mental Files [2012], 4.1)
     A reaction: Hence the information in 'Scott is the author of 'Waverley'' is information about what is in your mind, not what is happening in Scotland. This is Recanati's solution to one of Frege's classic puzzles. 'Morning Star' and 'Evening Star' files. Nice.
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
The conclusions of speculative reason about necessities are certain [Aquinas]
     Full Idea: Since the speculative reason is concerned chiefly with necessary things, which cannot be otherwise than they are, its proper conclusions, like the universal principles, contain the truth without fail.
     From: Thomas Aquinas (Summa Theologicae [1265], I-II Q94 4)
     A reaction: This seems over-confident, and to confuse the facts with our knowledge of the facts. Simple arithmetic may seem certain, but long and intricate proofs are always a little uncertain.
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / b. Direct realism
A knowing being possesses a further reality, the 'presence' of the thing known [Aquinas]
     Full Idea: Knowing beings are differentiated from non-knowing beings by this: non-knowing beings have only their own reality, but knowing beings are capable of possessing also the reality of something else, ...a presence of the thing known produced by this thing.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,q.Q14,art 1)
     A reaction: [Quoted by Ryan Meade in a talk at Pigotts] A famous and much discussed remark. Aquinas was a direct realist about perception, so this presence seems to be the thing itself, rather than a 'representation'.
There is a continuum from acquaintance to description in knowledge, depending on the link [Recanati]
     Full Idea: It is not too difficult to imagine a continuum of cases between straightforward instances of knowledge by acquaintance and straightforward instances of knowledge by description, with more or less tenuous informational links to the referent.
     From: François Recanati (Mental Files [2012], 12.2)
12. Knowledge Sources / A. A Priori Knowledge / 2. Self-Evidence
Some things are self-evident to us; others are only self-evident in themselves [Aquinas]
     Full Idea: A thing can be self-evident in either of two ways: on the one hand, self-evident in itself, though not to us; on the other hand, self-evident in itself, and to us.
     From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3)
     A reaction: A clear distinction, which is hard to deny, though there are lots of borderline cases. Self-evident to genius, and self-evident to future genius. Self-evident to almost everyone. Goldbach's Conjecture may be self-evident but unknowable.
12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic
A proposition is self-evident if the predicate is included in the essence of the subject [Aquinas]
     Full Idea: A proposition is self-evident because the predicate is included in the essence of the subject. E.g. Man is an animal, because animal is included in the essence of man.
     From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3)
     A reaction: Aquinas focuses on the essence of the subject, where Kant embraces the whole concept of the subject. Is it self-evident that we are genetically related to apes? Yes, to a geneticiist. Is that part of human essence? No. So Kant wins.
12. Knowledge Sources / C. Rationalism / 1. Rationalism
Sensation prepares the way for intellectual knowledge, which needs the virtues of reason [Aquinas]
     Full Idea: Knowledge of truth is not consummated in the sensitive powers of apprehension, for these prepare the way to intellectual knowledge. And therefore in these powers there are none of the virtues by which we know truth; these are in the intellect or reason.
     From: Thomas Aquinas (Summa Theologicae [1265], I-II Q56 a5 obj3), quoted by Linda Trinkaus Zagzebski - Virtues of the Mind III 2.2
     A reaction: A gem of a quotation for Zagzebski's thesis, that knowledge is defined in terms of the intellectual virtues. The only virtues of perception are in focusing and paying attention to features. Good eyesight is a biological 'virtue', I suppose.
15. Nature of Minds / C. Capacities of Minds / 1. Faculties
Sensations are transmitted to 'internal senses' in the brain, chiefly to 'phantasia' and 'imagination' [Aquinas, by Kretzmann/Stump]
     Full Idea: Sensory species received in external senses are transmitted to 'internal senses', organs located in the brain. The most important of these for cognition are 'phantasia' and 'imagination' (part of phantasia), which produce and preserve 'phantasms'.
     From: report of Thomas Aquinas (Summa Theologicae [1265]) by Kretzmann/Stump - Aquinas, Thomas 11
     A reaction: This seems to make Aquinas a representative realist. I add this to my portfolio of philosophical faculties - those required by philosophy, rather than by psychology or neuroscience.
15. Nature of Minds / C. Capacities of Minds / 2. Imagination
Mental activity combines what we sense with imagination of what is not present [Aquinas]
     Full Idea: Mental activity combines two activities which in the senses are distinct: exterior perception in which we are simply affected by what we sense, and interior imagination in which we create images of things that are not, and never have been present.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.2)
     A reaction: Geach cites this thought to show that he is anti-abstractionist, since mind creates images, and these can arise from things which have not been experienced. Any defence of abstractionism must allow an active power to imagination.
15. Nature of Minds / C. Capacities of Minds / 3. Abstraction by mind
Abstracting A from B generates truth, as long as the connection is not denied [Aquinas]
     Full Idea: Abstacting A from B can mean denying A's connection with B, or simply thinking A without thinking B. Abstracting what in reality is connected generates falsehood if done the first way, but not if done the second.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1)
     A reaction: Despite Geach's denials, this seems to make Aquinas a classic abstractionist. He goes on to distinguish two sorts of abstraction, but he certainly thinks of abstraction from sense experience as a revelation about the nature of reality.
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
We understand the general nature of things by ignoring individual peculiarities [Aquinas]
     Full Idea: If we think what defines a stone, man or horse, without thinking of any individual peculiarities it may have, this is precisely what we do when we abstract the general nature of what we understand from any particular way in which we imagine it.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1)
     A reaction: This may not be simple abstraction from sense experience, since there would obviously be a threatened circularity in the process. Do you need to know the essential definition first, in order to discard the individual peculiarities?
The mind abstracts generalities from images, but also uses images for understanding [Aquinas]
     Full Idea: Our mind both abstracts the species from images when it attends to the general nature of things, and understand the species in the images when it has recourse to the images in order to understand the things whose species it has abstracted.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1)
     A reaction: Geach claims that the second half of this idea means that Aquinas is not an abstractionist, but he seems to be explictly abstractionist about the way in which we create higher level concepts from lower ones.
Very general ideas (being, oneness, potentiality) can be abstracted from thought matter in general [Aquinas]
     Full Idea: There are even things we can abstract from thought matter in general, things like being and oneness and potentiality and realization.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1)
     A reaction: The Aristotelian 'potentiality' means possibility, which means that modality is understood by abstraction. Aquinas seems to have four levels: particular perceived, general perceived, particular thought, and general thought. This is the highest level.
Particular instances come first, and (pace Plato) generalisations are abstracted from them [Aquinas]
     Full Idea: The generality attaching to a nature - its relatedness to many particular instances - results from abstraction, so in this sense a generalized nature presupposes its instances, and does not, as Plato thought, precede them.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.2)
     A reaction: This seems to be a quite explicit endorsement of abstractionism by Aquinas, despite all Geach's assertions to the contrary.
Species are abstracted from appearances by ignoring individual conditions [Aquinas]
     Full Idea: The agent intellect abstracts intelligible species from phantasms insofar as through the power of the agent intellect we can take into our consideration the natures of the species without the individual conditions.
     From: Thomas Aquinas (Summa Theologicae [1265], Q85 Ad4)
     A reaction: There might be a threatened circularity here, in trying to decide which features to ignore and which to retain. If we saw a hundred horses with a white nose blaze, we still wouldn't be sure that this was essential to a horse. Innate notions of species??
16. Persons / F. Free Will / 1. Nature of Free Will
Aquinas attributes freedom to decisions and judgements, and not to the will alone [Aquinas, by Kretzmann/Stump]
     Full Idea: Aquinas conceives of freedom as free decision or judgement, which cannot be attributed to the will alone.
     From: report of Thomas Aquinas (Summa Theologicae [1265]) by Kretzmann/Stump - Aquinas, Thomas 12
     A reaction: This idea might improve the free will debate considerably, because it is not clear what sort of thing a 'will' is, and it is not clear how an entity can be 'free' in isolation, by its intrinsic nature. Isn't all freedom contextual?
17. Mind and Body / A. Mind-Body Dualism / 1. Dualism
The human intellectual soul is an incorporeal, subsistent principle [Aquinas]
     Full Idea: It is necessary to say that that which is the principle of intellective activity, what we call the soul of a human being, is an incorporeal, subsistent principle.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia.Q75 2c), quoted by Kretzmann/Stump - Aquinas, Thomas 10
     A reaction: Note 'subsistent' rather than 'existent' (capable of independence?). This identifies the immortal soul with the conscious mind. 'Principle' is an odd word, presumably with roots in Aristotle. It seems to be an Aristotelian 'form' [morphe].
18. Thought / A. Modes of Thought / 6. Judgement / a. Nature of Judgement
First grasp what it is, then its essential features; judgement is their compounding and division [Aquinas]
     Full Idea: The intellect first apprehends the quiddity of a thing. ...Then it acquires the properties, accidents and dispositions associated with the thing's essence. It must proceed from one compounding or dividing of aspects to another, which is reasoning.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia.Q85 5c), quoted by Kretzmann/Stump - Aquinas, Thomas 11
     A reaction: [compressed] Tracking the process of acquiring knowledge of a thing (rather than necessary and sufficient conditions for full knowledge) is closer to Quine's naturalised epistemology than to the standard analytic approach to the concept of knowledge.
18. Thought / A. Modes of Thought / 9. Indexical Thought
Indexicals apply to singular thought, and mental files have essentially indexical features [Recanati]
     Full Idea: I defend the applicability of the indexical model to singular thought, and to mental files qua vehicles of singular thought. Mental files, I will argue, possess the essential features of indexicals.
     From: François Recanati (Mental Files [2012], 05.1)
     A reaction: I love mental files, but am now (thanks to Cappelen and Dever) deeply averse to giving great significance to indexicals. A revised account of files will be needed.
Indexicality is closely related to singularity, exploiting our direct relations with things [Recanati]
     Full Idea: Singularity and indexicality are closely related: for indexicals systematically exploit the contextual relations in which we stand to what we talk about.
     From: François Recanati (Mental Files [2012], 2.2)
     A reaction: Recanati builds a nice case that we may only have an ontology of singular objects because we conceptualise and refer to things in a particular way. He denies the ontology, but that's the bit that interests me.
18. Thought / B. Mechanics of Thought / 5. Mental Files
Files can be confused, if two files correctly have a single name, or one file has two names [Recanati]
     Full Idea: Paderewski cases are cases in which a subject associates two distinct files with a single name. Inverse Paderewski cases are cases in which there are two names but the subject associates them with a single file.
     From: François Recanati (Mental Files [2012], 10.1)
     A reaction: In the inverse there are two people with the same name, and someone thinks they are one person (with their combined virtues and vices). E.g. Einstein the famous physicist, and Einstein the famous musicologist. What a man!
Encylopedic files have further epistemic links, beyond the basic one [Recanati]
     Full Idea: The reference of a file is the object to which the subject stands in the relevant epistemic relation. In the case of encylopedic entries there is an arbitrary number of distinct relations. The file grows new links in an opportunistic manner.
     From: François Recanati (Mental Files [2012], 11.3)
     A reaction: I'm not convinced by Recanati's claim that encylopedic files are a distinct type. My files seem to grow these opportunistic links right from their inception. All files seem to have that feature. A file could have four links at its moment of launching.
Singular thoughts need a mental file, and an acquaintance relation from file to object [Recanati]
     Full Idea: The mental file framework rests on two principles: that the subject cannot entertain a singular thought about an object without possessing and exercising a mental file about it, and that this requires an acquaintance relation with the object.
     From: François Recanati (Mental Files [2012], 12.3)
     A reaction: I'm puzzled by the case where I design and build a completely new object. I seem to assemble a file, and only bestow singularity on it towards the end. Or the singularity can just be a placeholder, referred to as 'something'. […see p.158]
Expected acquaintance can create a thought-vehicle file, but without singular content [Recanati]
     Full Idea: On my view, actual acquaintance is not necessary to open a mental file; expected acquaintance will suffice; yet opening a mental file itself is not sufficient to entertain a singular thought-content. It only enables a thought-vehicle.
     From: François Recanati (Mental Files [2012], 13.1)
     A reaction: I'm not clear why I can't create a file with no expectation at all of acquaintance, as in a fictional case. Depends what 'acquaintance' means. Recanati longs for precise distinctions where they may not be available.
An 'indexed' file marks a file which simulates the mental file of some other person [Recanati]
     Full Idea: Files function metarepresentationally if they serve to represent how other subjects think about objects in the world. ..An 'indexed' file has an index referring to the other subject whose files the indexed file stands for or simulates.
     From: François Recanati (Mental Files [2012], 14.1)
     A reaction: Presumably there is an implicit index on all files, which says in a conversation whether my interlocutor does or does not hold the same file-type as me. Recanati wants many 'types' of files, but I suspect there is just one file type.
Reference by mental files is Millian, in emphasising acquaintance, rather than satisfaction [Recanati]
     Full Idea: The mental file account preserves the original, Millian inspiration of direct reference theories in giving pride of place to acquaintance relations and downplaying satisfaction factors.
     From: François Recanati (Mental Files [2012], 17.3)
     A reaction: I find this a very satisfying picture, in which reference links to the simple label of a file (which could be a number), and not to its contents. There are tricky cases of non-existents, fictional entities and purely possible entities to consider.
The reference of a file is fixed by what it relates to, not the information it contains [Recanati]
     Full Idea: What files refer to is not determined by properties which the subject takes the referent to have (information, or misinformation, in the file), but through the relations on which the files are based.
     From: François Recanati (Mental Files [2012], 3.3)
     A reaction: Maybe. 'Lot 22'. I can build up a hypothetical file by saying 'Imagine an animal which is F, G, H…', and build a reference that relates to nothing. Maybe Recanati overestimates the role of his 'epistemically rewarding' relations in file creation.
A mental file treats all of its contents as concerning one object [Recanati]
     Full Idea: The role of a mental file is precisely to treat all the information as if it concerned one and the same object, from which it derives.
     From: François Recanati (Mental Files [2012], 4.1)
     A reaction: Recanati's book focuses entirely on singular objects, but we presumably have files for properties, generalisation, groups etc. Can they only be thought about if they are reified? Maybe.
There are transient 'demonstrative' files, habitual 'recognitional' files, cumulative 'encyclopedic' files [Recanati]
     Full Idea: A 'demonstrative' file only exists during the demonstrative relation to something; …a 'recognitional' file is based on 'familiarity' (a disposition to recognise); …an 'encylopedic' file contains all the information on something, however it is gained.
     From: François Recanati (Mental Files [2012], 6.1-3)
     A reaction: [picked as samples of his taxonomy, pp.70-73] I'm OK with this as long as he doesn't think the categories are sharply separated. I'm inclined to think of files as a single type, drifting in and out of different of modes.
Files are hierarchical: proto-files, then first-order, then higher-order encyclopedic [Recanati]
     Full Idea: There is a hierarchy of files. Proto-files are the most basic; conceptual files are generated from them. First-order ones are more basic, as the higher-order encylopedic entries presuppose them.
     From: François Recanati (Mental Files [2012], 6.3)
     A reaction: This hierarchy might fit into a decent account of categories, if a plausible one could be found. A good prospect for exploring categories would be to start with mental file-types, and work outwards through their relations.
A file has a 'nucleus' through its relation to the object, and a 'periphery' of links to other files [Recanati]
     Full Idea: I take a file to have a dual structure, with a 'nucleus' of the file consisting of information derived through the relevant epistemically rewarding relation, while the 'periphery' consists of information derived through linking with other files.
     From: François Recanati (Mental Files [2012], 8.3)
     A reaction: This sounds strikingly like essentialism to me, though what constitutes the essence is different from the usual explanatory basics. The link, though, is in the causal connection. If we naturally 'essentialise', that will control file-formation.
18. Thought / C. Content / 1. Content
The content of thought is what is required to understand it (which involves hearers) [Recanati]
     Full Idea: As Evans emphasises, what matters when we want to individuate semantic content is what would count as a proper understanding of an utterance; but 'understanding' defines the task of the hearer.
     From: François Recanati (Mental Files [2012], 16.2)
     A reaction: [cites Evans 1982: 92, 143n, 171] I like to place (following Aristotle) understanding at the centre of all of philosophy, so this seems to me an appealing idea. It makes misunderstandings interesting.
18. Thought / D. Concepts / 1. Concepts / a. Nature of concepts
Mental files are individual concepts (thought constituents) [Recanati]
     Full Idea: I want mental files (properly speaking) to serve as individual concepts, i.e. thought constituents.
     From: François Recanati (Mental Files [2012], 5.3)
     A reaction: This is why the concept of mental files is so neat - it gives you a theory of reference and a theory of concepts. I love the files approach because it precisely fits my own introspective experiences. Hope I'm not odd in that way.
18. Thought / E. Abstraction / 1. Abstract Thought
We abstract forms from appearances, and acquire knowledge of immaterial things [Aquinas]
     Full Idea: To cognize that which is in individual matter, not as it is in such matter, is to abstract the form from the individual matter that the phantasms represents. Thus we come to a degree of cognition of immaterial things.
     From: Thomas Aquinas (Summa Theologicae [1265], Q85 1 Reply)
     A reaction: This offers abstraction as a kind of inference to best explanation which takes us beyond immediate empirical experience to what is behind it. Aquinas thinks the concepts and explanation are spiritual, but they may be generalities and essences.
Understanding consists entirely of grasping abstracted species [Aquinas]
     Full Idea: Of the thing understood all that is within the actually understanding intellect is the abstracted intelligible species.
     From: Thomas Aquinas (Summa Theologicae [1265], Q85 Art2)
     A reaction: Abstraction is never supposed to be a luxury bolt-on, but is always seen (in this tradition, and presumably in the modern one), as essential to the intellect, and its way of coming to understand the world. Aristotelian definition is behind this idea.
18. Thought / E. Abstraction / 2. Abstracta by Selection
Mathematics can be abstracted from sensible matter, and from individual intelligible matter [Aquinas]
     Full Idea: Intellect can abstract mathematical species from sensible matter, both individual and common. Yet it cannot abstract such species from common intelligible matter, but only from individual intelligible matter.
     From: Thomas Aquinas (Summa Theologicae [1265], Q85 Ad2)
     A reaction: The idea is that common intelligible matter lacks underlying substance, which is where quantity is to be found.
18. Thought / E. Abstraction / 3. Abstracta by Ignoring
Mathematical objects abstract both from perceived matter, and from particular substance [Aquinas]
     Full Idea: Objects of mathematics abstract from perceived matter both in particular and in general, though from thought matter (substance as underlying quality) only in particular and not in general.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1)
     A reaction: This appears to be a thoroughly abstractionist view of the way in which humans create mathematics. Aquinas explicitly denies the Platonic view that the numbers already have abstract existence, awaiting our discovery.
We can just think of an apple's colour, because the apple is not part of the colour's nature [Aquinas]
     Full Idea: The apple is not part of the nature of the colour, and so nothing prevents one from understanding the colour while understanding nothing of the apple.
     From: Thomas Aquinas (Summa Theologicae [1265], Q85 1 Ad 1)
     A reaction: This helps to clarify why the procedure of 'ignoring' features is possible. It suggests that some features might be too entangled with the substance (too essential?) to be thus ignored. I can't think of an example, though. Why not?!
Abstracting either treats something as separate, or thinks of it separately [Aquinas]
     Full Idea: Abstracting takes place in two ways: by composition and division, understanding something to be not in another or to be separated from it; and by a simple and unconditioned consideration, understanding one thing while not considering the other at all.
     From: Thomas Aquinas (Summa Theologicae [1265], Q85 1 Ad 1)
     A reaction: The second way is by 'ignoring', which he says cannot contain error. The first seems to be considering some mode of a thing to be actually separate from the thing, which could clearly be erroneous. Ignoring makes to commitment to a unity.
Numbers and shapes are abstracted by ignoring their sensible qualities [Aquinas]
     Full Idea: Quantities such as numbers and dimensions, and also shapes (which are the limits of quantities) can be considered without their sensible qualities, which is for them to be abstracted from sensible matter.
     From: Thomas Aquinas (Summa Theologicae [1265], Q85 Ad2)
     A reaction: His account relies on underlying substance, which is where quantity is to be found (presumably because a substance is the epitome of a unit).
18. Thought / E. Abstraction / 8. Abstractionism Critique
The mind must produce by its own power an image of the individual species [Aquinas]
     Full Idea: The agent mind must itself turn to images, and produce by its own power in the receptive mind a representation as to species of whatever the images represent as individual.
     From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1)
     A reaction: Unlike much of this section, this sentence supports Geach's claim that Aquinas agrees with him - that the mind creates its concepts, rather than 'abstracting' them from experience.
19. Language / B. Reference / 1. Reference theories
There may be two types of reference in language and thought: descriptive and direct [Recanati]
     Full Idea: A widely held view, originating with Russell, says there are two types of reference (both in language and thought): descriptive reference, and direct reference.
     From: François Recanati (Mental Files [2012], 3.2)
     A reaction: I would rather say is there is just one sort of reference, and as many ways of achieving it as you care to come up with. With that view, most of the problems vanish, as far as I can see. People refer. Sentences are nothing but trouble.
19. Language / B. Reference / 3. Direct Reference / a. Direct reference
In super-direct reference, the referent serves as its own vehicle of reference [Recanati]
     Full Idea: In super-direct reference, the sort of thing Russell was after, there is no mode of presentation: the referent itself serves as its own vehicle, as it were.
     From: François Recanati (Mental Files [2012], 18.2)
     A reaction: To me this is a step too far, because reference is not some physical object like a chair; it is a mental or linguistic phenomenon. Chair's don't refer themselves; it is people who refer.
Direct reference is strong Millian (just a tag) or weak Kaplanian (allowing descriptions as well) [Recanati]
     Full Idea: There are two notions of direct reference, the strong Millian notion (where the expression is like a 'tag' with no satisfaction mechanism), and the weaker Kaplanian notion (where reference is compatible with carrying a descriptive meaning).
     From: François Recanati (Mental Files [2012], 17.3)
     A reaction: I immediately favour the Millian view, which gives a minimal basis for reference, as just a 'peg' (Marcus) to hang things on. I don't take a Millian reference to be the object itself. The concept of a 'tag' or 'label' is key. Mental files have tags.
19. Language / B. Reference / 4. Descriptive Reference / a. Sense and reference
Sense determines reference says same sense/same reference; new reference means new sense [Recanati]
     Full Idea: To say that sense determines reference is to say that the same sense cannot determine distinct referents - any distinction at the level of reference entails a corresponding distinction at the level of sense.
     From: François Recanati (Mental Files [2012], 10.2)
     A reaction: Does 'the sentry at the gate' change its sense when the guard is changed? Yes. 'The sentry at the gate will stop you'. 'The sentry at the gate is my cousin'. De re/de dicto reference. So changes of de re reference seem to change the sense?
We need sense as well as reference, but in a non-descriptive form, and mental files do that [Recanati]
     Full Idea: My view inherits from Frege 'modes of presentation'. Reference is not enough, and sense is needed. …We must make room for non-descriptive modes of presentation, and these are mental files.
     From: François Recanati (Mental Files [2012], 18.1)
     A reaction: [compressed] Recanati aims to avoid the standard Kripkean criticisms of descriptivism, while being able to handle Frege's puzzles. I take Recanati's mental files theory to be the most promising approach.
Sense is a mental file (not its contents); similar files for Cicero and Tully are two senses [Recanati]
     Full Idea: What plays the role of sense is not information in a file, but the file itself. If there are two distinct files, one for 'Cicero' and one for 'Tully', then there are two distinct (non-descriptive) senses, even if the information in both files is the same.
     From: François Recanati (Mental Files [2012], 3.4)
     A reaction: This may be the best idea in Recanati's book. A sense might be a 'way of coming at the information', rather than some set of descriptions.
19. Language / B. Reference / 4. Descriptive Reference / b. Reference by description
Problems with descriptivism are reference by perception, by communications and by indexicals [Recanati]
     Full Idea: Three problems with Frege's idea of descriptions in the head are: reference through perception, reference through communicative chains, and reference through indexicals.
     From: François Recanati (Mental Files [2012], 3.1)
     A reaction: In the end reference has to occur in the head, even if it is social or causal or whatever, so these are not problems that worry me.
Descriptivism says we mentally relate to objects through their properties [Recanati]
     Full Idea: Descriptivism is the view that our mental relation to individual objects goes through properties of those objects. …This is so because our knowledge of objects is mediated by our knowledge of their properties.
     From: François Recanati (Mental Files [2012], 1.1)
     A reaction: The implication is that if you view an object as just a bundle of properties, then you are obliged to hold a descriptive theory of reference. Hence a 'singularist' theory of reference seems to need a primitive notion of an object's identity.
Definite descriptions reveal either a predicate (attributive use) or the file it belongs in (referential) [Recanati]
     Full Idea: A definite description may contribute either the singular predicate it encodes (attributive use) or the mental file to what that predicate belongs (referential use).
     From: François Recanati (Mental Files [2012], 17.1)
     A reaction: This nicely explains Donnellan's distinction in terms of mental files. 'Green' may refer in a shop, but isn't much use in a wood. What to make of 'He's a bit of a Bismark'?
A rigid definite description can be attributive, not referential: 'the actual F, whoever he is….' [Recanati]
     Full Idea: A rigid use of a definite description need not be referential: it may be attributive. Thus I may say: 'The actual F, whoever he is, is G'.
     From: François Recanati (Mental Files [2012], 2.2)
     A reaction: Recanati offers this as a criticism of the attempted 2-D solution to descriptivist accounts of singularity. The singularity is not strong enough, he says.
Singularity cannot be described, and it needs actual world relations [Recanati]
     Full Idea: As Peirce insisted, singularity as such cannot be described, it can only be given through actual world relations.
     From: François Recanati (Mental Files [2012], 2.2)
     A reaction: [Peirce - Exact Logic, Papers 3, 1967, §419] This is the key idea for Recanati's case for basing our grasp of singular things on their relation to a mental file.
19. Language / C. Assigning Meanings / 5. Fregean Semantics
Fregean modes of presentation can be understood as mental files [Recanati]
     Full Idea: A mental file plays the role which Fregean theory assigns to modes of presentation.
     From: François Recanati (Mental Files [2012], 17.1)
     A reaction: I'm a fan of mental files, and this is a nice pointer to how the useful Fregean insights can be written in a way better grounded in brain operations. Rewriting Frege in neuroscience terms is a nice project for someone.
19. Language / C. Assigning Meanings / 9. Indexical Semantics
If two people think 'I am tired', they think the same thing, and they think different things [Recanati]
     Full Idea: If you and I think 'I am tired', there is a sense in which we think the same thing, and another sense in which we think different things.
     From: François Recanati (Mental Files [2012], 18.1)
     A reaction: This is a very nice simple account of the semantic distinctiveness of indexicals, which obviously requires a 'two-tiered framework'. He cites Kaplan and Perry as background.
Indexicals (like mental files) determine their reference relationally, not by satisfaction [Recanati]
     Full Idea: The class of indexicals have the same property as mental files, that their reference is determined relationally rather than satisfactionally.
     From: François Recanati (Mental Files [2012], 5.1)
     A reaction: Recanati is building an account of reference through mental files. This idea may be the clearest point I have yet encountered about indexicals, showing why they are of particular interest to philosophers.
Indexical don't refer; only their tokens do [Recanati]
     Full Idea: Indexicals do not refer; only tokens of an indexical refer
     From: François Recanati (Mental Files [2012], 5.1)
     A reaction: Thus 'Thurs 23rd March 2013' refers, but 'now' doesn't, unless someone produces an utterance of it. This is why indexicals are sometimes called 'token-reflexives'.
19. Language / C. Assigning Meanings / 10. Two-Dimensional Semantics
In 2-D semantics, reference is determined, then singularity by the truth of a predication [Recanati]
     Full Idea: In the two-dimensional framework, what characterises the singular case is the fact that truth-evaluation (of possessing of the reference-fixing property) takes place at a later stage than reference determination.
     From: François Recanati (Mental Files [2012], 2.1)
     A reaction: This sounds psychologically plausible, which is a big (and unfashionable) plus for me. 1) what are we talking about? 2) what are we saying about it, 3) is it true?
Two-D semantics is said to help descriptivism of reference deal with singular objects [Recanati]
     Full Idea: Descriptivism has trouble catching the singularity of objects, construing them as only directly about properties. …To get the truth-conditions right, it is claimed, the descriptivist only as to go two-dimensional.
     From: François Recanati (Mental Files [2012], 2.1)
     A reaction: I suspect that the descriptivist only has a problem here because context is being ignored. 'That man on the beach' can quickly be made uniquely singular after a brief chat.
19. Language / D. Propositions / 3. Concrete Propositions
Russellian propositions are better than Fregean thoughts, by being constant through communication [Recanati]
     Full Idea: The Russellian notion of a proposition is arguably a better candidate for the status of semantic content than the Fregean notion of a thought. For the proposition remains constant from one person to the next.
     From: François Recanati (Mental Files [2012], 16.2)
     A reaction: A good point, though I rebel against Russellian propositions because they are too much out in the world, and propositions strike me as features of minds. We need to keep propositions separate from facts.
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
The will is the rational appetite [Aquinas]
     Full Idea: The will is the rational appetite.
     From: Thomas Aquinas (Summa Theologicae [1265], II-II Q58 4)
     A reaction: Defining the will in terms of reason sounds more like an Enlightenment optimist than a medieval theologian. I suspect that for him it is tautological the reason is involved, if only the reason can make decisions. Hobbes prefers to ruling appetite.
21. Aesthetics / C. Artistic Issues / 7. Art and Morality
Musical performance can reveal a range of virtues [Damon of Ath.]
     Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice.
     From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where?
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
For humans good is accordance with reason, and bad is contrary to reason [Aquinas]
     Full Idea: A human being's good is existing in accordance with reason, while what is bad for a human being is whatever is contrary to reason.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia IIae.Q18.5c), quoted by Kretzmann/Stump - Aquinas, Thomas 13
     A reaction: For anyone who thought Kant invented the idea that morality derives from reason. This idea of Aquinas is a fairly precise echo of the stoic view (which influenced Kant). Is there a circularity? Is it irrational because bad, or bad because irrational?
22. Metaethics / B. Value / 1. Nature of Value / e. Means and ends
We must know the end, know that it is the end, and know how to attain it [Aquinas]
     Full Idea: Perfect knowledge of the end consists in not only apprehending the thing which is the end but also knowing it under the aspect of the end and the relation of the means to that end.
     From: Thomas Aquinas (Summa Theologicae [1265], II-I.Q132), quoted by Philippa Foot - Natural Goodness 4
     A reaction: We don't talk much now about 'perfect' knowledge of something, but I suppose this is the necessary and sufficient conditions. If you complete the checklist, your knowledge should be perfect (if the list is right).
23. Ethics / C. Virtue Theory / 1. Virtue Theory / b. Basis of virtue
All acts of virtue relate to justice, which is directed towards the common good [Aquinas]
     Full Idea: The good of any virtue …is referable to the common good, to which justice directs, so that all acts of virtue can pertain to justice insofar as it directs man to the common good.
     From: Thomas Aquinas (Summa Theologicae [1265], II-II Q58 5)
     A reaction: Michael Sandel has recently lamented to fading of the concept of 'the common good' from our moral and political life. In which case this thought of Aquinas takes on great importance. I certainly like it. It seems to apply to courage, for example.
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / d. Teaching virtue
Aquinas wanted, not to escape desire, but to transform it for moral ends [Aquinas, by MacIntyre]
     Full Idea: The Aristotelianism of Thomas Aquinas (unlike St Augustine's Platonism) is not concerned with escaping from the snares of the world and of desire, but with transforming desire for moral ends.
     From: report of Thomas Aquinas (Summa Theologicae [1265]) by Alasdair MacIntyre - A Short History of Ethics Ch.9
     A reaction: This is very close to Aristotle himself, for whom education of the feelings (into good habits, and then true virtues) was central. Education of feelings should be central to all education (though young psychopaths may show resistance).
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / i. Absolute virtues
Legal justice is supreme, because it directs the other virtues to the common good [Aquinas]
     Full Idea: There must be one supreme virtue essentially distinct from every other virtue, which directs all the virtues to the common good, and this virtue is legal justice.
     From: Thomas Aquinas (Summa Theologicae [1265], II-II Q58 6)
     A reaction: This concept of legal justice is underpinned, for Aquinas, by the concept of natural law, which has divine backing. Positive law could hardly fulfil such a major role, given that it could be corrupt.
23. Ethics / C. Virtue Theory / 3. Virtues / b. Temperance
Temperance prevents our passions from acting against reason [Aquinas]
     Full Idea: The passions may incite us to something against reason, and so we need a curb, which we name 'temperance'.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia 2ae Q61 a.3), quoted by Philippa Foot - Virtues and Vices II
     A reaction: I am increasingly unclear what 'reason' means in contexts like these. It seems to mean no more than the awareness of greater goods than the indulgence of passion. Without that awareness, high intelligence couldn't produce temperance.
23. Ethics / C. Virtue Theory / 3. Virtues / c. Justice
Justice directs our relations with others, because it denotes a kind of equality [Aquinas]
     Full Idea: It is proper to justice, as compared with the other virtues, to direct man in his relations with others, because it denotes a kind of equality, as its very name implies; indeed we are wont to say that things are 'adjusted' when they are made equal.
     From: Thomas Aquinas (Summa Theologicae [1265], II-II Q57 1)
     A reaction: Even if you say justice is giving people what they deserve, rather than mere equality, they must still be equal in receiving like for like. Legal justice implies equality before the law (except for monarchs?).
25. Social Practice / D. Justice / 1. Basis of justice
People differ in their social degrees, and a particular type of right applies to each [Aquinas]
     Full Idea: There are many differences of degrees among men, for instance, some are soldiers, some are priests, some are princes. Therefore some special kind of right should be alloted to them.
     From: Thomas Aquinas (Summa Theologicae [1265], II-II Q57 4)
     A reaction: An objection (3), but Aquinas endorses it in his reply. In 58.10 he says striking a prince is worse that striking a commoner. The shift to the idea that everyone is supposed to be equal before the law has been slow, and we are not quite there yet.
25. Social Practice / D. Justice / 2. The Law / c. Natural law
Natural law is a rational creature's participation in eternal law [Aquinas]
     Full Idea: It is evident that the natural law is nothing else than the rational creature's participation of the eternal law.
     From: Thomas Aquinas (Summa Theologicae [1265], I-II Q91 2)
     A reaction: It is not enough merely that God decrees eternal laws. It is also necessary for us to use reason in order to participate. I'm not sure what reasoning process is involved.
Tyrannical laws are irrational, and so not really laws [Aquinas]
     Full Idea: A tyrannical law, since it is not in accord with reason, is not unconditionally a law, but is rather a perversion of law.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia IIae.Q92.1, ad 4), quoted by Kretzmann/Stump - Aquinas, Thomas 13
     A reaction: Only a belief in natural law can give a basis for such a claim. Positivists will say a tyrannical law is unconditionally a law like any other, but a bad one.
Right and wrong actions pertain to natural law, as perceived by practical reason [Aquinas]
     Full Idea: All things to be done or to be avoided pertain to the precepts of natural law, which practical reasoning apprehends naturally as being human goods.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia IIae.Q94.2c), quoted by Kretzmann/Stump - Aquinas, Thomas 13
     A reaction: No mention of God, but you feel the divine presence in the background. He also cites 'eternal law'. No coincidence that the atheist Hobbes rejected natural law. Personally I would offer an atheistic defence of natural law, based on human nature.
25. Social Practice / E. Policies / 1. War / a. Just wars
For Aquinas a war must be in a just cause, have proper authority, and aim at good [Aquinas, by Grayling]
     Full Idea: Aquinas argued that on three conditions war can be justified: first, that there is a just cause; second, that it is begun on proper authority; and third, that it is waged with right intention, for 'the advancement of good, or the avoidance of evil'.
     From: report of Thomas Aquinas (Summa Theologicae [1265], II) by A.C. Grayling - Among the Dead Cities Ch.6
     A reaction: But see also Idea 7292. Nowadays we are rightly suspicious of all three conditions. Evil people seem to think their cause is just; authority has often been seized by violence, or is being abused; and people seem confused about what is good or evil.
25. Social Practice / F. Life Issues / 3. Abortion
Aquinas says a fertilized egg is not human, and has no immortal soul [Aquinas, by Martin/Barresi]
     Full Idea: In Aquinas's view the fertilized egg is not, either at the moment of conception or for quite a while afterwards, endowed with an immortal soul. In fact, technically speaking, it is not even human.
     From: report of Thomas Aquinas (Summa Theologicae [1265]) by R Martin / J Barresi - Introduction to 'Personal Identity' p.20
     A reaction: It is pointed at that therefore Aquinas does not give good support for modern Catholic views on abortion. There is certainly no reason why a human zygote should be ensouled from the start, as God may do this whenever He wishes.
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / c. Matter as extension
Bodies are three-dimensional substances [Aquinas]
     Full Idea: Bodies are those substances in which one finds three dimensions.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia Q18.2c), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 16.2
     A reaction: Pasnau points out that this extensional view of physical bodies was a commonplace long before Descartes. Presumably there are also non-dimensional substances (such as angels?).
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
Divine law commands some things because they are good, while others are good because commanded [Aquinas]
     Full Idea: The divine law commands certain things because they are good and forbids others because they are evil, while others are good because they are prescribed, and others evil because they are forbidden.
     From: Thomas Aquinas (Summa Theologicae [1265], II-II Q57 2)
     A reaction: This is a fifty-fifty response to the Euthyphro dilemma, but it seems to leave the theological puzzle of the source of the goodness which is prescribed because it is in fact good.
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
We can't know God's essence, so his existence can't be self-evident for us [Aquinas]
     Full Idea: Because we do not know the essence of God, the proposition 'God exists' is not self-evident to us, but needs to be demonstrated by things that are more known to us.
     From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3)
     A reaction: Depends on his definition of self-evidence (Idea 21250), which needs knowledge of the essence of the subject. Anselm required 'understanding' of the concept. One might understand the existence criteria without knowing the whole essence. Anselm wins.
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
If you assume that there must be a necessary being, you can't say which being has this quality [Kant on Aquinas]
     Full Idea: To those who assume the existence of a necessary being, and would only know which among all things had to be regarded as such a thing, one could not answer: This thing here is the necessary being
     From: comment on Thomas Aquinas (Summa Theologicae [1265]) by Immanuel Kant - Critique of Pure Reason A612/B640
     A reaction: See Aquinas in Idea 1431. Kant makes a nice point. You might turn out to be the necessary being? How could you tell? You only know that there must be one lurking somewhere. I could be a slug. Aquinas makes a huge leap to God.
Way 1: the infinite chain of potential-to-actual movement has to have a first mover [Aquinas]
     Full Idea: A thing can only be reduced from potentiality to actuality by something actual. A thing can never be in actuality and potentiality in the same respect. So what is moved must be moved by another. But this cannot go on to infinity, with no first mover.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply)
     A reaction: [compressed] This relies on the Aristotelian ideas of potentiality and actuality. We might talk about things moving, but lacking the 'power' to move. This is almost identical to Plato in 'The Laws' (which I guess Aquinas knew nothing of).
Way 2: no effect without a cause, and this cannot go back to infinity, so there is First Cause [Aquinas]
     Full Idea: If there is no first cause among efficient causes, there is no ultimate or intermediate cause. That in efficient causes it is possible to go on to infinity is plainly false. So it is necessary to admit a first efficient cause, which everyone calls God.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply)
     A reaction: [compressed] It doesn't seem to follow at all that the First Cause is God. There could be a single thing like the Phoenix, with unique self-causing properties. Or a quantum fluctuation.
Way 3: contingent beings eventually vanish, so continuity needs a necessary being [Aquinas]
     Full Idea: That which can not-be at some time is not. So if everything can not-be, then once there was nothing in existence. If so, it would have been impossible for anything to have begun to exist. So there must be some being having of itself its own necessity.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply)
     A reaction: [compressed] Why can't things take it in turns to not-be, so that something is always on duty? Maybe it is a feature of things that they bring other things into existence (e.g. virtual particles)?
Way 4: the source of all qualities is their maximum, so something (God) causes all perfections [Aquinas]
     Full Idea: More and less are predicated of different things according as they resemble in their different ways something which is the maximum. The maximum of a genus is the cause of all in that genus. So there must be something causing the perfections of all beings.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply)
     A reaction: [compressed] The argument makes a startling jump from each quality (like heat or nobility) having a maximum, to their being a single entity (a 'being' at that) which is the sole source of all human perfections.
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
Way 5: mindless things act towards an obvious end, so there is an intelligent director [Aquinas]
     Full Idea: Things which lack knowledge, such as natural bodies, act for an end, which is usually in the same way, to obtain the best result. Hence they achieve their end designedly. Hence some intelligent being exists by whom all natural things are directed.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply)
     A reaction: [compressed] This is Greek teleology with a vengeance. Plants probably illustrate best what he has in mind. There is obvious teleology in human affairs, and there is a sort of teleology in living things, but we take the end to be reinforced by success.
29. Religion / B. Monotheistic Religion / 4. Christianity / a. Christianity
Life aims at the Beatific Vision - of perfect happiness, and revealed truth [Aquinas, by Zagzebski]
     Full Idea: Aquinas describes the ultimate end of human life as the Beatific Vision, a state that is simultaneously the enjoyment of perfect happiness and a perfect revelation of truth.
     From: report of Thomas Aquinas (Summa Theologicae [1265]) by Linda Trinkaus Zagzebski - Virtues of the Mind II 4.2
     A reaction: I like that a lot, even though my idea of the revelation of truth is very distant from that of Aquinas. Ignorant happiness is not much of an aspiration.
29. Religion / B. Monotheistic Religion / 4. Christianity / c. Angels
Aquinas saw angels as separated forms, rather than as made of 'spiritual matter' [Aquinas, by Kretzmann/Stump]
     Full Idea: Unlike some of his contemporaries, Aquinas does not think that there is a 'spiritual matter' that angels or disembodied souls have as one of their components, but rather that they are separated forms that configure no matter at all.
     From: report of Thomas Aquinas (Summa Theologicae [1265]) by Kretzmann/Stump - Aquinas, Thomas 10
     A reaction: 'Separated forms' sounds like the modern concept of abstract entities, meaning that souls and angels exist in the way that platonists believe numbers exist. How else might Aquinas have understood them?
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
Humans have a non-physical faculty of reason, so they can be immortal [Aquinas, by Sorabji]
     Full Idea: Aquinas infers from Aristotle that intellectual understanding is the only operation of the soul that is performed without a physical organ, so that only human souls, and not animal ones, can be immortal.
     From: report of Thomas Aquinas (Summa Theologicae [1265], I, q75, a3, resp) by Richard Sorabji - Rationality 'Reason'
     A reaction: This shows why so many thinkers are desperate to hang on to dualism, of some sort. Interesting that he only claims partial dualism.
29. Religion / D. Religious Issues / 2. Immortality / d. Heaven
Those in bliss have their happiness increased by seeing the damned punished [Aquinas]
     Full Idea: In order that the bliss of the saints may be more delightful for them, and they may render more copious thanks to God for it, it is given to them to see perfectly the punishment of the damned.
     From: Thomas Aquinas (Summa Theologicae [1265], III Supp Q94,1), quoted by Friedrich Nietzsche - On the Genealogy of Morals I.§15
     A reaction: This has probably been repudiated by the Church of England. Justice should be seen to be done. Presumably you mustn't gloat, or you join them.
29. Religion / D. Religious Issues / 3. Problem of Evil / a. Problem of Evil
God does not exist, because He is infinite and good, and so no evil should be discoverable [Aquinas]
     Full Idea: If one of two contraries be infinite, the other would be altogether destroyed. But the name God means that He is infinite goodness. If therefore God existed there would be no evil discoverable; but there is evil in the world. Therefore God does not exist.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob1)
     A reaction: This is not, of course, the opinion of Aquinas. I love the way he states the opposition's arguments so lucidly. The modern problem usually talks of God's omnipotence, rather than infinity. His formulation allows that there might be undiscoverable evil.
It is part of God's supreme goodness that He brings good even out of evil [Aquinas]
     Full Idea: As Augustine says, God would not allow any evil to exist in his works, unless he were to bring good even out of evil. It is part of the infinite goodness of God, that He allows evil to exist and out of it produces good.
     From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob1rep)
     A reaction: Are God's powers so limited that He could not have achieved an equal amount of good without having to indulge in some evil first?
