19693 | There is practical wisdom (for action), and theoretical wisdom (for deep understanding) [Aristotle, by Whitcomb] |
Full Idea: Aristotle takes wisdom to come in two forms, the practical and the theoretical, the former of which is good judgement about how to act, and the latter of which is deep knowledge or understanding. | |
From: report of Aristotle (works [c.330 BCE]) by Dennis Whitcomb - Wisdom Intro | |
A reaction: The interesting question is then whether the two are connected. One might be thoroughly 'sensible' about action, without counting as 'wise', which seems to require a broader view of what is being done. Whitcomb endorses Aristotle on this idea. |
19073 | True philosophy aims at absolute unity, while our understanding sees only separation [Hegel] |
Full Idea: Everything deserving the name of philosophy has constantly been based on the consciousness of an absolute unity, where the understanding sees and accepts only separation. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: Puzzled by the role of 'understanding' here. I tend to cite that as the highest aspiration of philosophy. Hegel seems to offer a higher understanding of unity, and a weaker analytic understanding, which is part of our limited psychology. |
15624 | Free thinking has no presuppositions [Hegel] |
Full Idea: Thinking that is free is without presuppositions. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §41 Add1) | |
A reaction: Fat chance, I would have thought. Hegel's project was indeed to try to get right to the bottom of the presuppositions. My picture is always of holding one thing presupposed while you examine another, and then switching to other presuppositions. |
15631 | The ideal of reason is the unification of abstract identity (or 'concept') and being [Hegel] |
Full Idea: Abstract identity (which is what here is also called 'concept') and being are the two moments that reason seeks to unify; this unification is the Ideal of reason. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §49) | |
A reaction: Not sure I understand this, but I connect it to Aristotle's approach to the problem of being, which was to abandon the head-on approach, and aim to understand the identities of particulars and kinds. |
15612 | Older metaphysics naively assumed that thought grasped things in themselves [Hegel] |
Full Idea: The older metaphysics has the naïve presupposition that thinking grasps what things are in-themselves, that things only are what they genuinely are when they are captured in thought. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §28 Add) | |
A reaction: His 'older' metaphysics is prior to Kant's critique. The less naïve version is more aware of antinomies and dialectical conflicts within thought. |
21768 | Logic is metaphysics, the science of things grasped in thoughts [Hegel] |
Full Idea: Logic coincides with metaphysics, with the science of things grasped in thoughts. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §24), quoted by Stephen Houlgate - An Introduction to Hegel 02 'Logic' | |
A reaction: Not a very clear definition, given that thinking about a table appears to be a 'thing grasped in thought'. Presumably it refers to things which can only be grasped in thought, which seems to make it entirely a priori. |
21984 | We must break up the rigidity that our understanding has imposed [Hegel] |
Full Idea: The battle of reason is the struggle to break up the rigidity to which the understanding has reduced everything. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §80Z p.115), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.7 | |
A reaction: This sounds like a combination of Nietzsche and later Wittgenstein, and may be one of the ideas that launches 'continental' philosophy. Recent French thinkers talk continually of 'liberation'. |
1575 | For Aristotle logos is essentially the ability to talk rationally about questions of value [Roochnik on Aristotle] |
Full Idea: For Aristotle logos is the ability to speak rationally about, with the hope of attaining knowledge, questions of value. | |
From: comment on Aristotle (works [c.330 BCE]) by David Roochnik - The Tragedy of Reason p.26 |
22081 | Let thought follow its own course, and don't interfere [Hegel] |
Full Idea: Let thought follow its own course; and I think badly whenever I add something of my own. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §24 Add 2), quoted by Stephen Houlgate - Hegel p.100 | |
A reaction: The idea that reason has a course of its own is a mega-assumption, which I would only accept after a lot of persuasion, which I doubt that Hegel can provide. The modern analytic idea of metaphysics as logic has a similar basis. |
1589 | Aristotle is the supreme optimist about the ability of logos to explain nature [Roochnik on Aristotle] |
Full Idea: Aristotle is the great theoretician who articulates a vision of a world in which natural and stable structures can be rationally discovered. His is the most optimistic and richest view of the possibilities of logos | |
From: comment on Aristotle (works [c.330 BCE]) by David Roochnik - The Tragedy of Reason p.95 |
15626 | Categories create objective experience, but are too conditioned by things to actually grasp them [Hegel] |
Full Idea: It is the categories that elevate mere perception into objectivity, into experience; but these concepts ...are conditioned by the given material. ...Hence the understanding, or cognition through categories, cannot become cognizant of things-in-themselves. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §43-4) | |
A reaction: As one often fears with Hegel, this sounds like a deep insight, but is less persuasive when translated into simpler English (if I've got it right!). Being 'conditioned by the material' strikes me as just what is needed for good categories. |
15616 | If truth is just non-contradiction, we must take care that our basic concepts aren't contradictory [Hegel] |
Full Idea: If truth were nothing more than lack of contradiction, one would have to examine first of all, with regard to each concept, whether it does not on its own account, contain an inner contradiction. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §33 Rem) | |
A reaction: This is a very nice thought, which modern analytic philosophers, steeped in logic, should think about. It is always presumed that a contradiction is between a proposition and its negation, not some inner feature. |
15615 | Older metaphysics became dogmatic, by assuming opposed assertions must be true and false [Hegel] |
Full Idea: The older metaphysics became dogmatism because, given the nature of finite determinations, it had to assume that of two opposed assertions (of the kind that those propositions were) one must be true and the other false. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §32) | |
A reaction: While dialethism in logic looks very dubious to me, I have every sympathy with Hegel when it comes to the reasonings of ordinary language. There it is much harder to know whether you are addressing truly opposed assertions. |
21767 | Dialectic is seen in popular proverbs like 'pride comes before a fall' [Hegel] |
Full Idea: In the domain of individual ethics, we find the consciousness of dialectic in those universally familiar proverbs 'pride goes before a fall' and 'too much wit outwits itself'. ...Joy relieves itself in tears, and melancholy can be revealed in a smile. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §81), quoted by Stephen Houlgate - An Introduction to Hegel 02 'The Method' | |
A reaction: 'Too clever by half' is the English version. Hegel's dialectic suggests that each concept somehow implies its opposite, rather than a mere mercurial drift from one extreme to the other. Most pride doesn't lead to a fall. |
15638 | Dialectic is the moving soul of scientific progression, the principle which binds science together [Hegel] |
Full Idea: The dialectical constitutes the moving soul of scientific progression, and it is the principle through which alone immanent coherence and necessity enter into the content of science. ..[Add 1] It is the principle of all motion, of all life. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §81) |
15639 | Socratic dialectic is subjective, but Plato made it freely scientific and objective [Hegel] |
Full Idea: It is in the Platonic philosophy that dialectic first occurs in a form which is freely scientific, and hence also objective. With Socrates, dialectical thinking still has a predominantly subjective shape, consistent with his irony. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §81 Add1) | |
A reaction: I don't understand how dialectic can be 'objective', given that it is a method rather than a belief. Plato certainly seems to elevate dialectic into something almost mystical, because of what is said to be within its power. |
8200 | Aristotelian definitions aim to give the essential properties of the thing defined [Aristotle, by Quine] |
Full Idea: A real definition, according to the Aristotelian tradition, gives the essence of the kind of thing defined. Man is defined as a rational animal, and thus rationality and animality are of the essence of each of us. | |
From: report of Aristotle (works [c.330 BCE]) by Willard Quine - Vagaries of Definition p.51 | |
A reaction: Compare Idea 4385. Personally I prefer the Aristotelian approach, but we may have to say 'We cannot identify the essence of x, and so x cannot be defined'. Compare 'his mood was hard to define' with 'his mood was hostile'. |
4385 | Aristotelian definition involves first stating the genus, then the differentia of the thing [Aristotle, by Urmson] |
Full Idea: For Aristotle, to give a definition one must first state the genus and then the differentia of the kind of thing to be defined. | |
From: report of Aristotle (works [c.330 BCE]) by J.O. Urmson - Aristotle's Doctrine of the Mean p.157 | |
A reaction: Presumably a modern definition would just be a list of properties, but Aristotle seeks the substance. How does he define a genus? - by placing it in a further genus? |
19070 | Superficial truth is knowing how something is, which is consciousness of bare correctness [Hegel] |
Full Idea: Truth is at first taken to mean that I know how something is. This is truth, however, only in reference to consciousness; it is formal truth, bare correctness. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: I would translate this idea as saying that bare correctness is conscious awareness of the truthmaker for some statement. Hegel then offers a 'deeper' account of the nature of truth. I would say awareness is quite separate from the concept of truth. |
5644 | In Hegel's logic it is concepts (rather than judgements or propositions) which are true or false [Hegel, by Scruton] |
Full Idea: The terms of Hegel's logic are not judgements or propositions, but rather concepts: and it is concepts, in this view, that are true or false. | |
From: report of Georg W.F.Hegel (Logic (Encyclopedia I) [1817]) by Roger Scruton - Short History of Modern Philosophy Ch.12 | |
A reaction: Quite alien to normal studies of logic, but I can make sense of a correspondence theory of truth for concepts, which might be more interesting than normal propositional or predicate logic. Does the concept of, say, a 'natural law' correspond to anything? |
19072 | In the deeper sense of truth, to be untrue resembles being bad; badness is untrue to a thing's nature [Hegel] |
Full Idea: When truth is viewed in the deeper sense, to be untrue means much the same as to be bad. A bad man is an untrue man, and man who does not behave as his notion or his vocation requires. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: See Idea 19071 for the 'deeper sense'. This seems to confirm that Hegel's deeper concept of truth resembles authenticity. I guess it will be something fulfilling the essence of the thing. Doctors must be proper doctors. Gold must be true gold? |
19071 | The deeper sense of truth is a thing matching the idea of what it ought to be [Hegel] |
Full Idea: Truth in the deeper sense is the identity between objectivity and the notion. It is in this deeper sense of truth that we speak of a true state or work of art. These are true if they are as they ought to be (their reality corresponds to their notion). | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §213) | |
A reaction: This seems to be a correspondence theory, but not as we know it, Jim. He seems to have a value built into truth, which sounds to me like existentialist 'authenticity'. I like what he is saying, but I would analyse it into two or more components. |
13282 | Aristotle relativises the notion of wholeness to different measures [Aristotle, by Koslicki] |
Full Idea: Aristotle proposes to relativise unity and plurality, so that a single object can be both one (indivisible) and many (divisible) simultaneously, without contradiction, relative to different measures. Wholeness has degrees, with the strength of the unity. | |
From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 7.2.12 | |
A reaction: [see Koslicki's account of Aristotle for details] As always, the Aristotelian approach looks by far the most promising. Simplistic mechanical accounts of how parts make wholes aren't going to work. We must include the conventional and conceptual bit. |
21595 | Excluded middle is the maxim of definite understanding, but just produces contradictions [Hegel] |
Full Idea: The law of excluded middle is ...the maxim of the definite understanding, which would fain avoid contradiction, but in doing so falls into it. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], p.172), quoted by Timothy Williamson - Vagueness 1.5 | |
A reaction: Not sure how this works, but he would say this, wouldn't he? |
4730 | For Aristotle, the subject-predicate structure of Greek reflected a substance-accident structure of reality [Aristotle, by O'Grady] |
Full Idea: Aristotle apparently believed that the subject-predicate structure of Greek reflected the substance-accident nature of reality. | |
From: report of Aristotle (works [c.330 BCE]) by Paul O'Grady - Relativism Ch.4 | |
A reaction: We need not assume that Aristotle is wrong. It is a chicken-and-egg. There is something obvious about subject-predicate language, if one assumes that unified objects are part of nature, and not just conventional. |
15628 | The idea that contradiction is essential to rational understanding is a key modern idea [Hegel] |
Full Idea: The thought that the contradiction which is posited by the determinations of the understanding in what is rational is essential and necessary, has to be considered one of the most important and profound advances of the philosophy of modern times. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §48) | |
A reaction: This is the aspect of Kant's philosophy which launched the whole career of Hegel. Hegel is the philosopher of the antinomies. Graham Priest is his current representative on earth. |
15629 | Tenderness for the world solves the antinomies; contradiction is in our reason, not in the essence of the world [Hegel] |
Full Idea: The solution to the antinomies is as trivial as they are profound; it consists merely in a tenderness for the things of this world. The stain of contradiction ought not to be in the essence of what is in the world; it must belong only to thinking reason. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §48 Rem) | |
A reaction: A rather Wittgensteinian remark. I love his 'tenderness for the things of this world'! I'm not clear why our thinking should be considered to be inescapably riddled with basic contradictions, as Hegel seems to imply. Just make more effort. |
15630 | Antinomies are not just in four objects, but in all objects, all representations, all objects and all ideas [Hegel] |
Full Idea: The main point that has to be made is that antinomy is found not only in Kant's four particular objects taken from cosmology, but rather in all objects of all kinds, in all representations, concepts and ideas. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §48 Rem) | |
A reaction: I suppose Heraclitus and Empedocles, with their oppositional accounts of reality, are the ancestors of this worldview. I just don't feel that sudden flood of insight from this idea of Hegel that comes from some of the other great philsophical theories. |
15634 | Thought about particulars is done entirely through categories [Hegel] |
Full Idea: As an activity of the particular, thinking has the categories as its only product and content. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §62) | |
A reaction: There seems to be an interesting implication in this remark (taken in isolation!) that one can somehow transcend the categories when one begins to think about the universal. Are the universal and the categories not connected? |
22078 | Even simple propositions about sensations are filled with categories [Hegel] |
Full Idea: Categories, like 'being', or 'individuality', are already mingled into every proposition, even when it has a completely sensible content, such as "this leaf is green". | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §246 Add), quoted by Stephen Houlgate - Hegel p.95 | |
A reaction: This is the source of the idea that observation is theory-laden (which tracks back to Kant). Not Duhem, who gets the credit among analytic philosophers. Quine obviously never read Hegel. But the idea is overrated. |
4938 | Prior to language, concepts are universals created by self-mapping of brain activity [Edelman/Tononi] |
Full Idea: Before language is present, concepts depend on the brain's ability to construct 'universals' through higher-order mapping of the activity of the brain's own perceptual and motor maps. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.15) | |
A reaction: It should be of great interest to philosophers that one can begin to give a neuro-physiological account of universals. A physical system can be ordered as a database, and universals are the higher branches of a tree-structure of information. |
21981 | The one substance is formless without the mediation of dialectical concepts [Hegel] |
Full Idea: As intuitively accepted by Spinoza without a previous mediation by dialectic, substance is as it were a dark shapeless abyss which engulfs all definite content as radically null, and produces from itself nothing that has a positive substance of its own. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §151Z p.215), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.6 | |
A reaction: This seems to be an expression of idealism, since only what is conceptualised can exist. |
13276 | The unmoved mover and the soul show Aristotelian form as the ultimate mereological atom [Aristotle, by Koslicki] |
Full Idea: Aristotle's discussion of the unmoved mover and of the soul confirms the suspicion that form, when it is not thought of as the object represented in a definition, plays the role of the ultimate mereological atom within his system. | |
From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 6.6 | |
A reaction: Aristotle is concerned with which things are 'divisible', and he cites these two examples as indivisible, but they may be too unusual to offer an actual theory of how Aristotle builds up wholes from atoms. He denies atoms in matter. |
13277 | The 'form' is the recipe for building wholes of a particular kind [Aristotle, by Koslicki] |
Full Idea: Thus in Aristotle we may think of an object's formal components as a sort of recipe for how to build wholes of that particular kind. | |
From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 7.2.5 | |
A reaction: In the elusive business of pinning down what Aristotle means by the crucial idea of 'form', this analogy strikes me as being quite illuminating. It would fit DNA in living things, and the design of an artifact. |
15637 | Essence is the essential self-positing unity of immediacy and mediation [Hegel] |
Full Idea: The entire second part of the 'Logic', the doctrine of Essence, deals with the essential self-positing unity of immediacy and mediation. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §65) | |
A reaction: He is referring to his book 'Science of Logic'. I don't really understand this, but that essence 'posits' the unity of a thing catches my attention. |
15613 | Real cognition grasps a thing from within itself, and is not satisfied with mere predicates [Hegel] |
Full Idea: In genuine cognition ...an object determines itself from within itself, and does not acquire its predicates in an external way. If we proceed by way of predication, the spirit gets the feeling that the predicates cannot exhaust what they are attached to. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §28 Add) | |
A reaction: I take this to be a glimpse of Hegel's notoriously difficult account of essence. Place this alongside Locke's distinction between Nominal and Real essences. Once we have the predicates, we want to grasp their source. |
5991 | For Aristotle, knowledge is of causes, and is theoretical, practical or productive [Aristotle, by Code] |
Full Idea: Aristotle thinks that in general we have knowledge or understanding when we grasp causes, and he distinguishes three fundamental types of knowledge - theoretical, practical and productive. | |
From: report of Aristotle (works [c.330 BCE]) by Alan D. Code - Aristotle | |
A reaction: Productive knowledge we tend to label as 'knowing how'. The centrality of causes for knowledge would get Aristotle nowadays labelled as a 'naturalist'. It is hard to disagree with his three types, though they may overlap. |
15636 | The Cogito is at the very centre of the entire concern of modern philosophy [Hegel] |
Full Idea: The proposition 'Cogito Ergo Sum' stands at the very centre, so to speak, of the entire concern of modern philosophy. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §64 Rem) | |
A reaction: I distinguish two approaches to philosophy: the Parmenidean (which starts from the nature of being), and the Cartesian (which starts from the fact of consciousness). This remark confirms that Hegel is firmly in the latter school. |
22300 | Existence is just a set of relationships [Hegel] |
Full Idea: Everything that exists stands in correlation, and this correlation is the veritable nature of existence. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], p.235 (1892)), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 23 'Abs' |
11239 | The notion of a priori truth is absent in Aristotle [Aristotle, by Politis] |
Full Idea: The notion of a priori truth is conspicuously absent in Aristotle. | |
From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.5 | |
A reaction: Cf. Idea 11240. |
15609 | The sensible is distinguished from thought by being about singular things [Hegel] |
Full Idea: The distinction of the sensible from thought is to be located in that fact that the determination of the sensible is singularity. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §20 Rem) | |
A reaction: Compare Idea 15608, where we find that thought concerns universals. What a very clear thinker Hegel was! |
15625 | Sense perception is secondary and dependent, while thought is independent and primitive [Hegel] |
Full Idea: What can be perceived by the senses is really secondary and not self-standing, while thoughts, on the contrary, are what is genuinely independent and primitive. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §41 Add2) | |
A reaction: Although this is post-Kant, it strikes me as a perfect slogan for rationalism. Personally I would say that such a dichotomy is becoming a historical relic, in the light of modern understanding of the brain. Experience and thought are inextricable. |
23312 | Aristotle is a rationalist, but reason is slowly acquired through perception and experience [Aristotle, by Frede,M] |
Full Idea: Aristotle is a rationalist …but reason for him is a disposition which we only acquire over time. Its acquisition is made possible primarily by perception and experience. | |
From: report of Aristotle (works [c.330 BCE]) by Michael Frede - Aristotle's Rationalism p.173 | |
A reaction: I would describe this process as the gradual acquisition of the skill of objectivity, which needs the right knowledge and concepts to evaluate new experiences. |
15620 | Empiricism contains the important idea that we should see knowledge for ourselves, and be part of it [Hegel] |
Full Idea: We must recognise the important principle of freedom that lies in Empiricism; namely, that what ought to count in our human knowing, we ought to see for ourselves, and to know ourselves as present in it. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §38 Rem) | |
A reaction: Like Idea 15619, this is an interesting and perceptive remark, from a philosopher who seems a long way from empiricism. I presume he will be thinking mainly of Hume, via Kant. Personally I prefer Locke. |
15619 | Empiricism made particular knowledge possible, and blocked wild claims [Hegel] |
Full Idea: Empiricism resulted from a need for concrete content, as opposed to abstract theories that cannot advance from universal generalizations to the particular, and for a firm hold against the possibility of proving any claim at all in the field. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §37) | |
A reaction: That sounds about right, and makes you wonder why Hegel wasn't an empiricist. |
15622 | Empiricism unknowingly contains and uses a metaphysic, which underlies its categories [Hegel] |
Full Idea: Empiricism operates without knowing that it contains a metaphysics and is engaged in it, and that it is using categories and their connections in a totally uncritical and unconscious manner. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §38 Rem) | |
A reaction: I doubt whether this is true of modern empiricists, who have been challenged so often from within their own ranks on so many things. I'm not even sure that it is true of Locke and Hume, apart from the way in which all philosophers are unaware of things. |
15621 | Empiricism of the finite denies the supersensible, and can only think with formal abstraction [Hegel] |
Full Idea: Inasmuch as Empiricism restricts itself to what is finite, the consistent carrying through of its programme denies the supersensible altogether, ..and it leaves thinking with abstraction only, [i.e.] with formal universality and identity. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §38 Rem) | |
A reaction: I'm not clear how a denial of empiricism allows you (with intellectual integrity) to embrace 'the supersensible'. The set theoretic account of higher levels of infinity looks like a nice test case. |
15632 | The Humean view stops us thinking about perception, and finding universals and necessities in it [Hegel] |
Full Idea: The Humean standpoint proclaims the thinking of our perceptions to be inadmissible; i.e. the eliciting of the universal and necessary out of those perceptions. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §50) | |
A reaction: Obviously Hume permits 'relations of ideas', but presumably the point is that his approach only legitimates a rather passive abstraction from experience, rather than an active application of a priori concepts to it. A fair criticism. See Bonjour. |
16111 | Aristotle wants to fit common intuitions, and therefore uses language as a guide [Aristotle, by Gill,ML] |
Full Idea: Since Aristotle generally prefers a metaphysical theory that accords with common intuitions, he frequently relies on facts about language to guide his metaphysical claims. | |
From: report of Aristotle (works [c.330 BCE]) by Mary Louise Gill - Aristotle on Substance Ch.5 | |
A reaction: I approve of his procedure. I take intuition to be largely rational justifications too complex for us to enunciate fully, and language embodies folk intuitions in its concepts (especially if the concepts occur in many languages). |
15623 | Humean scepticism, unlike ancient Greek scepticism, accepts the truth of experience as basic [Hegel] |
Full Idea: Humean scepticism should be very carefully distinguished from Greek scepticism. In Humean scepticism, the truth of the empirical, the truth of feeling and intuition is taken as basic. ..Greek scepticism turned itself against the sensible. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §39 Rem) | |
A reaction: This seems right, and Hume himself was quite contemptuous of the sort of scepticism found in the ideas of Sextus Empiricus. |
4934 | Cultures have a common core of colour naming, based on three axes of colour pairs [Edelman/Tononi] |
Full Idea: We seem to have a set of colour axes (red-green, blue-yellow, and light-dark). Color naming in different cultures tend to have universal categories based on these axes, with a few derived or composite categories (e.g. orange, purple, pink, brown, grey). | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.13) | |
A reaction: This confirms my view of all supposed relativism: that there are degrees of cultural and individual relativism possible, but it is daft to think this goes all the way down, as nature has 'joints', and our minds are part of nature. |
16971 | Plato says sciences are unified around Forms; Aristotle says they're unified around substance [Aristotle, by Moravcsik] |
Full Idea: Plato's unity of science principle states that all - legitimate - sciences are ultimately about the Forms. Aristotle's principle states that all sciences must be, ultimately, about substances, or aspects of substances. | |
From: report of Aristotle (works [c.330 BCE], 1) by Julius Moravcsik - Aristotle on Adequate Explanations 1 |
11243 | Aristotelian explanations are facts, while modern explanations depend on human conceptions [Aristotle, by Politis] |
Full Idea: For Aristotle things which explain (the explanantia) are facts, which should not be associated with the modern view that says explanations are dependent on how we conceive and describe the world (where causes are independent of us). | |
From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 2.1 | |
A reaction: There must be some room in modern thought for the Aristotelian view, if some sort of robust scientific realism is being maintained against the highly linguistic view of philosophy found in the twentieth century. |
3320 | Aristotle's standard analysis of species and genus involves specifying things in terms of something more general [Aristotle, by Benardete,JA] |
Full Idea: The standard Aristotelian doctrine of species and genus in the theory of anything whatever involves specifying what the thing is in terms of something more general. | |
From: report of Aristotle (works [c.330 BCE]) by José A. Benardete - Metaphysics: the logical approach Ch.10 |
12000 | Aristotle regularly says that essential properties explain other significant properties [Aristotle, by Kung] |
Full Idea: The view that essential properties are those in virtue of which other significant properties of the subjects under investigation can be explained is encountered repeatedly in Aristotle's work. | |
From: report of Aristotle (works [c.330 BCE]) by Joan Kung - Aristotle on Essence and Explanation IV | |
A reaction: What does 'significant' mean here? I take it that the significant properties are the ones which explain the role, function and powers of the object. |
4924 | A conscious human being rapidly reunifies its mind after any damage to the brain [Edelman/Tononi] |
Full Idea: It seems that after a massive stroke or surgical resection, a conscious human being is rapidly "resynthesised" or reunified within the limits of a solipsistic universe that, to outside appearances, is warped and restricted. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch. 3) | |
A reaction: Note that there are two types of 'unity of mind'. This comment refers to the unity of seeing oneself as a single person, rather than the smooth unbroken quality of conscious experience. I presume that there is no point in a mind without the first unity. |
4932 | A conscious state endures for about 100 milliseconds, known as the 'specious present' [Edelman/Tononi] |
Full Idea: The 'specious present' (William James), a rough estimate of the duration of a single conscious state, is of the order of 100 milliseconds, meaning that conscious states can change very rapidly. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.12) | |
A reaction: A vital feature of our subjective experience of time. I wonder what the figure is for a fly? It suggests that conscious experience really is like a movie film, composed of tiny independent 'frames' of very short duration. |
4931 | Consciousness is a process (of neural interactions), not a location, thing, property, connectivity, or activity [Edelman/Tononi] |
Full Idea: Consciousness is neither a thing, nor a simple property. ..The conscious 'dynamic core' of the brain is a process, not a thing or a place, and is defined in terms of neural interactions, not in terms of neural locations, connectivity or activity. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.12) | |
A reaction: This must be of great interest to philosophers. Edelman is adamant that it is not any specific neurons. The nice question is: what would it be like to have your brain slowed down? Presumably we would experience steps in the process. Is he a functionalist? |
4923 | The three essentials of conscious experience are privateness, unity and informativeness [Edelman/Tononi] |
Full Idea: The fundamental aspects of conscious experience that are common to all its phenomenological manifestations are: privateness, unity, and informativeness. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch. 3) | |
A reaction: Interesting, coming from neuroscientists. The list strikes me as rather passive. It is no use having good radar if you can't make decisions. Privacy and unity are overrated. Who gets 'informed'? Personal identity must be basic. |
4941 | Consciousness can create new axioms, but computers can't do that [Edelman/Tononi] |
Full Idea: Conscious human thought can create new axioms, which a computer cannot do. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.17) | |
A reaction: A nice challenge for the artificial intelligence community! I don't understand their confidence in making this assertion. Nothing in Gödel's Theorem seems to prevent the reassignment of axioms, and Quine implies that it is an easy and trivial game. |
4930 | Consciousness arises from high speed interactions between clusters of neurons [Edelman/Tononi] |
Full Idea: Our hypothesis is that the activity of a group of neurons can contribute directly to conscious experience if it is part of a functional cluster, characterized by strong interactions among a set of neuronal groups over a period of hundreds of milliseconds. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.12) | |
A reaction: This is their 'dynamic core' hypothesis. It doesn't get at the Hard Questions about consciousness, but this is a Nobel prize winner hot on the trail of the location of the action. It gives support to functionalism, because the neurons vary. |
4929 | Dreams and imagery show the brain can generate awareness and meaning without input [Edelman/Tononi] |
Full Idea: Dreaming and imagery are striking phenomenological demonstrations that the adult brain can spontaneously and intrinsically produce consciousness and meaning without any direct input from the periphery. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.11) | |
A reaction: This offers some support for Searle's claim that brain's produce 'intrinsic' (rather than 'derived') intentionality. Of course, one can have a Humean impressions/ideas theory about how the raw material got there. We SEE meaning in our experiences. |
4940 | Physicists see information as a measure of order, but for biologists it is symbolic exchange between animals [Edelman/Tononi] |
Full Idea: Physicists may define information as a measure of order in a far-from-equilibrium state, but it is best seen as a biological concept which emerged in evolution with animals that were capable of mutual symbolic exchange. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.17) | |
A reaction: The physicists' definition seems to open the road to the possibility of non-conscious intentionality (Dennett), where the biological view seems to require consciousness of symbolic meanings (Searle). Tree-rings contain potential information? |
4935 | The sensation of red is a point in neural space created by dimensions of neuronal activity [Edelman/Tononi] |
Full Idea: The pure sensation of red is a particular neural state identified by a point within the N-dimensional neural space defined by the integrated activity of all the group of neurons that constitute the dynamic core. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.13) | |
A reaction: This hardly answers the Hard Question (why experience it? why that experience?), but it is interesting to see a neuroscientist fishing for an account of qualia. He says three types of neuron firing generate the dimensions of the 'space'. |
4936 | The self is founded on bodily awareness centred in the brain stem [Edelman/Tononi] |
Full Idea: Structures in the brain stem map the state of the body and its relation to the environment, on the basis of signals with proprioceptive, kinesthetic, somatosensory and autonomic components. We may call these the dimensions of the proto-self. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.13) | |
A reaction: It seems to me that there is no free will, but moral responsibility depends on the existence of a Self, and philosophers had better fight for it (are you listening, Hume?). Fortunately neuroscientists seem to endorse it fairly unanimously. |
4939 | A sense of self begins either internally, or externally through language and society [Edelman/Tononi] |
Full Idea: Two extreme views on the development of the self are 'internalist' and 'externalist'. The first starts with a baby's subjective experience, and increasing differentiation as self-consciousness develops. The externalist view requires language and society. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.15) | |
A reaction: Edelman rightly warns against this simple dichotomy, but if I have to vote, it is for internalism. I take a sense of self as basic to any mind, even a slug's. What is a mind for, if not to look after the creature? Self makes sensation into mind. |
4925 | Brains can initiate free actions before the person is aware of their own decision [Edelman/Tononi] |
Full Idea: Libet concluded that the cerebral initiation of a spontaneous, freely voluntary act can begin unconsciously, that is, before there is any recallable awareness that a decision to act has already been initiated cerebrally. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch. 6) | |
A reaction: We should accept this result. 'Free will' was always a bogus metaphysical concept (invented, I think, because God had to be above natural laws). A person is the source of responsibility, and is the controller of the brain, but not entirely conscious. |
15617 | In abstraction, beyond finitude, freedom and necessity must exist together [Hegel] |
Full Idea: Considered as abstractly confronting one another, freedom and necessity pertain to finitude only and are valid only on its soil. A freedom with no necessity in it, and a mere necessity without freedom, are determinations that are abstract and thus untrue. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §35 Add) | |
A reaction: This is, presumably, the Hegelian dialectical nature of things, that contradictories are bound together. We must struggle hard to undestand a freedom bound by necessity, and a necessity which contains freedom. (Good luck). |
4933 | Consciousness is a process, not a thing, as it maintains unity as its composition changes [Edelman/Tononi] |
Full Idea: The conscious 'dynamic core' of the brain can maintain its unity over time even if its composition may be constantly changing, which is the signature of a process as opposed to a thing. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.12) | |
A reaction: This is the functionalists' claim that the mind is 'multiply realisable', since different neurons can maintain the same process. 'Process' strikes me as a much better word than 'function'. These theories capture passive mental life better than active. |
15608 | The act of thinking is the bringing forth of universals [Hegel] |
Full Idea: Thinking as an activity is the active universal, and indeed the self-actuating universal, since the act, or what is brought forth, is precisely the universal. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §20) | |
A reaction: One should contemplate animal thought in the light of this remark. Thought requires the recognition of types of things, and resemblances, and repetitions, and patterns. Language consists almost entirely of universals. |
23300 | Aristotle and the Stoics denied rationality to animals, while Platonists affirmed it [Aristotle, by Sorabji] |
Full Idea: Aristotle, and also the Stoics, denied rationality to animals. …The Platonists, the Pythagoreans, and some more independent Aristotelians, did grant reason and intellect to animals. | |
From: report of Aristotle (works [c.330 BCE]) by Richard Sorabji - Rationality 'Denial' | |
A reaction: This is not the same as affirming or denying their consciousness. The debate depends on how rationality is conceived. |
21986 | Hegel's system has a vast number of basic concepts [Hegel, by Moore,AW] |
Full Idea: For Hegel the full system of concepts ...contains many more than Kant's twelve. | |
From: report of Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §60Z) by A.W. Moore - The Evolution of Modern Metaphysics 07.7 | |
A reaction: This offers some sort of conceptual scheme, but not the structured one that Kant proposes. The sequence of dialectical mediation imposes some sort of shape on the concepts. |
4928 | Brain complexity balances segregation and integration, like a good team of specialists [Edelman/Tononi] |
Full Idea: A theoretical analysis of complexity suggests that neuronal complexity strikes an optimum balance between segregation and integration, which fits the view of the brain as a collection of specialists who talk to each other a lot. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.11) | |
A reaction: This is a theoretical point, but comes from a leading neuroscientist, and seems to endorse Fodor's modularity proposal. For a philosopher, one of the issues here is how to reconcile the segregation with the Cartesian unity and personal identity of a mind. |
4927 | Information-processing views of the brain assume the existence of 'information', and dubious brain codes [Edelman/Tononi] |
Full Idea: So-called information-processing views of the brain have been criticized because they typically assume the existence in the world of previously defined information, and often assume the existence of precise neural codes for which there is no evidence. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.11) | |
A reaction: Fodor is the target here. Searle is keen that 'intrinsic intentionality' is required to see something as 'information'. It is hard to see how anything acquires significance as it flows through a mechanical process. |
4922 | Consciousness involves interaction with persons and the world, as well as brain functions [Edelman/Tononi] |
Full Idea: We emphatically do not identify consciousness in its full range as arising solely in the brain, since we believe that higher brain functions require interactions both with the world and with other persons. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Pref) | |
A reaction: Would you gradually lose higher brain functions if you lived entirely alone? Intriguingly, this sounds like a neuroscientist asserting the necessity for broad content in order to understand the brain. |
15607 | We don't think with concepts - we think the concepts [Hegel] |
Full Idea: There is a saying that, when we have grasped a concept, we still do not know what to think with it. But there is nothing to be thought with a concept save the concept itself. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §03 Rem) | |
A reaction: Analytic philosophers should read Hegel on concepts, because he approaches the matter so very differently, and seems to be the root of the continental approach to such things. He seems to me to talk more sense than Frege on the subject. |
15610 | Active thought about objects produces the universal, which is what is true and essential of it [Hegel] |
Full Idea: When thinking is taken as active with regard to ob-jects, as the thinking-over of something, then the universal - as the product of the activity - contains the value of the matter, what is essential, inner, true. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §21) | |
A reaction: I prefer to talk of 'general terms' rather than 'universals'. If 'tiger' is coined for the first one, but must be applicable to subsequent tigers, it has to generalise what they all have in common. Locke's 'nominal' essence, I would say. |
5793 | Concepts and generalisations result from brain 'global mapping' by 'reentry' [Edelman/Tononi, by Searle] |
Full Idea: When you get maps all over the brain signalling to each other by reentry you have what Edelman calls 'global mapping', and this allows the system not only to have perceptual categories and generalisation, but also to coordinate perception and action. | |
From: report of G Edelman / G Tononi (Consciousness: matter becomes imagination [2000]) by John Searle - The Mystery of Consciousness Ch.3 | |
A reaction: This is the nearest we have got to a proper scientific account of thought (as opposed to untested speculation about Turing machines). Something like this account must be right. A concept is a sustained process, not a static item. |
4926 | Concepts arise when the brain maps its own activities [Edelman/Tononi] |
Full Idea: We propose that concepts arise from the mapping by the brain itself of the activity of the brain's own areas and regions. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch. 9) | |
A reaction: Yes. One should add that the brain appears to be physically constructed with the logic of a filing system, which would mean that our concepts were labels for files within the system. Nature generates some of the files, and thinking creates the others. |
11240 | The notion of analytic truth is absent in Aristotle [Aristotle, by Politis] |
Full Idea: The notion of analytic truth is conspicuously absent in Aristotle. | |
From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.5 | |
A reaction: Cf. Idea 11239. |
6559 | Aristotle never actually says that man is a rational animal [Aristotle, by Fogelin] |
Full Idea: To the best of my knowledge (and somewhat to my surprise), Aristotle never actually says that man is a rational animal; however, he all but says it. | |
From: report of Aristotle (works [c.330 BCE]) by Robert Fogelin - Walking the Tightrope of Reason Ch.1 | |
A reaction: When I read this I thought that this database would prove Fogelin wrong, but it actually supports him, as I can't find it in Aristotle either. Descartes refers to it in Med.Two. In Idea 5133 Aristotle does say that man is a 'social being'. But 22586! |
4937 | Systems that generate a sense of value are basic to the primitive brain [Edelman/Tononi] |
Full Idea: Early and central in the development of the brain are the dimensions provided by value systems indicating salience for the entire organism. | |
From: G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.13) | |
A reaction: This doesn't quite meet Hume's challenge to find values in the whole of nature, but it matches Charles Taylor's claim that for humans values are knowable a priori. Conditional values can be facts of the whole of nature. "If there is life, x has value..". |
11150 | It is the mark of an educated mind to be able to entertain an idea without accepting it [Aristotle] |
Full Idea: It is the mark of an educated mind to be able to entertain an idea without accepting it. | |
From: Aristotle (works [c.330 BCE]) | |
A reaction: The epigraph on a David Chalmers website. A wonderful remark, and it should be on the wall of every beginners' philosophy class. However, while it is in the spirit of Aristotle, it appears to be a misattribution with no ancient provenance. |
3037 | Aristotle said the educated were superior to the uneducated as the living are to the dead [Aristotle, by Diog. Laertius] |
Full Idea: Aristotle was asked how much educated men were superior to those uneducated; "As much," he said, "as the living are to the dead." | |
From: report of Aristotle (works [c.330 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 05.1.11 |
8660 | There are potential infinities (never running out), but actual infinity is incoherent [Aristotle, by Friend] |
Full Idea: Aristotle developed his own distinction between potential infinity (never running out) and actual infinity (there being a collection of an actual infinite number of things, such as places, times, objects). He decided that actual infinity was incoherent. | |
From: report of Aristotle (works [c.330 BCE]) by Michèle Friend - Introducing the Philosophy of Mathematics 1.3 | |
A reaction: Friend argues, plausibly, that this won't do, since potential infinity doesn't make much sense if there is not an actual infinity of things to supply the demand. It seems to just illustrate how boggling and uncongenial infinity was to Aristotle. |
12058 | Aristotle's matter can become any other kind of matter [Aristotle, by Wiggins] |
Full Idea: Aristotle's conception of matter permits any kind of matter to become any other kind of matter. | |
From: report of Aristotle (works [c.330 BCE]) by David Wiggins - Substance 4.11.2 | |
A reaction: This is obviously crucial background information when we read Aristotle on matter. Our 92+ elements, and fixed fundamental particles, gives a quite different picture. Aristotle would discuss form and matter quite differently now. |
15614 | Old metaphysics tried to grasp eternal truths through causal events, which is impossible [Hegel] |
Full Idea: When finite things are grasped according to the determinations of cause and effect they are known in their finitude. But objects of reason cannot be determined through such finite predicates, and the attempt to do this was the defect of older metaphysics. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §28 Add) | |
A reaction: This sounds the launching point for a grand philosophical system which makes scientifically inclined philosophers feel very nervous indeed. I think I prefer the old (pre-Kantian) metaphysics. |
15635 | The older conception of God was emptied of human features, to make it worthy of the Infinite [Hegel] |
Full Idea: In earlier times, every type of so-called anthropomorphic representation was banished from God as finite, and hence unworthy of the Infinite; and as a result he had already grown into something remarkably empty. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §62 Rem) | |
A reaction: Hegel favoured Christianity, because of its human aspect. His description fits Islam, where indeed the concept of God seems so drain of particularity that there is little in it to doubt, which might explain the durability of that religion. |
21980 | God is the absolute thing, and also the absolute person [Hegel] |
Full Idea: It is true that God ...is the absolute thing: he is however no less the absolute person. That he is the absolute person however is a point which the philosophy of Spinoza never reached. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], I §151Z p.214), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.6 | |
A reaction: Moore says Hegel was a Spinozist, in his commitment to a single substance, but his idea of God is very different, presumably because consciousness and concepts are so important to Hegel. Hegel needs a Lockean abstract notion of 'person' here. |
15618 | If God is the abstract of Supremely Real Essence, then God is a mere Beyond, and unknowable [Hegel] |
Full Idea: When the concept of God is apprehended merely as that of the abstract of Supremely Real Essence, then God becomes for us a mere Beyond, and there can be no further talk of the cognition of God. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §36 Add) |
15633 | We establish unification of the Ideal by the ontological proof, deriving being from abstraction of thinking [Hegel] |
Full Idea: One unification through which the Ideal is to be established starts from the abstraction of thinking and goes on to the determination for which being alone remains; this is the ontological proof that God is there. | |
From: Georg W.F.Hegel (Logic (Encyclopedia I) [1817], §51) | |
A reaction: It should come as no surprise that a philosopher who so passionately endorses pure thinking, in opposition to empiricism, should end up endorsing the highly implausible ontological argument for God's existence. Jacquette gets existence from reason. |
22729 | The concepts of gods arose from observing the soul, and the cosmos [Aristotle, by Sext.Empiricus] |
Full Idea: Aristotle said that the conception of gods arose among mankind from two originating causes, namely from events which concern the soul and from celestial phenomena. | |
From: report of Aristotle (works [c.330 BCE], Frag 10) by Sextus Empiricus - Against the Physicists (two books) I.20 | |
A reaction: The cosmos suggests order, and possible creation. What do events of the soul suggest? It doesn't seem to be its non-physical nature, because Aristotle is more of a functionalist. Puzzling. (It says later that gods are like the soul). |
