1. Philosophy / A. Wisdom / 1. Nature of Wisdom
Cicero sees wisdom in terms of knowledge, but earlier Stoics saw it as moral [Cicero, by Long]
     Full Idea: Cicero (drawing on Panaetius) treats wisdom as if its province were primarily a disinterested pursuit of knowledge. But earlier Stoics gave purely moral definitions of wisdom.
     From: report of M. Tullius Cicero (On Duties ('De Officiis') [c.44 BCE], 1.11-20) by A.A. Long - Hellenistic Philosophy 5
     A reaction: I would have thought that after long discussion most ancient (and even modern) philosophers would conclude that it is both. The 'intellectualism' of Socrates hovers in the background, implying that healthy knowledge produces virtue.
1. Philosophy / A. Wisdom / 2. Wise People
Unfortunately we choose a way of life before we are old enough to think clearly [Cicero]
     Full Idea: At the beginning of adolescence when our deliberative capacities are weak we decide on the way of life that we find attractive. So one gets entangled in a definite manner and pattern of life before one is able to judge which one is best.
     From: M. Tullius Cicero (On Duties ('De Officiis') [c.44 BCE], 1.117)
     A reaction: Hence it is important to have lots of means for bailing out of education courses, jobs, and even marriage. At least university postpones the key life choices till the early twenties.
A wise man has integrity, firmness of will, nobility, consistency, sobriety, patience [Cicero]
     Full Idea: The wise man does nothing of which he can repent, nothing against his will, does everything nobly, consistently, soberly, rightly, not looking forward to anything as bound to come, is not astonished at any novel occurrence, abides by his own decisions.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], V.xxviii)
     A reaction: Notice that the wise man never exhibits weakness of will (an Aristotelian virtue), and is consistent (as Kant proposed), and is patient (as the Stoics proposed). But Cicero doesn't think he should busy himself maximising happiness.
1. Philosophy / B. History of Ideas / 3. Greek-English Lexicon
Agathon: good [PG]
     Full Idea: Agathon: good, the highest good
     From: PG (Db (lexicon) [c.1001 BCE], 01)
Aisthesis: perception, sensation, consciousness [PG]
     Full Idea: Aisthesis: perception, sensation, consciousness
     From: PG (Db (lexicon) [c.1001 BCE], 02)
Aitia / aition: cause, explanation [PG]
     Full Idea: Aitia / aition: cause, explanation
     From: PG (Db (lexicon) [c.1001 BCE], 03)
     A reaction: The consensus is that 'explanation' is the better translation, and hence that the famous Four Causes (in 'Physics') must really be understood as the Four Modes of Explanation. They then make far more sense.
Akrasia: lack of control, weakness of will [PG]
     Full Idea: Akrasia: lack of control, weakness of will
     From: PG (Db (lexicon) [c.1001 BCE], 04)
     A reaction: The whole Greek debate (and modern debate, I would say) makes much more sense if we stick to 'lack of control' as the translation, and forget about weakness of will - and certainly give up 'incontinence' as a translation.
Aletheia: truth [PG]
     Full Idea: Aletheia: truth
     From: PG (Db (lexicon) [c.1001 BCE], 05)
Anamnesis: recollection, remembrance [PG]
     Full Idea: Anamnesis: recollection, remembrance
     From: PG (Db (lexicon) [c.1001 BCE], 06)
     A reaction: This is used for Plato's doctrine that we recollect past lives.

     Full Idea: Apeiron: the unlimited, indefinite
     From: PG (Db (lexicon) [c.1001 BCE], 10)
     A reaction: Key term in the philosophy of Anaximander, the one unknowable underlying element.
Aphairesis: taking away, abstraction [PG]
     Full Idea: Aphairesis: taking away, abstraction
     From: PG (Db (lexicon) [c.1001 BCE], 11)

     Full Idea: Apodeixis: demonstration, proof
     From: PG (Db (lexicon) [c.1001 BCE], 12)

     Full Idea: Aporia: puzzle, question, anomaly
     From: PG (Db (lexicon) [c.1001 BCE], 13)
Arche: first principle, the basic [PG]
     Full Idea: Arché: first principle, the basic
     From: PG (Db (lexicon) [c.1001 BCE], 14)
     A reaction: Interchangeable with 'aitia' by Aristotle. The first principle and the cause are almost identical.
Arete: virtue, excellence [PG]
     Full Idea: Areté: virtue, excellence
     From: PG (Db (lexicon) [c.1001 BCE], 15)
     A reaction: The word hovers between moral excellence and being good at what you do. Annas defends the older translation as 'virtue', rather than the modern 'excellence'.
Chronismos: separation [PG]
     Full Idea: Chronismos: separation
     From: PG (Db (lexicon) [c.1001 BCE], 16)
Diairesis: division [PG]
     Full Idea: Diairesis: division, distinction
     From: PG (Db (lexicon) [c.1001 BCE], 17)

     Full Idea: Diaphora: difference
     From: PG (Db (lexicon) [c.1001 BCE], 22)
Dikaiosune: moral goodness, justice [PG]
     Full Idea: Dikaiosune: moral goodness, justice
     From: PG (Db (lexicon) [c.1001 BCE], 23)
     A reaction: Usually translated as 'justice' in 'Republic', but it is a general term of moral approbation, not like the modern political and legal notion of 'justice'. 'Justice' actually seems to be bad translation.
Doxa: opinion, belief [PG]
     Full Idea: Doxa: opinion, belief, judgement
     From: PG (Db (lexicon) [c.1001 BCE], 24)
Dunamis: faculty, potentiality, capacity [PG]
     Full Idea: Dunamis: faculty, potentiality, capacity
     From: PG (Db (lexicon) [c.1001 BCE], 25)
Eidos: form, idea [PG]
     Full Idea: Eidos: form, idea
     From: PG (Db (lexicon) [c.1001 BCE], 26)
     A reaction: In Plato it is the word best translated as 'Form' (Theory of...); in Aritotle's 'Categories' it designates the species, and in 'Metaphysics' it ends up naming the structural form of the species (and hence the essence) [Wedin p.120]
Elenchos: elenchus, interrogation [PG]
     Full Idea: Elenchos: elenchus, interrogation
     From: PG (Db (lexicon) [c.1001 BCE], 27)
Empeiron: experience [PG]
     Full Idea: Empeiron: experience
     From: PG (Db (lexicon) [c.1001 BCE], 28)

     From: PG (Db (lexicon) [c.1001 BCE], 31)
Enkrateia: control [PG]
     Full Idea: Enkrateia: control
     From: PG (Db (lexicon) [c.1001 BCE], 32)
     A reaction: See 'akrasia', of which this is the opposite. The enkratic person is controlled.
Entelecheia: entelechy, having an end [PG]
     Full Idea: Entelecheia: entelechy, having an end
     From: PG (Db (lexicon) [c.1001 BCE], 33)
Epagoge: induction, explanation [PG]
     Full Idea: Epagoge: induction, explanation, leading on
     From: PG (Db (lexicon) [c.1001 BCE], 34)
Episteme: knowledge, understanding [PG]
     Full Idea: Episteme: knowledge, understanding
     From: PG (Db (lexicon) [c.1001 BCE], 35)
     A reaction: Note that 'episteme' can form a plural in Greek, but we can't say 'knowledges', so we have to say 'branches of knowledge', or 'sciences'.
Epithumia: appetite [PG]
     Full Idea: Epithumia: appetite
     From: PG (Db (lexicon) [c.1001 BCE], 36)
Ergon: function [PG]
     Full Idea: Ergon: function, work
     From: PG (Db (lexicon) [c.1001 BCE], 37)
Eristic: polemic, disputation [PG]
     Full Idea: Eristic: polemic, disputation
     From: PG (Db (lexicon) [c.1001 BCE], 38)
     A reaction: This is confrontational argument, rather than the subtle co-operative dialogue of dialectic. British law courts and the House of Commons are founded on eristic, rather than on dialectic. Could there be a dialectical elected assembly?
Eros: love [PG]
     Full Idea: Eros: love, desire
     From: PG (Db (lexicon) [c.1001 BCE], 41)
Eudaimonia: flourishing, happiness, fulfilment [PG]
     Full Idea: Eudaimonia: flourishing, happiness, fulfilment
     From: PG (Db (lexicon) [c.1001 BCE], 42)
     A reaction: Some people defend 'happiness' as the translation, but that seems to me wildly misleading, since eudaimonia is something like life going well, and certainly isn't a psychological state - and definitely not pleasure.
Genos: type, genus [PG]
     Full Idea: Genos: type, genus, kind
     From: PG (Db (lexicon) [c.1001 BCE], 43)
Hexis: state, habit [PG]

     From: PG (Db (lexicon) [c.1001 BCE], 44)

     From: PG (Db (lexicon) [c.1001 BCE], 45)
Hule: matter [PG]
     Full Idea: Hule: matter
     From: PG (Db (lexicon) [c.1001 BCE], 46)
     A reaction: The first half of the 'hylomorphism' of Aristotle. See 'morphe'!
Hupokeimenon: subject, underlying thing [cf. Tode ti] [PG]
     Full Idea: Hupokeimenon: subject, underlying thing, substratum [cf. Tode ti]
     From: PG (Db (lexicon) [c.1001 BCE], 47)
     A reaction: Literally 'that which lies under'. Latin version is 'substratum'. In Aristotle it is the problem, of explaining what lies under. It is not the theory that there is some entity called a 'substratum'.
Kalos / kalon: beauty, fineness, nobility [PG]
     Full Idea: Kalos / kalon: beauty, fineness, nobility
     From: PG (Db (lexicon) [c.1001 BCE], 48)
     A reaction: A revealing Greek word, which is not only our rather pure notion of 'beauty', but also seems to mean something like wow!, and (very suggestive, this) applies as much to actions as to objects.
Kath' hauto: in virtue of itself, essentially [PG]
     Full Idea: Kath' hauto: in virtue of itself, essentially
     From: PG (Db (lexicon) [c.1001 BCE], 51)

     Full Idea: Kinesis: movement, process, change
     From: PG (Db (lexicon) [c.1001 BCE], 52)

     From: PG (Db (lexicon) [c.1001 BCE], 53)
Logos: reason, account, word [PG]
     Full Idea: Logos: reason, account, word
     From: PG (Db (lexicon) [c.1001 BCE], 54)
Meson: the mean [PG]
     Full Idea: Meson: the mean
     From: PG (Db (lexicon) [c.1001 BCE], 55)
     A reaction: This is not the 'average', and hence not some theoretical mid-point. I would call it the 'appropriate compromise', remembering that an extreme may be appropriate in certain circumstances.
Metechein: partaking, sharing [PG]
     Full Idea: Metechein: partaking, sharing
     From: PG (Db (lexicon) [c.1001 BCE], 56)
     A reaction: The key word in Plato for the difficult question of the relationships between the Forms and the particulars. The latter 'partake' of the former. Hm. Compare modern 'instantiation', which strikes me as being equally problematic.
Mimesis: imitation, fine art [PG]
     Full Idea: Mimesis: imitation, fine art
     From: PG (Db (lexicon) [c.1001 BCE], 57)
Morphe: form [PG]
     Full Idea: Morphe: form
     From: PG (Db (lexicon) [c.1001 BCE], 58)
Noesis: intellection, rational thought [cf. Dianoia] [PG]
     Full Idea: Noesis: intellection, rational thought [cf. Dianoia]
     From: PG (Db (lexicon) [c.1001 BCE], 59)
Nomos: convention, law, custom [PG]
     Full Idea: Nomos: convention, law, custom
     From: PG (Db (lexicon) [c.1001 BCE], 61)
Nous: intuition, intellect, understanding [PG]
     Full Idea: Nous: intuition, intellect
     From: PG (Db (lexicon) [c.1001 BCE], 62)
     A reaction: There is a condensed discussion of 'nous' in Aristotle's Posterior Analytics B.19
Orexis: desire [PG]
     Full Idea: Orexis: desire
     From: PG (Db (lexicon) [c.1001 BCE], 63)
Ousia: substance, (primary) being, [see 'Prote ousia'] [PG]
     Full Idea: Ousia: substance, (primary) being [see 'Prote ousia']
     From: PG (Db (lexicon) [c.1001 BCE], 64)
     A reaction: It is based on the verb 'to be'. Latin therefore translated it as 'essentia' (esse: to be), and we have ended up translating it as 'essence', but this is wrong! 'Being' is the best translation, and 'substance' is OK. It is the problem, not the answer.
Pathos: emotion, affection, property [PG]
     Full Idea: Pathos: emotion, affection, property
     From: PG (Db (lexicon) [c.1001 BCE], 65)
Phantasia: imagination [PG]
     Full Idea: Phantasia: imagination
     From: PG (Db (lexicon) [c.1001 BCE], 66)
Philia: friendship [PG]
     Full Idea: Philia: friendship
     From: PG (Db (lexicon) [c.1001 BCE], 67)
Philosophia: philosophy, love of wisdom [PG]
     Full Idea: Philosophia: philosophy, love of wisdom
     From: PG (Db (lexicon) [c.1001 BCE], 68)
     A reaction: The point of the word is its claim only to love wisdom, and not actually to be wise.
Phronesis: prudence, practical reason, common sense [PG]
     Full Idea: Phronesis: prudence, practical reason, common sense
     From: PG (Db (lexicon) [c.1001 BCE], 71)
     A reaction: None of the experts use my own translation, which is 'common sense', but that seems to me to perfectly fit all of Aristotle's discussions of the word in 'Ethics'. 'Prudence' seems a daft translation in modern English.
Physis: nature [PG]
     Full Idea: Physis: nature
     From: PG (Db (lexicon) [c.1001 BCE], 72)
Praxis: action, activity [PG]
     Full Idea: Praxis: action, activity
     From: PG (Db (lexicon) [c.1001 BCE], 73)
Prote ousia: primary being [PG]
     Full Idea: Prote ousia: primary being
     From: PG (Db (lexicon) [c.1001 BCE], 74)
     A reaction: The main topic of investigation in Aristotle's 'Metaphysics'. 'Ousia' is the central problem of the text, NOT the answer to the problem.
Psuche: mind, soul, life [PG]
     Full Idea: Psuche: mind, soul, life
     From: PG (Db (lexicon) [c.1001 BCE], 75)
     A reaction: The interesting thing about this is that we have tended to translate it as 'soul', but Aristotle says plants have it, and not merely conscious beings. It is something like the 'form' of a living thing, but then 'form' is a misleading translation too.
Sophia: wisdom [PG]
     Full Idea: Sophia: wisdom
     From: PG (Db (lexicon) [c.1001 BCE], 76)
Sophrosune: moderation, self-control [PG]
     Full Idea: Sophrosune: moderation, self-control

     Full Idea: Sullogismos: deduction, syllogism
     From: PG (Db (lexicon) [c.1001 BCE], 81)

     Full Idea: Techne: skill, practical knowledge
     From: PG (Db (lexicon) [c.1001 BCE], 82)

     From: PG (Db (lexicon) [c.1001 BCE], 87)
To ti en einai: essence, what-it-is-to-be [PG]
     Full Idea: To ti en einai: essence, what-it-is-to-be
     From: PG (Db (lexicon) [c.1001 BCE], 88)
     A reaction: This is Aristotle's main term for what we would now call the 'essence'. It is still not a theory of essence, merely an identification of the target. 'Form' is the nearest we get to his actual theory.
To ti estin: essence [PG]
     Full Idea: To ti estin: essence
     From: PG (Db (lexicon) [c.1001 BCE], 91)
Tode ti: this-such, subject of predication [cf. hupokeimenon] [PG]
     Full Idea: Tode ti: this-something, subject of predication, thisness [cf. hupokeimenon]
     From: PG (Db (lexicon) [c.1001 BCE], 92)

1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / e. Philosophy as reason
Philosophy is the collection of rational arguments [Cicero]
     Full Idea: Philosophy consists in the collection of rational arguments. [Philosophia ex rationum collatione constet]
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], IV.xxxviii.84)
     A reaction: A nice epigraph for this database. Philosophy is, I trust, a little more than that, because you don't just hide them away in a drawer. But if you arrange them nicely in a museum (a website, for example), not a lot more can be done.
1. Philosophy / F. Analytic Philosophy / 5. Linguistic Analysis
Note that "is" can assert existence, or predication, or identity, or classification [PG]
     Full Idea: There are four uses of the word "is" in English: as existence ('he is at home'), as predication ('he is tall'), as identity ('he is the man I saw'), and as classification ('he is British').
     From: PG (Db (ideas) [2031])
     A reaction: This seems a nice instance of the sort of point made by analytical philosophy, which can lead to horrible confusion in other breeds of philosophy when it is overlooked.
2. Reason / C. Styles of Reason / 1. Dialectic
Dialectic is speech cast in the form of logical argument [Cicero]
     Full Idea: Dialectic is speech cast in the form of logical argument.
     From: M. Tullius Cicero (Academica [c.45 BCE], I.viii.32)
2. Reason / F. Fallacies / 1. Fallacy
Fallacies are errors in reasoning, 'formal' if a clear rule is breached, and 'informal' if more general [PG]
     Full Idea: Fallacies are errors in reasoning, labelled as 'formal' if a clear rule has been breached, and 'informal' if some less precise error has been made.
     From: PG (Db (ideas) [2031])
     A reaction: Presumably there can be a grey area between the two.
2. Reason / F. Fallacies / 3. Question Begging
Question-begging assumes the proposition which is being challenged [PG]
     Full Idea: To beg the question is to take for granted in your argument that very proposition which is being challenged
     From: PG (Db (ideas) [2031])
     A reaction: An undoubted fallacy, and a simple failure to engage in the rational enterprise. I suppose one might give a reason for something, under the mistaken apprehension that it didn't beg the question; analysis of logical form is then needed.
2. Reason / F. Fallacies / 5. Fallacy of Composition
If the parts of the universe are subject to the law of nature, the whole universe must also be subject to it [Cicero]
     Full Idea: If the parts of the universe are subject to the law of nature, then the universe itself must be subject to this law.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.86)
2. Reason / F. Fallacies / 6. Fallacy of Division
What is true of a set is also true of its members [PG]
     Full Idea: The fallacy of division is the claim that what is true of a set must therefore be true of its members.
     From: PG (Db (ideas) [2031])
     A reaction: Clearly a fallacy, but if you only accept sets which are rational, then there is always a reason why a particular is a member of a set, and you can infer facts about particulars from the nature of the set
2. Reason / F. Fallacies / 7. Ad Hominem
The Ad Hominem Fallacy criticises the speaker rather than the argument [PG]
     Full Idea: The Ad Hominem Fallacy is to criticise the person proposing an argument rather than the argument itself, as when you say "You would say that", or "Your behaviour contradicts what you just said".
     From: PG (Db (ideas) [2031])
     A reaction: Nietzsche is very keen on ad hominem arguments, and cheerfully insults great philosophers, but then he doesn't believe there is such a thing as 'pure argument', and he is a relativist.
3. Truth / A. Truth Problems / 1. Truth
There cannot be more than one truth [Cicero]
     Full Idea: There cannot be more than one truth.
     From: M. Tullius Cicero (Academica [c.45 BCE], II.xlviii.147)
3. Truth / H. Deflationary Truth / 3. Minimalist Truth
Minimal theories of truth avoid ontological commitment to such things as 'facts' or 'reality' [PG]
     Full Idea: Minimalist theories of truth are those which involve minimum ontological commitment, avoiding references to 'reality' or 'facts' or 'what works', preferring to refer to formal relationships within language.
     From: PG (Db (ideas) [2031])
     A reaction: Personally I am suspicious of minimal theories, which seem to be designed by and for anti-realists. They seem too focused on language, when animals can obviously formulate correct propositions. I'm quite happy with the 'facts', even if that is vague.
5. Theory of Logic / D. Assumptions for Logic / 1. Bivalence
How can the not-true fail to be false, or the not-false fail to be true? [Cicero]
     Full Idea: How can something that is not true not be false, or how can something that is not false not be true?
     From: M. Tullius Cicero (On Fate ('De fato') [c.44 BCE], 16.38)
     A reaction: We must at least distinguish between whether the contrary thing is not actually true, or whether we are prepared to assert that it is not true. The disjunction may seem to be a false dichotomy. 'He isn't good' may not entail 'he is evil'.
5. Theory of Logic / D. Assumptions for Logic / 2. Excluded Middle
Dialectic assumes that all statements are either true or false, but self-referential paradoxes are a big problem [Cicero]
     Full Idea: It is a fundamental principle of dialectic that every statement is either true or false. So is this a true proposition or a false one: "If you say that you are lying and say it truly, you lie"?
     From: M. Tullius Cicero (Academica [c.45 BCE], II.xxix.95)
5. Theory of Logic / L. Paradox / 1. Paradox
Monty Hall Dilemma: do you abandon your preference after Monty eliminates one of the rivals? [PG]
     Full Idea: The Monty Hall Dilemma: Three boxes, one with a big prize; pick one to open. Monty Hall then opens one of the other two, which is empty. You may, if you wish, switch from your box to the other unopened box. Should you?
     From: PG (Db (ideas) [2031])
     A reaction: The other two boxes, as a pair, are more likely contain the prize than your box. Monty Hall has eliminated one of them for you, so you should choose the other one. Your intuition that the two remaining boxes are equal is incorrect!
10. Modality / B. Possibility / 6. Probability
Everything has a probability, something will happen, and probabilities add up [PG]
     Full Idea: The three Kolgorov axioms of probability: the probability of an event is a non-negative real number; it is certain that one of the 'elementary events' will occur; and the unity of probabilities is the sum of probability of parts ('additivity').
     From: PG (Db (ideas) [2031])
     A reaction: [My attempt to verbalise them; they are normally expressed in terms of set theory]. Got this from a talk handout, and Wikipedia.
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / a. Naïve realism
If reality is just what we perceive, we would have no need for a sixth sense [PG]
     Full Idea: Reality must be more than merely what we perceive, because a sixth sense would enhance our current knowledge, and a seventh, and so on.
     From: PG (Db (ideas) [2031])
12. Knowledge Sources / A. A Priori Knowledge / 5. A Priori Synthetic
If my team is losing 3-1, I have synthetic a priori knowledge that they need two goals for a draw [PG]
     Full Idea: If my football team is losing 3-1, I seem to have synthetic a priori knowledge that they need two goals to achieve a draw
     From: PG (Db (ideas) [2031])
12. Knowledge Sources / B. Perception / 1. Perception
If we have complete healthy senses, what more could the gods give us? [Cicero]
     Full Idea: If human nature were interrogated by some god as to whether it was content with its own senses in a sound and undamaged state or demanded something better, I cannot see what more it could ask for.
     From: M. Tullius Cicero (Academica [c.45 BCE], II.vii.19)
12. Knowledge Sources / E. Direct Knowledge / 4. Memory
How can there be a memory of what is false? [Cicero]
     Full Idea: How can there possibly be a memory of what is false?
     From: M. Tullius Cicero (Academica [c.45 BCE], II.vii.22)
13. Knowledge Criteria / D. Scepticism / 3. Illusion Scepticism
Every true presentation can have a false one of the same quality [Cicero]
     Full Idea: [The sceptical Academics say] what is false cannot be perceived, but every true presentation is such that there can be a false presentation of the same quality.
     From: M. Tullius Cicero (Academica [c.45 BCE], II.40)
     A reaction: It was the stoics who focused the discussion on 'presentations'. This claim is purely theoretical; no one has ever experienced a false presentation of talking to a family member that was as vivid as the real thing.
15. Nature of Minds / A. Nature of Mind / 2. Psuche
The soul is the heart, or blood in the heart, or part of the brain, of something living in heart or brain, or breath [Cicero]
     Full Idea: Some think the soul is the heart; Empedocles holds that the soul is blood in the heart; others said one part of the brain claimed the primacy of soul; others say the heart or brain are habitations of the soul; while others identify soul and breath.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.ix.17-19)
     A reaction: A nice survey of views. Note that many of them identify the psuché/anima with physical parts of the body; only the fourth option seems to be dualist. This is despite the contemptuous response to Democritus' atomist theory of soul.
15. Nature of Minds / A. Nature of Mind / 5. Unity of Mind
How can one mind perceive so many dissimilar sensations? [Cicero]
     Full Idea: Why is it that, using the same mind, we have perception of things so utterly unlike as colour, taste, heat, smell and sound?
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xx.47)
     A reaction: This leaves us with the 'binding problem', of how the dissimilar sensations are pulled together into one field of experience. It is a nice simple objection, though, to anyone who simplistically claims that the mind is self-evidently unified.
The soul has a single nature, so it cannot be divided, and hence it cannot perish [Cicero]
     Full Idea: In souls there is no mingling of ingredients, nothing of two-fold nature, so it is impossible for the soul to be divided; impossible, therefore, for it to perish either; for perishing is like the separation of parts which were maintained in union.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xxix.71)
     A reaction: Cicero knows he is pushing his luck in asserting that perishing is a sort of division. Why can't something be there one moment and gone the next? He appears to be in close agreement with Descartes about being a 'thinking thing'.
16. Persons / C. Self-Awareness / 3. Limits of Introspection
Like the eye, the soul has no power to see itself, but sees other things [Cicero]
     Full Idea: The soul has not the power of itself to see itself, but, like the eye, the soul, though it does not see itself, yet discerns other things.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xxvii)
     A reaction: The soul is a complex item which contributes many layers of interpretation to what it sees, so there is scope for parts of the soul seeing other parts. Somewhere in the middle Cicero seems to be right - there is an elusive something we can't get at.
16. Persons / F. Free Will / 6. Determinism / a. Determinism
Whoever knows future causes knows everything that will be [Cicero]
     Full Idea: Whoever grasps the causes of future things must necessarily grasp all that will be.
     From: M. Tullius Cicero (On Divination ('De divinatione') [c.46 BCE], 1.127)
     A reaction: Laplace stated this idea in terms of Newtonian physics (Idea 3441), but the key idea is stated more simply and clearly here. God can know the future in this way, without actually seeing it happen now. I can't think why it should not be true.
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
Why would mind mix with matter if it didn't need it? [Cicero]
     Full Idea: If the gods have no need of the sensible world, why mix up mind with water and water with mind, if mind can exist by itself without any need of matter?
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.24)
     A reaction: This question migrates into our puzzles about why a separate mental substance would be produced by evolution. If it is device physical systems use to promote themselves, mental substance is reduced to an inferior and dependent role.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / a. Physicalism critique
Souls contain no properties of elements, and elements contain no properties of souls [Cicero]
     Full Idea: No beginnings of souls can be found on earth; there is no combination in souls that could be born from earth, nothing that partakes of moist or airy or fiery; for in those elements there is nothing to possess the power of memory, thought, or reflection.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], I.xxvi.66)
     A reaction: Interesting, but I think magnetism is an instructive analogy, which has weird properties which we never perceive in elements (though it is there, buried deep - suggesting panpsychism). Cicero would be disconcerted to find that fire isn't an element.
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / b. Multiple realisability
Maybe a mollusc's brain events for pain ARE of the same type (broadly) as a human's [PG]
     Full Idea: To defend type-type identity against the multiple realisability objection, we might say that a molluscs's brain events that register pain ARE of the same type as humans, given that being 'of the same type' is a fairly flexible concept.
     From: PG (Db (ideas) [2031])
     A reaction: But this reduces 'of the same type' to such vagueness that it may become vacuous. You would be left with token-token identity, where the mental event is just identical to some brain event, with its 'type' being irrelevant.
Maybe a frog's brain events for fear are functionally like ours, but not phenomenally [PG]
     Full Idea: To defend type-type identity against the multiple realisability objection, we might (also) say that while a frog's brain events for fear are functionally identical to a human's (it runs away), that doesn't mean they are phenomenally identical.
     From: PG (Db (ideas) [2031])
     A reaction: I take this to be the key reply to the multiple realisability problem. If a frog flees from a loud noise, it is 'frightened' in a functional sense, but that still leaves the question 'What's it like to be a frightened frog?', which may differ from humans.
19. Language / B. Reference / 1. Reference theories
The Electra: she knows this man, but not that he is her brother [Eucleides, by Diog. Laertius]
     Full Idea: The 'Electra': Electra knows that Orestes is her brother, but not that this man is Orestes, so she knows and does not know her brother simultaneously.
     From: report of Eucleides (fragments/reports [c.410 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Eu.4
     A reaction: Hence we distinguish 'know of', 'know that' and 'know how'. Hence Russell makes 'knowledge by acquaintance' fundamental, and descriptions come later.
19. Language / F. Communication / 1. Rhetoric
Oratory and philosophy are closely allied; orators borrow from philosophy, and ornament it [Cicero]
     Full Idea: There is a close alliance between the orator and the philosophical system of which I am a follower, since the orator borrows subtlely from the Academy, and repays the loan by giving to it a copious and flowing style and rhetorical ornament.
     From: M. Tullius Cicero (On Fate ('De fato') [c.44 BCE], 02.03)
     A reaction: It is a misundertanding to think that rhetoric and philosophy are seen as in necessary opposition. Philosophers just seemed to think that oratory works a lot better if it is truthful.
Eloquence educates, exhorts, comforts, distracts and unites us, and raises us from savagery [Cicero]
     Full Idea: How wonderful is the power of eloquence! It enables us to learn and to teach. We use it to exhort and persuade, to comfort the unfortunate, to distract the timid and calm the passionate. It unites us in law and society, and raises us from savagery.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], 2.147)
     A reaction: [compressed] Cicero would have been well aware of the doubts about rhetoric felt by Socrates (and possibly Plato). Cicero was probably the greatest Roman orator.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / g. Moral responsibility
If desire is not in our power then neither are choices, so we should not be praised or punished [Cicero]
     Full Idea: If the cause of desire is not situated within us, even desire itself is also not in our power. ...It follows that neither assent nor action is in our power. Hence there is no justice in either praise or blame, either honours or punishments.
     From: M. Tullius Cicero (On Fate ('De fato') [c.44 BCE], 17.40)
     A reaction: This is the view of 'old philosophers', but I'm unsure which ones. Cicero spurns this view. It is obvious that the causes of our desires are largely out of our control. Responsibility seems to concern what we do about our desires.
22. Metaethics / C. The Good / 1. Goodness / b. Types of good
The chief good is unity, sometimes seen as prudence, or God, or intellect [Eucleides]
     Full Idea: The chief good is unity, which is known by several names, for at one time people call it prudence, at another time God, at another intellect, and so on.
     From: Eucleides (fragments/reports [c.410 BCE]), quoted by Diogenes Laertius - Lives of Eminent Philosophers 02.9.2
     A reaction: So the chief good is what unites and focuses our moral actions. Kant calls that 'the will'.
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / c. Motivation for virtue
Virtues must be very detached, to avoid being motivated by pleasure [Cicero]
     Full Idea: None of the virtues can exist unless they are disinterested, for virtue driven to duty by pleasure as a sort of pay is not virtue at all but a deceptive sham and pretence of virtue.
     From: M. Tullius Cicero (Academica [c.45 BCE], II.xlvi.140)
23. Ethics / C. Virtue Theory / 3. Virtues / f. Compassion
We should not share the distress of others, but simply try to relieve it [Cicero]
     Full Idea: We ought not to share distresses ourselves for the sake of others, but we ought to relieve others of their distress if we can.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], IV.xxvi.56)
     A reaction: This strikes me as a sensible and balanced attitude. Some people, particularly in a Christian culture, urge that feeling strong and painful compassion for others is an intrinsic good, but the commonsense view is that that just increases human suffering.
23. Ethics / C. Virtue Theory / 4. External Goods / c. Wealth
All men except philosophers fear poverty [Cicero]
     Full Idea: All men are afraid of poverty, but not a single philosopher is so.
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], V.xxxi.88)
     A reaction: Not a thought which is encountered very often in modern philosophy journals. If a person is to be 'philosophical' in the way they live, calm endurance of the vicissitudes and hardships of life has to be a key prerequisite.
23. Ethics / D. Deontological Ethics / 3. Universalisability
The essence of propriety is consistency [Cicero]
     Full Idea: The whole essence of propriety is quite certainly consistency.
     From: M. Tullius Cicero (On Duties ('De Officiis') [c.44 BCE], 1.110)
     A reaction: This seems to me the key intuition on which Kant built his deontological ethical theory. However, opponents say the consistency requires principles, and these are the enemies of truly good human behaviour, which involves Aristotle's 'particulars'.
23. Ethics / E. Utilitarianism / 4. Unfairness
Utilitarianism seems to justify the discreet murder of unhappy people [PG]
     Full Idea: If I discreetly murdered a gloomy and solitary tramp who was upsetting people in my village, if is hard to see how utilitarianism could demonstrate that I had done something wrong.
     From: PG (Db (ideas) [2031])
24. Political Theory / D. Ideologies / 5. Democracy / f. Against democracy
If one despises illiterate mechanics individually, they are not worth more collectively [Cicero]
     Full Idea: Can anything be more foolish than to suppose that those, whom individually one despises as illiterate mechanics, are worth anything collectively?
     From: M. Tullius Cicero (Tusculan Disputations [c.44 BCE], V.xxxvi.104)
     A reaction: Aristotle disagrees (Idea 2823). In 1906 a huge number of people guessed the weight of a cow at a fair, and the average was within one pound of the truth. In our world the healthy workings of the group are warped by the mass media.
25. Social Practice / D. Justice / 3. Punishment / c. Deterrence of crime
We have the death penalty, but still have thousands of robbers [Cicero]
     Full Idea: We have robbers by the thousand, although they have the penalty of death before their eyes.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.86)
26. Natural Theory / A. Speculations on Nature / 1. Nature
Some regard nature simply as an irrational force that imparts movement [Cicero]
     Full Idea: Some regard nature as an irrational force which merely imparts a mechanical motion to material bodies.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.81)
27. Natural Reality / G. Biology / 2. Life
Life is Movement, Respiration, Sensation, Nutrition, Excretion, Reproduction, Growth (MRS NERG) [PG]
     Full Idea: The biologists' acronym for the necessary conditions of life is MRS NERG: that is, Movement, Respiration, Sensation, Nutrition, Excretion, Reproduction, Growth.
     From: PG (Db (ideas) [2031])
     A reaction: How strictly necessary are each of these is a point for discussion. A notorious problem case is fire, which (at a stretch) may pass all seven tests.
28. God / A. Divine Nature / 4. Divine Contradictions
An omniscient being couldn't know it was omniscient, as that requires information from beyond its scope of knowledge [PG]
     Full Idea: God seems to be in the paradoxical situation that He may be omniscient, but can never know that He is, because that involves knowing that there is nothing outside his scope of knowledge (e.g. another God)
     From: PG (Db (ideas) [2031])
Why shouldn't the gods fear their own destruction? [Cicero]
     Full Idea: Why should the gods not be apprehensive of their own possible dissolution?
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.114)
How could God know there wasn't an unknown force controlling his 'free' will? [PG]
     Full Idea: How could God be certain that he has free will (if He has), if He couldn't be sure that there wasn't an unknown force controlling his will?
     From: PG (Db (ideas) [2031])
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
I wonder whether loss of reverence for the gods would mean the end of all virtue [Cicero]
     Full Idea: I do not know whether, if our reverence for the gods were lost, we should not also see the end of good faith, of human brotherhood, and even of justice itself, which is the keystone of all the virtues.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.3)
28. God / A. Divine Nature / 6. Divine Morality / d. God decrees morality
God doesn't obey the laws of nature; they are subject to the law of God [Cicero]
     Full Idea: God is not subject to obey the laws of nature. It is nature that is subject to the laws of God.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.77)
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
It seems clear to me that we have an innate idea of the divine [Cicero]
     Full Idea: Let us take it as agreed that we have a preconception or "an innate idea" (as I have called it) or a prior knowledge of the divine.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.44)
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
Many primitive people know nothing of the gods [Cicero]
     Full Idea: There must be many wild and primitive peoples who have no idea of the gods at all.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.62)
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
If a person cannot feel the power of God when looking at the stars, they are probably incapable of feeling [Cicero]
     Full Idea: If any man cannot feel the power of God when he looks upon the stars, then I doubt whether he is capable of any feeling at all.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.55)
It is obvious from order that someone is in charge, as when we visit a gymnasium [Cicero]
     Full Idea: If one comes into a gymnasium and sees everything properly arranged and carried on in order, one does not imagine these arrangements to be accidental, but infers that there is someone in command whose orders are obeyed.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.15)
If the barbarians of Britain saw a complex machine, they would be baffled, but would know it was designed [Cicero]
     Full Idea: If someone were to take the celestial globe of Posidonius and show it to the people of Britain, would a single one of those barbarians fail to see that it was the product of a conscious intelligence?
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.88)
Chance is no more likely to create the world than spilling lots of letters is likely to create a famous poem [Cicero]
     Full Idea: If someone thinks chance made the world, he should also think that if an infinite number of the letters of the alphabet were shaken together and poured out on the ground it would be possible for them to spell out the whole 'Annals' of Ennius.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], II.93)
28. God / B. Proving God / 3. Proofs of Evidence / c. Teleological Proof critique
If everything with regular movement and order is divine, then recurrent illnesses must be divine [Cicero]
     Full Idea: Are we to find a divinity in every regular movement and in everything which happens in a constant order? If so, we shall have to say that tertian and quartan agues are divine because their course and recurrence is absolutely uniform.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], III.24)
28. God / C. Attitudes to God / 1. Monotheism
Either the gods are identical, or one is more beautiful than another [Cicero]
     Full Idea: Are the gods all exactly the same? If not, then one must be more beautiful than another.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.80)
28. God / C. Attitudes to God / 4. God Reflects Humanity
The gods are happy, so virtuous, so rational, so must have human shape [Cicero]
     Full Idea: We agree the gods are happy, and no happiness is possible without virtue: there is no virtue without reason: and reason is associated only with the human form: then it must follow that the gods themselves have human shape.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.48)
28. God / C. Attitudes to God / 5. Atheism
Why believe in gods if you have never seen them? [Cicero]
     Full Idea: Did you ever actually see a god? Then why do you believe that gods exist?
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], I.88)
29. Religion / D. Religious Issues / 3. Problem of Evil / a. Problem of Evil
The lists of good men who have suffered and bad men who have prospered are endless [Cicero]
     Full Idea: Time would fail me if I tried to list all the good men for whom things have turned out badly. So it would if I tried to mention all the wicked who have prospered.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], III.80)
29. Religion / D. Religious Issues / 3. Problem of Evil / b. Human Evil
The gods blame men for having vices, but they could have given us enough reason to avoid them [Cicero]
     Full Idea: You gods say that the fault lies in the vices of mankind. But you could have endowed men with reason in a form which would exclude all vice and crime.
     From: M. Tullius Cicero (On the Nature of the Gods ('De natura deorum') [c.44 BCE], III.76)
