     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)

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]

     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]

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)

     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)

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]

     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]

     From: PG (Db (lexicon) [c.1001 BCE], 92)

1. Philosophy / D. Nature of Philosophy / 1. Philosophy
Philosophy is a priori if it is anything [Bonjour]
     Full Idea: My conviction is that philosophy is a priori if it is anything.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], Pref)
     A reaction: How about knowledge of a posteriori necessities, such as the length of a metre, known by observation of the standard metre in Paris?
1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
Philosophy is like a statue which is worshipped but never advances [Bacon]
     Full Idea: Philosophy and the intellectual sciences stand like statues, worshipped and celebrated, but not moved or advanced.
     From: Francis Bacon (Preface to Great Instauration (Renewal) [1620], Vol.4.14), quoted by Robert Fogelin - Walking the Tightrope of Reason Ch.5
     A reaction: Still the view of most scientists, I suspect. Personally I disagree, because I think philosophy has made enormous advances, in accurate analysis of arguments. The trouble is there is so much of it that it is hard to discern, and we don't live long enough.
1. Philosophy / E. Nature of Metaphysics / 1. Nature of Metaphysics
Metaphysics is the best knowledge, because it is the simplest [Bacon]
     Full Idea: That knowledge is worthiest which is charged with least multiplicity, which appeareth to be metaphysic
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.6)
     A reaction: A surprising view, coming from the father of modern science, but essentially correct. Obviously metaphysics aspires to avoid multiplicity, but it is riddled not only with complexity in its researches, but massive uncertainties.
1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
Natural history supports physical knowledge, which supports metaphysical knowledge [Bacon]
     Full Idea: Knowledges are as pyramides, whereof history is the basis. So of natural philosophy, the basis is natural history, the stage next the basis is physic; the stage next the vertical point is metaphysic.
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.6)
     A reaction: The father of modern science keeps a place for metaphysics, as the most abstract level above the physical sciences. I would say he is right. It leads to my own slogan: science is the servant of philosophy.
1. Philosophy / E. Nature of Metaphysics / 5. Metaphysics beyond Science
Physics studies transitory matter; metaphysics what is abstracted and necessary [Bacon]
     Full Idea: Physic should contemplate that which is inherent in matter, and therefore transitory; and metaphysic that which is abstracted and fixed
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.3)
     A reaction: He cites the ancients for this view, with which he agrees. One could do worse than hang onto metaphysics as the study of necessities, but must then face the attacks of the Quineans - that knowledge of necessities is beyond us.
Physics is of material and efficient causes, metaphysics of formal and final causes [Bacon]
     Full Idea: Physic inquireth and handleth the material and efficient causes; and metaphysic handleth the formal and final causes.
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.3)
     A reaction: Compare Idea 12119. This divides up Aristotle's famous Four Causes (or Explanations), outlined in 'Physics' II.3. The concept of 'matter', and the nature of 'cause' seem to me to fall with the purview of metaphysics. Interesting, though.
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 / A. Nature of Reason / 3. Pure Reason
Perceiving necessary connections is the essence of reasoning [Bonjour]
     Full Idea: If one never in fact grasps any necessary connections between anything, it is hard to see what reasoning could possible amount to.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.3)
2. Reason / A. Nature of Reason / 6. Coherence
Coherence can't be validated by appeal to coherence [Bonjour]
     Full Idea: The epistemic authority of coherence cannot itself be established by appeal to coherence.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7 n50)
     A reaction: The standard approach amongs modern philosophers (following, I think, Kripke) is to insist on 'intuition' as basic, despite all its problems. I have no better suggestion.
For any given area, there seem to be a huge number of possible coherent systems of beliefs [Bonjour]
     Full Idea: The 2nd standard objection to coherence is 'alternative coherent systems' - that there will be indefinitely many possible systems of belief in relation to any given subject area, each as internally coherent as the others.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2)
     A reaction: This seems to imply that you could just invent an explanation, as long as it was coherent, but presumably good coherence is highly sensitive to the actual evidence. Bonjour observes that many of these systems would not survive over time.
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 / 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 / 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 / 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!
5. Theory of Logic / L. Paradox / 4. Paradoxes in Logic / e. The Lottery paradox
The Lottery Paradox says each ticket is likely to lose, so there probably won't be a winner [Bonjour, by PG]
     Full Idea: The Lottery Paradox says that for 100 tickets and one winner, each ticket has a .99 likelihood of defeat, so they are all likely to lose, so there is unlikely to be a winner.
     From: report of Laurence Bonjour (Externalist Theories of Empirical Knowledge [1980], §5) by PG - Db (ideas)
     A reaction: The problem seems to be viewing each ticket in isolation. If I buy two tickets, I increase my chances of winning.
8. Modes of Existence / E. Nominalism / 1. Nominalism / a. Nominalism
Only individual bodies exist [Bacon]
     Full Idea: Nothing truly exists in nature beyond individual bodies.
     From: Francis Bacon (The New Organon [1620]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 182
     A reaction: [Unusually, Pasnau gives no reference in the text; possibly II:1-2] What this leaves out, from even an auster nominalist ontology, is undifferentiated stuff like water. Even electrons don't seem quite distinct from one another.
9. Objects / C. Structure of Objects / 2. Hylomorphism / c. Form as causal
In hylomorphism all the explanation of actions is in the form, and the matter doesn't do anything [Bacon]
     Full Idea: Prime, common matter seems to be a kind of accessory and to stand as a substratum, whereas any kind of action seems to be a mere emanation of form. So it is that forms are given all the leading parts.
     From: Francis Bacon (Philosophical Studies 1611-19 [1617], p.206), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 07.2
     A reaction: This is a very striking criticism of hylomorphism. The revolution was simple - that actually matter seems to do all the real work, and the form can take a back seat.
There are only individual bodies containing law-based powers, and the Forms are these laws [Bacon]
     Full Idea: Though nothing exists in nature except individual bodies which exhibit pure individual acts [powers] in accordance with law…It is this law and its clauses which we understand by the term Forms.
     From: Francis Bacon (The New Organon [1620], p.103), quoted by Jan-Erik Jones - Real Essence §3
     A reaction: This isn't far off what Aristotle had in mind, when he talks of forms as being 'principles', though there is more emphasis on mechanisms in the original idea. Note that Bacon takes laws so literally that he refers to their 'clauses'.
10. Modality / B. Possibility / 1. Possibility
The concept of possibility is prior to that of necessity [Bonjour]
     Full Idea: While necessity and possibility are interdefinable concepts, it is the idea of a possible world or situation which is intuitively primary.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §1.3)
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 / A. Knowledge / 1. Knowledge
The concept of knowledge is so confused that it is best avoided [Bonjour]
     Full Idea: The concept of knowledge is seriously problematic in more than one way, and is best avoided as far as possible in sober epistemological discussion.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 1.5)
     A reaction: Two sorts of states seem to be conflated: one where an animal has a true belief caused by an environmental event, and the other where a scholar pores over books and experiments to arrive at a hard-won truth. I say only the second is 'knowledge'.
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 / 2. Self-Evidence
It is hard to give the concept of 'self-evident' a clear and defensible characterization [Bonjour]
     Full Idea: Foundationalists find it difficult to attach a clear and defensible content to the idea that basic beliefs that are characterized as 'self-justified' or 'self-evident'.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 1.4)
     A reaction: A little surprising from a fan of a priori foundations, especially given that 'self-evident' is common usage, and not just philosophers' jargon. I think we can talk of self-evidence without a precise definition. We talk of an 'ocean' without trouble.
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
The senses deceive, but also show their own errors [Bacon]
     Full Idea: It is certain that the senses deceive, but they also testify to their own errors.
     From: Francis Bacon (Preface to Great Instauration (Renewal) [1620], p.32), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 22.1
     A reaction: Nice. This is the empiricist view, rather than the rationalist line that reason sorts out the mess created by the senses. Most people know things if you just show them.
12. Knowledge Sources / B. Perception / 8. Adverbial Theory
The adverbial account will still be needed when a mind apprehends its sense-data [Bonjour]
     Full Idea: The adverbial account of the content of experience is almost certainly correct, because no account can be given of the relation between sense-data and the apprehending mind that is independent of the adverbial theory.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 5.1 n3)
     A reaction: This boils down to the usual objection to sense-data, which is 'cut out the middle man'. Bonjour is right that at some point the mind has finally to experience whatever is coming in, and it must experience it in a particular way.
12. Knowledge Sources / C. Rationalism / 1. Rationalism
Our rules of thought can only be judged by pure rational insight [Bonjour]
     Full Idea: Criteria or rules do not somehow apply to themselves. They must be judged by the sort of rational insight or intuition that the rationalist is advocating.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §5.2)
Moderate rationalists believe in fallible a priori justification [Bonjour]
     Full Idea: Moderate rationalism preserves a priori justification, but rejects the idea that it is infallible.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.1)
12. Knowledge Sources / D. Empiricism / 1. Empiricism
We don't assume there is no land, because we can only see sea [Bacon]
     Full Idea: They are ill discoverers that think there is no land, when they can see nothing but sea.
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.5)
     A reaction: Just the sort of pithy remark for which Bacon is famous. It is an obvious point, but a nice corrective to anyone who wants to apply empirical principles in a rather gormless way.
Empiricists are collecting ants; rationalists are spinning spiders; and bees do both [Bacon]
     Full Idea: Empiricists are like ants; they collect and put to use; but rationalists, like spiders, spin threads out of themselves. (…and bees follow the middle way, of collecting material and transforming it).
     From: Francis Bacon (Cogitata et Visa [1607])
     A reaction: Nice (and so concisely expressed). Bees seem to be just more intelligent and energetic empiricists.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / a. Foundationalism
Externalist theories of knowledge are one species of foundationalism [Bonjour]
     Full Idea: Externalist theories of knowledge are one species of foundationalism.
     From: Laurence Bonjour (Externalist Theories of Empirical Knowledge [1980], Intro)
     A reaction: I don't see why there shouldn't be a phenomenalist, anti-realist version of externalism, which just has 'starting points' instead of a serious commitment to foundations.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / b. Basic beliefs
The big problem for foundationalism is to explain how basic beliefs are possible [Bonjour]
     Full Idea: The fundamental question that must be answered by any acceptable version of foundationalism is: how are basic beliefs possible?
     From: Laurence Bonjour (Externalist Theories of Empirical Knowledge [1980], §I)
     A reaction: This question seems to be asking for a justification for basic beliefs, which smacks of 'Who made God?' Look, basic beliefs are just basic, right?
Conscious states have built-in awareness of content, so we know if a conceptual description of it is correct [Bonjour]
     Full Idea: If we describe a non-conceptual conscious state, we are aware of its character via the constitutive or 'built-in' awareness of content without need for a conceptual description, and so recognise that a conceptually formulated belief about it is correct.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 4.3)
     A reaction: This is Bonjour working very hard to find an account of primitive sense experiences which will enable them to function as 'basic beliefs' for foundations, without being too thin to do anything, or too thick to be basic. I'm not convinced.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / d. Rational foundations
A priori justification requires understanding but no experience [Bonjour]
     Full Idea: A proposition will count as being justified a priori as long as no appeal to experience is needed for the proposition to be justified - once it is understood.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §1.2)
     A reaction: Could you 'understand' that a square cannot be circular without appeal to experience? I'm losing faith in the pure a priori.
You can't explain away a priori justification as analyticity, and you can't totally give it up [Bonjour]
     Full Idea: Moderate empiricists try unsuccessfully to explain a priori justification by means of analyticity, and radical empiricist attempts to dispense with a priori justification end in nearly total scepticism.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.1)
     A reaction: My working theory is neither of the above. Because we can abstract from the physical world, we can directly see/experience generalised (and even necessary) truths about it.
A priori justification can vary in degree [Bonjour]
     Full Idea: A priori justification can vary in degree.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.5)
     A reaction: This idea, which I trace back at least to Russell, seems to me one of breakthrough ideas in modern thought. It means that a priori knowledge can be reconnected with a posteriori knowledge.
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / e. Pro-foundations
The main argument for foundationalism is that all other theories involve a regress leading to scepticism [Bonjour]
     Full Idea: The central argument for foundationalism is simply that all other possible outcomes of the regress of justifications lead inexorably to scepticism.
     From: Laurence Bonjour (Externalist Theories of Empirical Knowledge [1980], §I)
     A reaction: If you prefer coherence to foundations, you need the security of reason to assess the coherence (which seems to be an internal foundation!).
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
The induction problem blocks any attempted proof of physical statements [Bonjour]
     Full Idea: The attempt to prove physical statements on the basis of sensory evidence is defeated by the problem of induction.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.6)
     A reaction: This sounds like a logician's use of the word 'prove', which would be a pretty forlorn hope. Insofar as experience proves anything, fully sensing a chair proves its existence.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
A coherence theory of justification can combine with a correspondence theory of truth [Bonjour]
     Full Idea: There is no manifest absurdity in combining a coherence theory of justification with a correspondence theory of truth.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 5.1)
     A reaction: His point is to sharply (and correctly) distinguish coherent justification from a coherence theory of truth. Personally I would recommend talking of a 'robust' theory of truth, without tricky commitment to 'correspondence' between very dissimilar things.
There will always be a vast number of equally coherent but rival systems [Bonjour]
     Full Idea: On any plausible conception of coherence, there will always be many, probably infinitely many, different and incompatible systems of belief which are equally coherent.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 5.5)
     A reaction: If 'infinitely many' theories are allowed, that blocks the coherentist hope that widening and precisifying the system will narrow down the options and offer some verisimilitude. If we stick to current English expression, that should keep them finite.
Empirical coherence must attribute reliability to spontaneous experience [Bonjour]
     Full Idea: An empirical coherence theory needs, for the beliefs of a cognitive system to be even candidates for empirical justification, that the system must contain laws attributing a high degree of reliability to a variety of spontaneous cognitive beliefs.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 7.1)
     A reaction: Wanting such a 'law' seems optimistic, and not in the spirit of true coherentism, which can individually evaluate each experiential belief. I'm not sure Bonjour's Observation Requirement is needed, since it is incoherent to neglect observations.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / b. Pro-coherentism
A well written novel cannot possibly match a real belief system for coherence [Bonjour]
     Full Idea: It is not even minimally plausible that a well written novel ...would have the degree of coherence required to be a serious alternative to anyone's actual system of beliefs.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 5.5)
     A reaction: This seems correct. 'Bleak House' is wonderfully consistent, but its elements are entirely verbal, and nothing occupies the space between the facts that are described. And Lady Dedlock is not in Debrett. I think this kills a standard objection.
The objection that a negated system is equally coherent assume that coherence is consistency [Bonjour]
     Full Idea: Sometimes it is said that if one has an appropriately coherent system, an alternative system can be produced simply be negating all of the components of the first system. This would only be so if coherence amounted simply to consistency.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 5.5)
     A reaction: I associate Russell with this original objection to coherentism. I formerly took this to be a serious problem, and am now relieved to see that it clearly isn't.
A coherent system can be justified with initial beliefs lacking all credibility [Bonjour]
     Full Idea: It is simply not necessary in order for [the coherence] view to yield justification to suppose that cognitively spontaneous beliefs have some degree of initial or independent credibility.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 7.2)
     A reaction: This is thoroughly and rather persuasively criticised by Erik Olson. But he always focuses on the coherence of a 'system' with multiple beliefs. I take the credibility of each individual belief to need coherent assessment against a full background.
The best explanation of coherent observations is they are caused by and correspond to reality [Bonjour]
     Full Idea: The best explanation for a stable system of beliefs which rely on observation is that the beliefs are caused by what they depict, and the system roughly corresponds to the independent reality it describes.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 8.3)
     A reaction: [compressed] Anyone who links best explanation to coherence (and to induction) warms the cockles of my heart. Erik Olson offers a critique, but doesn't convince me. The alternative is to find a better explanation (than reality), or give up.
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / c. Coherentism critique
My incoherent beliefs about art should not undermine my very coherent beliefs about physics [Bonjour]
     Full Idea: If coherentism is construed as involving the believer's entire body of beliefs, that would imply, most implausibly, that the justification of a belief in one area (physics) could be undermined by serious incoherence in another area (art history).
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.1)
     A reaction: Bonjour suggests that a moderated coherentism is needed to avoid this rather serious problem. It is hard to see how a precise specification could be given of 'areas' and 'local coherence'. An idiot about art would inspire little confidence on physics.
Coherence seems to justify empirical beliefs about externals when there is no external input [Bonjour]
     Full Idea: The 1st standard objection to coherence is the 'isolation problem', that contingent apparently-empirical beliefs might be justified in the absence of any informational input from the extra-conceptual world they attempt to describe.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2)
     A reaction: False beliefs can be well justified. In a perfect virtual reality we would believe our experiences precisely because they were so coherent. Messengers from the front line have top priority, but how do you detect infiltrators and liars?
Coherentists must give a reason why coherent justification is likely to lead to the truth [Bonjour]
     Full Idea: The 3rd standard objection to coherence is the demand for a meta-justification for coherence, a reason for thinking that justification on the basis of the coherentist view of justification is in fact likely to lead to believing the truth.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 3.2)
     A reaction: Some coherentists respond by adopting a coherence theory of truth, which strikes me as extremely unwise. There must be an underlying optimistic view, centred on the principle of sufficient reason, that reality itself is coherent. I like Idea 8618.
13. Knowledge Criteria / C. External Justification / 1. External Justification
Extreme externalism says no more justification is required than the truth of the belief [Bonjour]
     Full Idea: The most extreme version of externalism would be one that held that the external condition required for justification is simply the truth of the belief in question.
     From: Laurence Bonjour (Externalist Theories of Empirical Knowledge [1980], §II)
     A reaction: The question is, why should we demand any more than this? The problem case is, traditionally, the lucky guess, but naturalist may say that these just don't occur with any regularity. We only get beliefs right because they are true.
Externalist theories of justification don't require believers to have reasons for their beliefs [Bonjour]
     Full Idea: An externalist theory of epistemic justification or warrant need not involve the possession by the believer of anything like a reason for thinking that their belief is true.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7)
     A reaction: That is the problem with externalism. If the believer does not have a reason, then why would they believe? Externalists are interesting on justification, but daft about belief. Why do I believe I know something, when I can't recall how I learnt it?
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / a. Reliable knowledge
Reliabilists disagree over whether some further requirement is needed to produce knowledge [Bonjour]
     Full Idea: Reliabilist views differ among themselves with regard to whether a belief's being produced in a reliable way is by itself sufficient for epistemic justification or whether there are further requirements that must be satisfied as well.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 2.1)
     A reaction: If 'further requirements' are needed, the crucial question would be which one is trumps when they clash. If the further requirements can correct the reliable source, then it cannot any longer be called 'reliabilism'. It's Further-requirement-ism.
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / b. Anti-reliabilism
External reliability is not enough, if the internal state of the believer is known to be irrational [Bonjour]
     Full Idea: External or objective reliability is not enough to offset subjective irrationality (such as unexplained clairvoyance).
     From: Laurence Bonjour (Externalist Theories of Empirical Knowledge [1980], §IV)
     A reaction: A good argument. Where do animals fit into this? If your clairvoyance kept working, in the end you might concede that you 'knew', even though you were baffled about how you managed it.
If the reliable facts producing a belief are unknown to me, my belief is not rational or responsible [Bonjour]
     Full Idea: How can the fact that a belief is reliably produced make my acceptance of that belief rational and responsible when that fact itself is entirely unavailable to me?
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 2.2)
     A reaction: This question must rival Pollock's proposal (Idea 8815) as the master argument against externalism. Bonjour is assuming that knowledge has to be 'rational and responsible', but clearly externalists take a more lax view of knowledge.
13. Knowledge Criteria / C. External Justification / 10. Anti External Justification
Even if there is no obvious irrationality, it may be irrational to base knowledge entirely on external criteria [Bonjour]
     Full Idea: It may be that where there are no positive grounds for a charge of irrationality, the acceptance of a belief with only external justification is still subjectively irrational in a sense that rules out its being epistemologically justified.
     From: Laurence Bonjour (Externalist Theories of Empirical Knowledge [1980], §IV)
     A reaction: A key objection. Surely rational behaviour requires a judgement to be made before a belief is accepted? If you are consistently clairvoyant, you must ask why.
Externalism means we have no reason to believe, which is strong scepticism [Bonjour]
     Full Idea: If externalism is the final story, we have no reason to think that any of our beliefs are true, which amounts to a very strong and intuitively implausible version of scepticism.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7)
     A reaction: A very good point. I may, like a cat, know many things, with good external support, but as soon as I ask sceptical questions, I sink without trace if I lack internal reasons.
14. Science / A. Basis of Science / 3. Experiment
Science moves up and down between inventions of causes, and experiments [Bacon]
     Full Idea: All true and fruitful natural philosophy hath a double scale or ladder, ascendent and descendent, ascending from experiments to the invention of causes, and descending from causes to the invention of new experiments.
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.1)
     A reaction: After several hundred years, I doubt whether anyone can come up with a better account of scientific method than Bacon's.
Nature is revealed when we put it under pressure rather than observe it [Bacon]
     Full Idea: The secrets of nature reveal themselves more readily under the vexations of art than when they go their own way.
     From: Francis Bacon (Preface to Great Instauration (Renewal) [1620], Vol.4.95), quoted by Robert Fogelin - Walking the Tightrope of Reason Ch.5
     A reaction: This is a splendid slogan for the dawn of the age of science, and pinpoints the reason why we have advanced so much further than the Greeks. You can, of course, overdo the 'vexations of art'. It also justifies the critical approach to philosophy.
14. Science / A. Basis of Science / 5. Anomalies
Anomalies challenge the claim that the basic explanations are actually basic [Bonjour]
     Full Idea: The distinctive significance of anomalies lies in the fact that they undermine the claim of the allegedly basic explanatory principles to be genuinely basic.
     From: Laurence Bonjour (The Structure of Empirical Knowledge [1985], 5.3)
     A reaction: This seems plausible, suggesting that (rather than an anomaly flatly 'falsifying' a theory) an anomaly may just demand a restructuring or reconceptualising of the theory.
14. Science / B. Scientific Theories / 2. Aim of Science
Science must clear away the idols of the mind if they are ever going to find the truth [Bacon]
     Full Idea: We must clear away the idols and false notions which are now in possession of the human understanding, and have taken deep root therein, and so beset men's minds that truth can hardly find an entrance.
     From: Francis Bacon (The New Organon [1620], 38), quoted by Mark Wrathall - Heidegger: how to read 2
     A reaction: [He goes on to list the types of idol]
14. Science / B. Scientific Theories / 5. Commensurability
Many different theories will fit the observed facts [Bacon]
     Full Idea: The ordinary face and view of experience is many times satisfied by several theories and philosophies.
     From: Francis Bacon (The Advancement of Learning [1605], II.VIII.5)
     A reaction: He gives as his example that the Copernican system and the Ptolemaic system both seem to satisfy all the facts. He wrote in 1605, just before Galileo's telescope. His point is regularly made in modern discussions. In this case, he was wrong!
14. Science / C. Induction / 2. Aims of Induction
Induction must go beyond the evidence, in order to explain why the evidence occurred [Bonjour]
     Full Idea: Inductive explanations must be conceived of as something stronger than mere Humean constant conjunction; …anything less than this will not explain why the inductive evidence occurred in the first place.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §7.7)
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
If neither the first-level nor the second-level is itself conscious, there seems to be no consciousness present [Bonjour]
     Full Idea: In the higher-order thought theory of consciousness, if the first-order thought is not itself conscious and the second-order thought is not itself conscious, then there seems to be no consciousness of the first-level content present at all.
     From: Laurence Bonjour (A Version of Internalist Foundationalism [2003], 4.2)
     A reaction: A nice basic question. The only plausible answer seems to be that consciousness arises out of the combination of levels. Otherwise one of the levels is redundant, or we are facing a regress.
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
People love (unfortunately) extreme generality, rather than particular knowledge [Bacon]
     Full Idea: It is the nature of the mind of man (to the extreme prejudice of knowledge) to delight in the spacious liberty of generalities, as in a champaign region, and not in the inclosures of particularity.
     From: Francis Bacon (The Advancement of Learning [1605], II.VIII.1)
     A reaction: I have to plead guilty to this myself. He may have pinpointed the key motivation behind philosophy. We all want to know things, as Aristotle said, but some of us want the broad brush, and others want the fine detail.
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.
18. Thought / C. Content / 1. Content
All thought represents either properties or indexicals [Bonjour]
     Full Idea: I assume that the contents of thought can be accounted for by appeal to just two general sorts of ingredient - properties (including relations) and indexicals.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §6.7)
     A reaction: I don't accept that relations are a type of properties. Since he does not include objects or substances, I take it that he considers objects to be bundles of properties.
19. Language / F. Communication / 6. Interpreting Language / b. Indeterminate translation
Indeterminacy of translation is actually indeterminacy of meaning and belief [Bonjour]
     Full Idea: The thesis of the indeterminacy of translation would be better described as the thesis of the indeterminacy of meaning and belief.
     From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.5)
     A reaction: Not necessarily. It is not incoherent to believe that the target people have a coherent and stable system of meaning and belief, but finding its translation indeterminate because it is holistic, and rooted in a way of life.
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])
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / c. Purpose denied
Teleological accounts are fine in metaphysics, but they stop us from searching for the causes [Bacon]
     Full Idea: To say 'leaves are for protecting of fruit', or that 'clouds are for watering the earth', is well inquired and collected in metaphysic, but in physic they are impertinent. They are hindrances, and the search of the physical causes hath been neglected.
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.7)
     A reaction: This is the standard rebellion against Aristotle which gave rise to the birth of modern science. The story has been complicated by natural selection, which bestows a sort of purpose on living things. Nowadays we pursue both paths.
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / a. Greek matter
Stripped and passive matter is just a human invention [Bacon]
     Full Idea: Stripped and passive matter seems nothing more than an invention of the human mind.
     From: Francis Bacon (Philosophical Studies 1611-19 [1617], p.206), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 07.2
     A reaction: Bacon seems to me to get too little credit in the history of philosophy, because he is just seen as a progenitor of science. His modern views predate most radical 17th C thought by 20 years.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
Essences are part of first philosophy, but as part of nature, not part of logic [Bacon]
     Full Idea: I assign to summary philosophy the operation of essences (as quantity, similitude, diversity, possibility), with this distinction - that they be handled as they have efficacy in nature, and not logically.
     From: Francis Bacon (The Advancement of Learning [1605], II.VII.3)
     A reaction: I take this to be a splendid motto for scientific essentialism, in a climate where modal logicians appear to have taken over the driving seat in our understanding of essences.
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
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])
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])
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
Even without religion, there are many guides to morality [Bacon]
     Full Idea: Atheism leaves a man to sense, to philosophy, to natural piety, to laws, to reputation; all which may be guides to an outward moral virtue, though religion were not.
     From: Francis Bacon (17: Of Superstition [1625], p.52)
     A reaction: One might add to Bacon's list 'contracts', or 'rational consistency', or 'self-evident human excellence', or 'natural sympathy'. This is a striking idea, which clearly made churchmen uneasy when atheism began to spread.
