8 ideas

1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / a. Philosophy as worldly

22101	Philosophy aims to know the truth about the way things are [Aquinas]
	Full Idea: The study of philosophy has as its purpose to know not what people have thought, but rather the truth about the way things are.
	From: Thomas Aquinas (Sententia on 'De Caelo' [1268], I.22.228), quoted by Kretzmann/Stump - Aquinas, Thomas 05
	A reaction: I agree with this deeply unfashionable opinion. Of course, modern investigations must be more sensitive to biases built into language, culture and conceptual schemes. But I am one of those sad old folks who still think truths can be stated.

10. Modality / C. Sources of Modality / 1. Sources of Necessity

9216	Each area of enquiry, and its source, has its own distinctive type of necessity [Fine,K]
	Full Idea: The three sources of necessity - the identity of things, the natural order, and the normative order - have their own peculiar forms of necessity. The three main areas of human enquiry - metaphysics, science and ethics - each has its own necessity.
	From: Kit Fine (The Varieties of Necessity [2002], 6)
	A reaction: I would treat necessity in ethics with caution, if it is not reducible to natural or metaphysical necessity. Fine's proposal is interesting, but I did not find it convincing, especially in its view that metaphysical necessity doesn't intrude into nature.

11. Knowledge Aims / A. Knowledge / 4. Belief / e. Belief holism

18969	How do you distinguish three beliefs from four beliefs or two beliefs? [Quine]
	Full Idea: Suppose I say that I have given up precisely three beliefs since lunch. An over-coarse individuation could reduce the number to two, and an over-fine one could raise it to four.
	From: Willard Quine (Propositional Objects [1965], p.144)
	A reaction: Obviously if you ask how many beliefs I hold, it would be crazy to give a precise answer. But if I search for my cat, I give up my belief that it is in the kitchen, in the lounge and in the bathroom. That's precise enough to be three beliefs, I think.

13. Knowledge Criteria / C. External Justification / 7. Testimony

9214	Unsupported testimony may still be believable [Fine,K]
	Full Idea: I may have good reason to believe some testimony, for example, even though the person providing the testimony has no good reason for saying what he does.
	From: Kit Fine (The Varieties of Necessity [2002], 5)
	A reaction: Thus small children, madmen and dreamers may occasionally get things right without realising it. I take testimony to be merely one more batch of evidence which has to be assessed in building the most coherent picture possible.

19. Language / D. Propositions / 2. Abstract Propositions / a. Propositions as sense

18967	A 'proposition' is said to be the timeless cognitive part of the meaning of a sentence [Quine]
	Full Idea: A 'proposition' is the meaning of a sentence. More precisely, since propositions are supposed to be true or false once and for all, it is the meaning of an eternal sentence. More precisely still, it is the 'cognitive' meaning, involving truth, not poetry.
	From: Willard Quine (Propositional Objects [1965], p.139)
	A reaction: Quine defines this in order to attack it. I equate a proposition with a thought, and take a sentence to be an attempt to express a proposition. I have no idea why they are supposed to be 'timeless'. Philosophers have some very odd ideas.

19. Language / D. Propositions / 6. Propositions Critique

18968	The problem with propositions is their individuation. When do two sentences express one proposition? [Quine]
	Full Idea: The trouble with propositions, as cognitive meanings of eternal sentences, is individuation. Given two eternal sentences, themselves visibly different linguistically, it is not sufficiently clear under when to say that they mean the same proposition.
	From: Willard Quine (Propositional Objects [1965], p.140)
	A reaction: If a group of people agree that two sentences mean the same thing, which happens all the time, I don't see what gives Quine the right to have a philosophical moan about some dubious activity called 'individuation'.

26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism

9215	Causation is easier to disrupt than logic, so metaphysics is part of nature, not vice versa [Fine,K]
	Full Idea: It would be harder to break P-and-Q implying P than the connection between cause and effect. This difference in strictness means it is more plausible that natural necessities include metaphysical necessities, than vice versa.
	From: Kit Fine (The Varieties of Necessity [2002], 6)
	A reaction: I cannot see any a priori grounds for the claim that causation is more easily disrupted than logic. It seems to be based on the strategy of inferring possibilities from what can be imagined, which seems to me to lead to wild misunderstandings.

27. Natural Reality / C. Space / 3. Points in Space

18970	The concept of a 'point' makes no sense without the idea of absolute position [Quine]
	Full Idea: Unless we are prepared to believe that absolute position makes sense, the very idea of a point as an entity in its own right must be rejected as not merely mysterious but absurd.
	From: Willard Quine (Propositional Objects [1965], p.149)
	A reaction: The fact that without absolute position we can only think of 'points' as relative to a conceptual grid doesn't stop the grid from picking out actual locations in space, as shown by latitude and longitude.
