8 ideas

7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
Pure supervenience explains nothing, and is a sign of something fundamental we don't know [Nagel]
     Full Idea: Pure, unexplained supervenience is never a solution to a problem but a sign that there is something fundamental we don't know.
     From: Thomas Nagel (The Psychophysical Nexus [2000], §III)
     A reaction: This seems right. It is not a theory or an explanation, merely the observation of a correlation which will require explanation. Why are they correlated?
8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence
The substantial form is the principle of action or the primitive force of acting [Leibniz]
     Full Idea: The substantial form is the principle of action or the primitive force of acting.
     From: Gottfried Leibniz (De Mundo Praesenti [1686], A6.4.1507-8), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 3
     A reaction: The clearest statement of the modification of Aristotle's hylomorphism which Leibniz preferred in his middle period, and which strikes me as an improvement, and about right. Shame that monads got too much of a grip on him, but he was trying to dig deeper.
9. Objects / D. Essence of Objects / 1. Essences of Objects
A true being must (unlike a chain) have united parts, with a substantial form as its subject [Leibniz]
     Full Idea: In a Being one per se a real union is required consisting not in the situation or motion of parts, as in a chain or a house, but in a unique individual principle and subject of attributes and operations, in us a soul and in a body a substantial form.
     From: Gottfried Leibniz (De Mundo Praesenti [1686], A6.4.1506), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 7
     A reaction: Leibniz is said not to be an essentialist, by making all properties essential, but he is certainly committed to substance, and it sounds like essence here (or one view of essence), when it makes identity possible. This idea is pure Aristotle.
10. Modality / B. Possibility / 6. Probability
Truth-functional possibilities include the irrelevant, which is a mistake [Edgington]
     Full Idea: How likely is a fair die landing on an even number to land six? My approach is, assume an even number, so three possibilities, one a six, so 'one third'; the truth-functional approach is it's true if it is not-even or six, so 'two-thirds'.
     From: Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 3)
     A reaction: The point is that in the truth-functional approach, if the die lands not-even, then the conditional comes out as true, when she says it should be irrelevant. She seems to be right about this.
10. Modality / B. Possibility / 8. Conditionals / a. Conditionals
It is a mistake to think that conditionals are statements about how the world is [Edgington]
     Full Idea: The mistake philosophers have made, in trying to understand the conditional, is to assume that its function is to make a statement about how the world is (or how other possible worlds are related to it), true or false, as the case may be.
     From: Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 1)
     A reaction: 'If pigs could fly we would never catch them' may not be about the world, but 'if you press this switch the light comes on' seems to be. Actually even the first one is about the world. I've an inkling that Edgington is wrong about this. Powers!
10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals
A conditional does not have truth conditions [Edgington]
     Full Idea: A conditional does not have truth conditions.
     From: Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 1)
X believes 'if A, B' to the extent that A & B is more likely than A & ¬B [Edgington]
     Full Idea: X believes that if A, B, to the extent that he judges that A & B is nearly as likely as A, or (roughly equivalently) to the extent that he judges A & B to be more likely than A & ¬B.
     From: Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 5)
     A reaction: This is a formal statement of her theory of conditionals.
10. Modality / B. Possibility / 8. Conditionals / e. Supposition conditionals
Conditionals express what would be the outcome, given some supposition [Edgington]
     Full Idea: It is often necessary to suppose (or assume) that some epistemic possibility is true, and to consider what else would be the case, or would be likely to be the case, given this supposition. The conditional expresses the outcome of such thought processes.
     From: Dorothy Edgington (Do Conditionals Have Truth Conditions? [1986], 1)
     A reaction: This is the basic Edgington view. It seems to involve an active thought process, and imagination, rather than being the static semantic relations offered by possible worlds analyses. True conditionals state relationships in the world.
