5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
'¬', '&', and 'v' are truth functions: the truth of the compound is fixed by the truth of the components [Jackson]
8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence
My formal unifying atoms are substantial forms, which are forces like appetites [Leibniz]
I call Aristotle's entelechies 'primitive forces', which originate activity [Leibniz]
9. Objects / A. Existence of Objects / 5. Simples
The analysis of things leads to atoms of substance, which found both composition and action [Leibniz]
9. Objects / B. Unity of Objects / 2. Substance / c. Types of substance
Substance must necessarily involve progress and change [Leibniz]
10. Modality / B. Possibility / 8. Conditionals / b. Types of conditional
Possible worlds for subjunctives (and dispositions), and no-truth for indicatives? [Jackson]
10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
Modus ponens requires that A→B is F when A is T and B is F [Jackson]
When A and B have the same truth value, A→B is true, because A→A is a logical truth [Jackson]
(A&B)→A is a logical truth, even if antecedent false and consequent true, so it is T if A is F and B is T [Jackson]
10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals
In the possible worlds account of conditionals, modus ponens and modus tollens are validated [Jackson]
Only assertions have truth-values, and conditionals are not proper assertions [Jackson]
Possible worlds account, unlike A⊃B, says nothing about when A is false [Jackson]
10. Modality / B. Possibility / 8. Conditionals / f. Pragmatics of conditionals
We can't insist that A is relevant to B, as conditionals can express lack of relevance [Jackson]
20. Action / B. Preliminaries of Action / 1. Intention to Act / a. Nature of intentions
An intending is a judgement that the action is desirable [Davidson]
20. Action / B. Preliminaries of Action / 1. Intention to Act / c. Reducing intentions
Davidson gave up reductive accounts of intention, and said it was a primitive [Davidson, by Wilson/Schpall]
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
We need the metaphysical notion of force to explain mechanics, and not just extended mass [Leibniz]
