Actuality proves possibility, but that doesn't explain how it is possible [Inwagen]
10. Modality / D. Knowledge of Modality / 1. A Priori Necessary
Kripke separates necessary and a priori, proposing necessary a posteriori and contingent a priori examples [Kripke, by O'Grady]
A priori = Necessary because we imagine all worlds, and we know without looking at actuality? [Kripke]

A priori truths can be known independently of experience - but they don't have to be [Kripke]
12. Knowledge Sources / A. A Priori Knowledge / 8. A Priori as Analytic

Kripke says pain is necessarily pain, but a brain state isn't necessarily painful [Kripke, by Rey]
Identity must be necessary, but pain isn't necessarily a brain state, so they aren't identical [Kripke, by Schwartz,SP]

19. Language / B. Reference / 3. Direct Reference / c. Social reference
Kripke makes reference a largely social matter, external to the mind of the speaker [Kripke, by McGinn]

20. Action / C. Motives for Action / 5. Action Dilemmas / b. Double Effect
A 'double effect' is a foreseen but not desired side-effect, which may be forgivable [Foot]
The doctrine of double effect can excuse an outcome because it wasn't directly intended [Foot]
Double effect says foreseeing you will kill someone is not the same as intending it [Foot]
Without double effect, bad men can make us do evil by threatening something worse [Foot]
Double effect seems to rely on a distinction between what we do and what we allow [Foot]

Abortion is puzzling because we do and don't want the unborn child to have rights [Foot]
26. Natural Theory / B. Natural Kinds / 5. Reference to Natural Kinds

One's mental and other life is centred on the brain, unlike any other part of the body [Inwagen]
At the lower level, life trails off into mere molecular interaction [Inwagen]
Being part of an organism's life is a matter of degree, and vague [Inwagen]
A flame is like a life, but not nearly so well individuated [Inwagen]
A tumour may spread a sort of life, but it is not a life, or an organism [Inwagen]
