5 ideas

4. Formal Logic / E. Nonclassical Logics / 11. Dynamic Logics

15381	Dyamic logics model changes between classical states, in action, belief, and computing [Uckelman]
	Full Idea: Dynamic logic gives versions of propositional, modal and predicate logics, in which the states are classical, but changes of assignments between states can be expressed, by modelling action, knowledge and belief change, and compute programs.
	From: Sara L. Uckelman (Dynamic Logics [2010])
	A reaction: [compressed]

7. Existence / A. Nature of Existence / 6. Criterion for Existence

3534	To be is to have causal powers [Alexander,S]
	Full Idea: To be is to have causal powers.
	From: Samuel Alexander (works [1927], §4), quoted by Jaegwon Kim - Nonreductivist troubles with ment.causation
	A reaction: This is sometimes called Alexander's Principle. It is first found in Plato, and is popular with physicalists, but there are problem cases... A thing needs to exist in order to have causal powers. To exist is more than to be perceived.

13. Knowledge Criteria / D. Scepticism / 1. Scepticism

3061	Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius]
	Full Idea: Anaxarchus said that he was not even sure that he knew nothing.
	From: report of Anaxarchus (fragments/reports [c.340 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.10.1

17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism

3398	Epiphenomenalism makes the mind totally pointless [Alexander,S]
	Full Idea: Epiphenomenalism supposes something to exist in nature which has nothing to do and no purpose to serve.
	From: Samuel Alexander (works [1927]), quoted by Jaegwon Kim - Philosophy of Mind p.129
	A reaction: An objection, but not, I think, a strong one. The fact, for example, that sweat is shiny is the result of good evolutionary reasons, but I cannot think of any purpose which it serves. All events which are purposeful are likely to have side-effects.

14494	Epiphenomenalism is like a pointless nobleman, kept for show, but soon to be abolished [Alexander,S]
	Full Idea: Epiphenomenalism supposes something to exist in nature which has nothing to do, no purpose to serve, a species of noblesse which depends on the work of its inferiors, but is kept for show and might as well, and undoubtedly would in time be abolished.
	From: Samuel Alexander (Space, Time and Deity (2 vols) [1927], 2:8), quoted by Jaegwon Kim - Nonreductivist troubles with ment.causation IV
	A reaction: Wonderful! Kim quotes this, and labels the implicit slogan (to be real is to have causal powers) 'Alexander's Dictum'. All the examples given of epiphenomena are only causally inert within a defined system, but they act causally outside the system.
