4 ideas

2. Reason / D. Definition / 1. Definitions

15927	Definition just needs negation, known variables, conjunction, disjunction, substitution and quantification [Weyl, by Lavine]
	Full Idea: For mathematics, Weyl arrived (by 1917) at a satisfactory list of definition principles: negation, identification of variables, conjunction, disjunction, substitution of constants, and existential quantification over the domain.
	From: report of Hermann Weyl (works [1917]) by Shaughan Lavine - Understanding the Infinite V.3
	A reaction: Lavine summarises this as 'first-order logic with parameters'.

13. Knowledge Criteria / E. Relativism / 2. Knowledge as Convention

1556	By nature people are close to one another, but culture drives them apart [Hippias]
	Full Idea: I regard you all as relatives - by nature, not by convention. By nature like is akin to like, but convention is a tyrant over humankind and often constrains people to act contrary to nature.
	From: Hippias (fragments/reports [c.430 BCE]), quoted by Plato - Protagoras 337c8

20. Action / A. Definition of Action / 1. Action Theory

20062	If a desire leads to a satisfactory result by an odd route, the causal theory looks wrong [Chisholm]
	Full Idea: If someone wants to kill his uncle to inherit a fortune, and having this desire makes him so agitated that he loses control of his car and kills a pedestrian, who turns out to be his uncle, the conditions of the causal theory seem to be satisfied.
	From: Roderick Chisholm (Freedom and Action [1966]), quoted by Rowland Stout - Action 6 'Deviant'
	A reaction: This line of argument has undermined all sorts of causal theories that were fashionable in the 1960s and 70s. Explanation should lead to understanding, but a deviant causal chain doesn't explain the outcome. The causal theory can be tightened.

20. Action / B. Preliminaries of Action / 2. Willed Action / c. Agent causation

20054	There has to be a brain event which is not caused by another event, but by the agent [Chisholm]
	Full Idea: There must be some event A, presumably some cerebral event, which is not caused by any other event, but by the agent.
	From: Roderick Chisholm (Freedom and Action [1966], p.20), quoted by Rowland Stout - Action 4 'Agent'
	A reaction: I'm afraid this thought strikes me as quaintly ridiculous. What kind of metaphysics can allow causation outside the natural nexus, yet occuring within the physical brain? This is a relic of religious dualism. Let it go.
