13766 | 'If' is the same as 'given that', so the degrees of belief should conform to probability theory [Ramsey, by Ramsey] |

From: Alfred R. Mele (Springs of Action [1992], p.3), quoted by Rowland Stout - Action 5 'Psychological' | |
A reaction: Stout glosses this as a rather distinctive view, which endorses the causal theory of action (as opposed to citing reasons and justifications for actions). A key debate is whether the psychological inputs really do cause the outputs. |

542 | Fear of the gods was invented to discourage secret sin [Critias] |
