Explicative and ampliative reasoning. Laplace and Mill on induction. Distinction between uniformity (what does happen) and law (what was compelled to happen). Criticism of Laplace's treatment of probability. CSP's views correspond to those of Venn, but derived independently. The notion of "equally possible." (Cf. "objective probability" in Venn, Logic of Chance, 1866.) CSP gives 1864 as the year he arrived at his conception of probability.
