In the Introduction to his famous Théorie Analytique des Probabilités, Laplace, after an eloquent summary of the progress of Astronomy from the days when every rare celestial phenomenon was regarded as a portent of human misery, to the verification in April 1759 of the perihelion passage of Halley's Comet, proceeds to say :—
“The regularity which Astronomy shows us in the movement of Comets exists, beyond doubt, in every phenomenon of nature. The curve described by a simple molecule of air or of vapour is regulated in a manner as certain as the planetary orbits: there is no difference between the two cases save our ignorance.

page 424 note 1 Notwithstanding that we find in this passage, laid down with admirable clearness, the fundamental principles on which Venn builds his Logic of Chance, Boole did not cast himself loose from the traditional view of the foundations of the mathematical theory of probability. This is clear from the passages that immediately precede nud follow. Still, the fact that he wrote the above, and that he questioned the general applicability of the rules of Inverse Probability, entitles him to rank among those who prepared the way to the sounder views that now seem destined to prevail.

page 436 note 1 This for clearness; there is of course, according to our view, no such thing as “indirect” probability
