“The most important questions of life… are indeed for the most part only problems of probability.”

—  Pierre-Simon Laplace , book Philosophical Essay on Probabilities

Philosophical Essay on Probabilities (1902)
Context: The most important questions of life... are indeed for the most part only problems of probability. Strictly speaking it may even be said that nearly all our knowledge is problematical; and in the small number of things which we are able to know with certainty, even in the mathematical sciences themselves, the principal means for ascertaining truth—induction and analogy—are based on probabilities.<!--p.1
