The art of measuring, as precisely as possible, probabilities of things, with the goal that we would be able always to choose or follow in our judgments and actions that course, which will have been determined to be better, more satisfactory, safer or more advantageous.
— Jacob Bernoulli, Ars Conjectandi (1713)
From Ars Conjectandi (1713), where he defines the art of conjecture.
