Note 99 — Chapter VII

The practice of judging of the future by the past is sometimes treated as if it were a mere habit of the uncultivated and undisciplined part of mankind—a kind of mental weakness. Undoubtedly, our past experience is not always an infallible guide to what is to be our experience in the future. We often have to correct our past experience, by carefully separating the accidental from the essential; by more comprehensive analysis of the facts which constitute our former experience. But when we have full, comprehensive, and accurate views of that which has happened to us heretofore, our beliefs in what is to happen to us hereafter are not only attained by a safe process of reasoning, but that process is imposed upon us by a law of our mental constitution.
