Far from being the first induction we make, it is one of the last or, at all events, one of those which are latest in attaining strict philosophical accuracy.
Página 149 - Why is a single instance, in some cases, sufficient for a complete induction ; while in others, myriads of concurring instances, without a single exception known or presumed, go such a very little way towards establishing a universal proposition ?

Página 140 - From causes which appear similar, we expect similar effects. This is the sum of all our experimental conclusions. Now it seems evident, that if this conclusion were formed by reason, it would be as perfect at first, and upon one instance, as after ever so long a course of experience : but the case is far otherwise.
