Note 262 — Chapter XX · (continued 2)

I confess, he says in his logic, that I was born with such a temper, that the chief pleasure I find in study is not from the learning the arguments of others, but by inventing my own. This disposition alone impelled me in youth to the study of science; hence, whenever a new book promised by its title some new discovery, before sitting down to read it, I used to try whether my own natural sagacity could lead me to anything of the kind, and I took care not to lose this innocent pleasure by too hasty a perusal. This answered so often that I at length perceived that I arrived at truth, not as other men do after blind and precarious guesses, by good luck rather than skill, but that long experience had taught me certain fixed rules, which were of surprising utility, and of which I afterwards made use to discover more truths.
