You see only the productions of second-rate folk who are in a hurry to get wealth and fame. The true knowledge, the deadly knowledge, is still kept secret. But, believe me, my friend, it is there.
I believe everything out of the common. The only thing to distrust is the normal.
Every man at the bottom of his heart believes that he is a born detective.
I believe that every man has in his soul a passion for treasure-hunting, which will often drive a coward into prodigies of valour.
I believe that all wisdom consists in caring immensely for a few right things, and not caring a straw about the rest.
