I, for one, am a man of passions, capable of and liable to do rather foolish things for which I sometimes feel rather sorry. I do often find myself speaking or acting somewhat too quickly when it would be better to wait more patiently. I think that other people may also sometimes do similar foolish things. Now that being so, what’s to be done, must one consider oneself a dangerous man, incapable of anything at all? I don’t think so. But it’s a matter of trying by every means to turn even these passions to good account. For example, to name one passion among others, I have a more or less irresistible passion for books, and I have a need continually to educate myself, to study, if you like, precisely as I need to eat my bread.
