Men need some kind of external activity, because they are inactive within.

All wanting comes from need, therefore from lack, therefore from suffering.

There are, first of all, two kinds of authors: those who write for the subject's sake, and those who write for writing's sake. The first kind have had thoughts or experiences which seem to them worth communicating, while the second kind need money and consequently write for money.

Money alone is absolutely good, because it is not only a concrete satisfaction of one need in particular; it is an abstract satisfaction of all.
