As a quick aside, let me observe that in moments of high emotion. . . . if the next thing you're going to say makes you feel better, then it's probably the wrong thing to say. This is one of the finer maxims that I've discovered in life. And you can have it, since it's been of no use to me.
Labour is the source of all wealth, the political economists assert. And it really is the source -- next to nature, which supplies it with the material that it converts into wealth. But it is even infinitely more than this. It is the prime basic condition for all human existence, and this to such an extent that, in a sense, we have to say that labour created man himself.
