Our duty, as men and women, is to proceed as if limits to our ability did not exist. We are collaborators in creation.
We are raised to believe (on the surface, at least) that us humans only have so much love to give, and that it comes in a standard round unit: one. After all, we associate love with the heart, and, well, you've either got a whole heart, or you're dead, period. You can't, common wisdom goes, just run around dividing that one heart up freely; to claim to do so means that you're either a fool, or you're dividing up something that is dead.
There are men so incorrigibly lazy that no inducement that you can offer will tempt them to work; so eaten up by vice that virtue is abhorrent to them, and so inveterately dishonest that theft is to them a master passion. When a human being has reached that stage, there is only one course that can be rationally pursued. Sorrowfully, but remorselessly, it must be recognized that he has become lunatic, morally demented, incapable of self-government, and that upon him, therefore, must be passed the sentence of permanent seclusion from a world in which he is not fit to be at large.
