Two times two is five is sometimes also a most charming little thing.

But man is a frivolous and unseemly being, and perhaps, similar to a chess player, likes only the process of achieving the goal, but not the goal itself. And who knows (one cannot vouch for it), perhaps the whole goal mankind strives for on earth consists just in this ceaselessness of the process of achievement alone, that is to say, in life itself, and not essentially in the goal, which, of course, is bound to be nothing other than two times two is four--that is, a formula; and two times two is four is no longer life, gentlemen, but the beginning of death. At least man has always somehow feared this two times two is four, and I fear it even now. Suppose all man ever does is search for this two times two is four; he crosses oceans, he sacrifices his life in the search; but to search it out, actually to find it--by God, he's somehow afraid. For he senses that once he finds it, there will be nothing to search for. Workers, when they're done working, at least get their pay, go to a pot-house, then wind up with the police--so it keeps them busy for a week. But where is man to go? Something awkward, at any rate, can be noticed in him each time he achieves some such goal. Achieving he likes, but having achieved he does not quite like, and that, of course, is terribly funny. In short, man is comically arranged, there is apparently a joke in all this. But still, two times two is four is a most obnoxious thing. Two times two is four--why, in my opinion, it's sheer impudence, sirs. Two times two is four has a cocky look; it stands across your path, arms akimbo, and spits. I agree that two times two is four is an excellent thing; but if we're going to start praising everything, then two times two is five is sometimes also a most charming little thing.
