There are two distinct and contrasting methods of limiting liberty; the first is Prohibition, "thou shalt not," and the second Command, "thou shalt." There is, however, a sort of prohibition that takes the form of a conditional command, and this one needs to bear in mind. It says if you do so-and-so, you must also do soand-so; if, for example, you go to sea with men you employ, you must go in a seaworthy vessel. But the pure command is unconditional; it says, whatever you have done or are doing or want to do, you are to do this, as when the social system, working through the base necessities of base parents and bad laws, sends a child of thirteen into a factory. Prohibition takes one definite thing from the indefinite liberty of a man, but it still leaves him an unbounded choice of actions. He remains free, and you have merely taken a bucketful from the sea of his freedom. But compulsion destroys freedom altogether. In this Utopia of ours there may be many prohibitions, but no indirect compulsions—if one may so contrive it—and few or no commands. As far as I see it now, in this present discussion, I think, indeed, there should be no positive compulsions at all in Utopia, at any rate for the adult Utopian—unless they fall upon him as penalties incurred.
