And we have to remember that in this way the law of the State is, as a matter of fact, perpetually operating upon every one of us. We are often liable to suppose that it is only active in relation to those people against whom it is definitely set in motion; but it does operate in the life of every one of the citizens of a community; because the fact that certain actions would involve us in State-penalty most undoubtedly does keep all of us from indulging in those actions at certain times, even though at calm moments we recognise that it would be wrong to do so. Trivial instances are nearly always the clearest. Most of us, I suppose, are sufficiently honest to desire in general terms to pay for what we buy; and we should perhaps usually pay for our places in the train, even if there were no ticket-inspector; still, the existence of the inspector just clinches the matter.[#] The possibility of the penalty as a matter of fact helps to maintain our general, permanent, and deliberate purpose of honesty against a momentary temptation to be dishonest; and so far it is helping us to live up to our purpose, or, in other words, is increasing our real freedom. In fact, one main test of good legislation is precisely whether it does or does not in this way develop real freedom by increasing people’s power to live by their own deliberate purpose. [#] I owe the illustration to Mr. A. L. Smith, of Balliol. Now so far we have been considering Society as consisting of relatively free persons (though the freedom exists in varying degrees, both as regards the external constraint and capacity for self-control), these persons having various claims which have to be regulated by the justice which the State upholds; in other words, in this stage, we are regarding justice in the way in which I suppose it is most usually regarded, namely, as rendering to a man what is due to him. That is the definition with which Plato in _The Republic_ starts his enquiry, and he naturally found very soon that it would not work.[#] It will not work because the moral values of people are not determinable. You cannot, as a matter of fact, ever say what is the relative weight of the various claims that may be made on behalf of this or that man. Most particularly there is the perpetual conflict between the actual and the potential worth of any men. [#] He appropriately puts it in the mouth of Polemarchus, the well-brought up, but wholly inexperienced, young man.
