We come a little nearer to a correct view when we define right conduct by the motive or state of mind of the agent. According to this theory, acts inspired by certain emotions are good, and those inspired by certain other emotions are bad. Mystics hold this view, and have accordingly a certain contempt for the letter of the law. Broadly speaking, it would be held that acts inspired by love are good, and those inspired by hate are bad. In practice, I hold this view to be right; but philosophically I regard it as deducible from something more fundamental. All the theories we have hitherto considered are opposed to those which judge the rightness or wrongness of conduct by its consequences. Of these the most famous is the utilitarian philosophy, which maintained that happiness is the good, and that we ought to act so as to maximise the balance of happiness over unhappiness in the world. I should not myself regard happiness as an adequate definition of the good, but I should agree that conduct ought to be judged by its consequences. I do not mean, of course, that in every practical exigency of daily life we should attempt to think out the results of this or that line of conduct, because, if we did, the opportunity for action would often be past before our calculations were finished. But I do mean that the received moral code, in so far as it is taught in education and embodied in public opinion or the criminal law, should be carefully examined in each generation, to see whether it still serves to achieve desirable ends, and, if not, in what respects it needs to be amended. The moral code, in short, like the legal code, should adapt itself to changing circumstances, keeping the public good always as its motive. If so, we have to consider in what the public good consists. According to this view, “right conduct” is not an autonomous concept, but means “conduct calculated to produce desirable results”. It will be right, let us say, to act so as to make people happy and intelligent, but wrong to act so as to make them unhappy and stupid. We have to ask ourselves how we can discover what constitutes the ends of right conduct.
