There are few regions of thought, however, so full of false ideas, as the conception of moral duty towards one’s neighbours and how it is to be fulfilled. Leaving out of consideration, for the moment, the theoretical systems of morality which are based on the maintenance of human society, and which attach less importance to the concrete feelings and motives at the moment of action than to the effect on the general system of morality, we come at once to the popular idea which defines the morality of a man by his “goodness,” the degree to which his compassionate disposition is developed. From the philosophical point of view, Hutcheson, Hume, and Smith saw in sympathy the nature and source of all ethical conduct, and this view received a very strong support from Schopenhauer’s sympathetic morality. Schopenhauer’s “Essay on the Foundations of Morality” shows in its motto “It is easy to preach morality, difficult to find a basis for it,” the fundamental error of the sympathetic ethics which always fails to recognise that the science of ethics is not merely an explanation and description of conduct, but a search for a guide to it. Whoever will be at the pains diligently to listen to the inner voice of man, in order to establish what he ought to do, will certainly reject every system of ethics, the aim of which is to be a doctrine of the requirements which man has invented for himself and others instead of being a relation of what he actually does in furthering these requirements or in stifling them. The object of all moral science is not what is happening but what ought to happen. All attempts to explain ethics by psychology overlook the fact that every psychic event in man is appraised by man himself, and the appraiser of the psychic event cannot be a psychic event. This standard can only be an idea, or a value which is never fully realised, and which cannot be altered by any experience because it remains constant, even if all experience is in opposition to it. Moral conduct can be only conduct controlled by an idea. And so we can choose only from systems of morality which set up some idea or maxim for the regulation of conduct, and there are only two to choose from, the ethical socialism or social ethics, founded by Bentham and Mill, but imported to the Continent and diligently propagated in Germany and Norway, and ethical individualism such as is taught by Christianity and German idealism.
