1. _Logic_ is the science of the formal laws of thought, and is concerned not with the truth of phenomena, but merely with the laws of correct reasoning about them. Ethics establishes the laws according to which we ought to act. Logic legislates for the reason, and decerns the laws which the intellect must obey if it would think correctly. Both sciences determine what is valid; but while Logic is confined to the realm of what is valid in reasoning, Ethics is occupied with what is valid in action. There is, indeed, a logic of life; and in so far as all true conduct must have a rational element in it and be guided by certain intelligible forms, Ethics may be described as a kind of logic of character. 2. The connection between Ethics and _Aesthetics_ is closer. Aesthetics is the science of the laws of beauty, while Ethics is the science of the laws of the good. But in so far as Aesthetics deals with the emotions rather than the reason it comes into contact with Ethics in the psychological field. In its narrower sense Aesthetics deals with beauty merely in an impersonal way; and its immediate object is not what is morally beautiful, but rather that which is beautiful in itself irrespective of moral considerations. Ethics, on the other hand, is concerned with personal worth as expressed in perfection of will and action. Conduct may be beautiful and character may afford Aesthetic satisfaction, but Ethics, in so far as it is concerned with judgments of virtue, is independent of all thought of the mere beauty or utility of conduct. Aesthetic consideration may indeed aid practical morality, but it is not identical with it. It is conceivable that what is right may not be immediately beautiful, and may indeed in its pursuit or realisation involve action which contradicts our ideas of beauty. But though both sciences have different aims they are occupied largely with the same emotions, and are connected by a common idealising purpose. In the deepest sense, what is good is beautiful and what is beautiful is good; and {16} ultimately, in the moral and spiritual life, goodness and beauty coincide. Indeed, so close is the connection between the two conceptions that the Greeks used the same word, _to kalon_, to express beauty of form and nobility of character. And even in modern times the expression 'a beautiful soul,' indicates the intimate relation between inner excellence of life and outward attractiveness. Both Aesthetics and Ethics have regard to that symmetry or proportion of life which fulfils our ideas at once of goodness and of beauty. In this sense Schiller sought to remove the sharpness of Kant's moral theory by claiming a place in the moral life for beauty. Our actions are, indeed, good when we do our duty because we ought, but they are beautiful when we do it because we cannot do otherwise, because they have become our second nature. The purpose of all culture, says Schiller, is to harmonise reason and sense, and thus
