Closely connected with the conative nature of "ought" is the imperative character it is apt to assume. But, though frequently used imperatively, "ought" is not necessarily and essentially imperative. Even if the "ought" which I address to myself, in a figurative sense, may be styled a command, it is hardly appropriate to speak of a present command with reference to past actions. The common phrase, "You ought to have done this, or that," cannot be called a command. The conation expressed in "ought" is determined by the idea that the mode of conduct which ought to be performed is not, or will possibly not be, performed. It is also this idea of its not being performed that determines the emotion which gives to "ought" the character of a moral predicate. The doing of what ought not to be done, or the omission of what ought not to be omitted, is apt to call forth moral indignation--this is the most essential fact involved in the notion of "ought." Every "ought"-judgment contains implicitly a negation. Nobody would ever have dreamt of laying down a moral rule if the idea of its transgression had not presented itself to his mind. We may reverse the words of the Apostle,[10] and say that where no transgression is, there is no law. When Solon was asked why he had specified no punishment for one who had murdered a father, he replied that he supposed it could not occur to any man to commit such a crime.[11] Similarly, the modern Shintoist concludes that the primæval Japanese were pure and holy from the fact that they are represented as a people who had no moral commandments.[12] It is this prohibitive character of "ought" that has imparted to duty that idea of antagonism to inclination which has found its most famous expression {136} in the Kantian ethics, and which made Bentham look upon the word itself as having in it "something disagreeable and repulsive."[13] It is the intrinsic connection between "ought" and "wrong" that has given to duty the most prominent place in ethical speculation whenever moral pessimism has been predominant. Whilst the ancient Greeks, with whom happiness was the state of nature, never spoke of duty, but held virtue to be the Supreme Good, Christianity, on the other hand, which looked upon man as a being born and bred in sin, regarded morals pre-eminently as the science of duty. Then, again, in modern times, Kant's categorical imperative came as a reaction against that moral optimism which once more had given the preference to virtue, considering everything in the world or in humanity as beautiful and good from the very beginning.[14] It is also worth noting that the feeling of self-complacency connected with the consciousness of having acted in accordance with the law of duty, has no distinctively expressive name in ordinary language, while the opposite feeling is known by so familiar and distinctive a term as "remorse." This is not, as has been said,[15] "a significant indication of the moral condition
