within the subjective sphere of experience? So, too, why should the moral law command less obedience because it forms part of our own nature? Far from being a danger, ethical subjectivism seems to me more likely to be an acquisition for moral practice. {20} Could it be brought home to people that there is no absolute standard in morality, they would perhaps be somewhat more tolerant in their judgments, and more apt to listen to the voice of reason. If the right has an objective existence, the moral consciousness has certainly been playing at blindman's buff ever since it was born, and will continue to do so until the extinction of the human race. But who does admit this? The popular mind is always inclined to believe that it possesses the knowledge of what _is_ right and wrong, and to regard public opinion as the reliable guide of conduct. We have, indeed, no reason to regret that there are men who rebel against the established rules of morality; it is more deplorable that the rebels are so few, and that, consequently, the old rules change so slowly. Far above the vulgar idea that the right is a settled something to which everybody has to adjust his opinions, rises the conviction that it has its existence in each individual mind, capable of any expansion, proclaiming its own right to exist, and, if need be, venturing to make a stand against the whole world. Such a conviction makes for progress. CHAPTER II THE NATURE OF THE MORAL EMOTIONS IN the preceding chapter it was asserted, in general terms, that the moral concepts are based on emotions, and the leading arguments to the contrary were met. We shall now proceed to examine the nature of the moral emotions. These emotions are of two kinds: disapproval, or indignation, and approval. They have in common characteristics which make them moral emotions, in distinction from others of a non-moral character, but at the same time both of them belong to a wider class of emotions, which I call retributive emotions. Again, they differ from each other in points which make each of them allied to certain non-moral retributive emotions, disapproval to anger and revenge, and approval to that kind of retributive kindly emotion which in its most developed form is gratitude. They may thus, on the one hand, be regarded as two distinct divisions of the moral emotions, whilst, on the other hand, disapproval, like anger and revenge, forms a sub-species of resentment, and approval, like gratitude, forms a sub-species of retributive kindly emotion. The following diagram will help to elucidate the matter:--
