identified with Chemistry; seeing that in the photographic process, light becomes a chemical agent. Considering that muscles contract when stimulated by a galvanic current, we ought to treat of Physiology and Electricity as forming one science. Nor should we even distinguish between vegetable and animal life; for these are found to have a common root, and it is hardly possible to say of the lowest organisms which division they belong to. So that unless such objectors are prepared to say that Botany and Zoology should be regarded as one, and that all lines of demarcation between the physical sciences should be abolished, they must in consistency tolerate an analogous classification in moral science; and must admit that whilst this is in a certain sense artificial, it may be an essential preliminary to anything like systematic investigation. The same finite power of comprehension which compels us to deal with natural phenomena by separating them into groups and studying each group by itself, may also compel us to separate those actions which place a man in direct relationship with his fellows, from others which do not so place him; although it may be true that such a separation cannot be strictly maintained. And even in dealing with one of these sections-in developing the principles of right conduct to others, it may be further necessary to distinguish, as above, the primary and most imperative principle, from the secondary and less imperative one; notwithstanding that these have a common root.

§ 4.

The realization of the Divine Idea being reduced to the fulfilment of certain conditions, it becomes the office of a scientific morality, to make a detailed statement of the mode in which life must be regulated so as to conform to them. On each of these axiomatic truths it must be possible to build a series of theorems immediately bearing upon our daily conduct; or, inverting the thought-every act stands in a certain relationship to these truths, and it must be possible in some way or other to solve the problem, whether that relationship is one of accordance or discordance. When such a series of theorems has been elaborated, and solutions have been given to such a series of problems, the task of the moralist is accomplished.

Each of these axioms, however, may have its own set of consequences separately deduced, or indeed, as already hinted, must have them so deduced. Their respective developments constitute independent departments of moral science, requiring to be dealt with in the order of their natural sequence. For the present, therefore, our attention will be confined to the first and most essential of them. Individual or private morality, as distinguished from social or public morality, is not to be entered upon in the following pages. Neither will there be found in them any statement of that class of moral obligations above comprehended under the terms positive and negative beneficence. It is with the several inferences to be drawn from that primary condition to greatest happiness, the observance of which is vaguely signified by the word justice, that we have now to deal. Our work will be to unfold that condition into a system of equity; to mark out those limits put to each man's proper sphere of activity, by the like spheres of other men; to delineate the relationships that are necessitated by a recognition of those limits; or-in other words-to develop the principles of Social Statics.

These other divisions of the subject may be taken up on a future occasion, should circumstances favour.

CHAPTER IV.

DERIVATION OF A FIRST PRINCIPLE.

§ 1.

THERE will possibly be some for whom the à priori considerations set forth in the foregoing chapter, are too abstract for distinct comprehension. It is easy, however, to reason our way to that first principle of ethical science which we are about to follow out to its consequences, without any appeal to these. And it will be desirable now to do this. Starting afresh then, from the admitted truth, that human happiness is the Divine will, let us look at the means appointed for the obtainment of that happiness, and observe what conditions they presuppose.

Happiness is a certain state of consciousness. That state must be produced by the action upon consciousness of certain modifying influences-by certain affections of it. All affections of consciousness we term sensations. And amongst the rest, those affections of it which constitute happiness must be sensations.

But how do we receive sensations? Through what are called faculties. It is certain that a man cannot see without eyes. Equally certain is it that he can experience no impression of any kind, unless he is endowed with some power fitted to take in that impression; that is, a faculty. All the mental states which he calls feelings and ideas, are affections of his consciousness received through the faculties-sensations given to it by them.

There next comes the question-under what circumstances do the faculties yield those sensations of which happiness consists? The reply is-when they are exercised. It is from the activity of one or more of them that all gratification arises. To the healthful performance of each function of mind or
