§ 3.

Objection may be taken to the foregoing classification of the conditions needful to greatest happiness, as being in some degree artificial. It will perhaps be said that the distinction between justice and beneficence cannot be maintained, for that the two graduate into each other imperceptibly. Some may argue that it is not allowable to assume any essential difference between right conduct towards others and right conduct towards self, seeing that what are generally considered purely private actions, do eventually affect others to such a degree, as to render them public actions; as witness the collateral effects of drunkenness or suicide. Others again may contend that all morality should be classed as private; because with the rightly-constituted or moral man, correct conduct to others is merely incidental upon the fulfilment of his own nature.

In each of these allegations there is much truth; and it is not to be denied that under a final analysis, all such distinctions as those above made must disappear. But it should be borne in mind that similar criticisms may be passed upon all classifications whatever. It might after the same fashion be argued that we ought not to separate the laws of heat from those of mechanics, because fire when applied to water generates mechanical force. On like grounds Optics ought to be Edition: current; Page: [71] 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.
