The Methods of Ethics : Book III-Book IV (Illustrated)

In offering to the public a new book upon a subject so trite as Ethics, it seems desirable to indicate clearly at the outset its plan and purpose. Its distinctive characteristics may be first given negatively. It is not, in the main, metaphysical or psychological: at the same time it is not dogmatic or directly practical: it does not deal, except by way of illustration, with the history of ethical thought: in a sense it might be said to be not even critical, since it is only quite incidentally that it offers any criticism of the systems of individual moralists. It claims to be an examination, at once expository and critical, of the different methods of obtaining reasoned convictions as to what ought to be done which are to be found—either explicit or implicit—in the moral consciousness of mankind generally: and which, from time to time, have been developed, either singly or in combination, by individual thinkers, and worked up into the systems now historical.
