Nor, again, does it help us to adopt the more modern view of Nature, which regards the organic world as exhibiting, not an aggregate of fixed types, but a continuous and gradual process of changing life. For granting that this ‘evolution’--as the name implies--is not merely a process from old to new, but a progress from less to more of certain definite characteristics; it is surely absurd to maintain that we ought _therefore_ to take these characteristics as Ultimate Good, and make it our whole endeavour to accelerate the arrival of an inevitable future. That whatever is to be will be better than what is, we all hope; but there seems to be no more reason for summarily identifying ‘what ought to be’ with ‘what certainly will be,’ than for finding it in ‘what commonly is,’ or ‘what originally was.’ On the whole, it appears to me that no definition that has ever been offered of the Natural exhibits this notion as really capable of furnishing an independent ethical first principle. And no one maintains that ‘natural’ like ‘beautiful’ is a notion that though indefinable is yet clear, being derived from a simple unanalysable impression. Hence I see no way of extracting from it a definite practical criterion of the rightness of actions. § 3. The discussion in the preceding section will have shown that not all the different views that are taken of the ultimate reason for doing what is concluded to be right lead to practically different methods of arriving at this conclusion. Indeed we find that almost any method may be connected with almost any ultimate reason by means of some--often plausible--assumption. Hence arises difficulty in the classification and comparison of ethical systems; since they often appear to have different affinities according as we consider Method or Ultimate Reason. In my treatment of the subject, difference of Method is taken as the paramount consideration: and it is on this account that I have treated the view in which Perfection is taken to be the Ultimate End as a variety of the Intuitionism which determines right conduct by reference to axioms of duty intuitively known; while I have made as marked a separation as possible between Epicureanism or Egoistic Hedonism, and the Universalistic or Benthamite[73] Hedonism to which I propose to restrict the term Utilitarianism.
