The fencing (for it does not deserve the name of serious disputation) with which Bishop Butler meets his opponents is rendered possible by the laxness with which the words "identical" and "identity" are ordinarily used. Bishop Butler would not seriously deny that personality undergoes great changes between infancy and old age, and hence that it must undergo some change from moment to moment. So universally is this recognised, that it is common to hear it said of such and such a man that he is not at all the person he was, or of such and such another that he is twice the man he used to be--expressions than which none nearer the truth can well be found. On the other hand, those whom Bishop Butler is intending to confute would be the first to admit that, though there are many changes between infancy and old age, yet they come about in any one individual under such circumstances as we are all agreed in considering as the factors of personal identity rather than as hindrances thereto--that is to say that there has been no entire and permanent death on the part of the individual between any two phases of his existence, and that any one phase has had a lasting though perhaps imperceptible effect upon all succeeding ones. So that no one ever seriously argued in the manner supposed by Bishop Butler, unless with modifications and saving clauses, to which it does not suit his purpose to call attention. * * * * * No doubt it would be more strictly accurate to say "you are the now phase of the person I met last night," or "you are the being which has been evolved from the being I met last night," than "you are the person I met last night." But life is too short for the periphrases which would crowd upon us from every quarter, if we did not set our face against all that is under the surface of things, unless, that is to say, the going beneath the surface is, for some special chance of profit, excusable or capable of extenuation. * * * * *
