One further point! We have been careful, in dealing with the common-sense concept of self, to distinguish its three aspects, philosophical, practical, scientific; but _we have drawn the limits of this self more strictly than everyday usage warrants_; and we must now correct that error. Common sense, as we remarked on p. 2, is likely to confuse the Me with the Mine, and the Him with the His; the self is extended from personality to possessions. The confusion of Him and His is a natural consequence of the practical reference of the concept; the easiest way to rate or estimate another person is to consider his property, his sphere of influence, his social prominence; and these things, which are a part of the other person’s value, thus become for us a part of himself. The confusion of Me with Mine has a different origin. Intellect, temperament and character are based upon habits, and habits imply an habitual surroundings; we are ‘not ourselves’ when we leave our accustomed groove. No doubt, each of these sources of confusion intermingles with the other; we are not concerned, however, to follow them in detail. § 74. =The Persistence of the Self.=—A full account of the self of common sense, in so far as this self calls for psychological treatment, belongs to social and not to general psychology; and the discussion therefore falls outside the scope of the present book. We must, however, say a word about that _observed continuity of memory and conduct_ which the concept of self, on its philosophical side, professes to explain (p. 308); for the notion of the =persistence of the self= has had a marked influence, as we shall see in § 75, upon this chapter of general psychology. _We are all of us disposed to take the persistence of the self for granted._ Do I not now remember what I did and thought and felt when I was a small child? and do I not now act in accordance with my character, as family and friends expect me to act? Surely the thing is obvious: the organism is physically continuous, from infancy to old age; a likeness of interest, of skill, of aptitudes, may be traced from childhood to manhood; and the discovery of the ‘general common factor’ in the intellectual sphere only confirms what we knew before. The child becomes the adult, and the adult passes into senility, while the self remains the same,—growing and developing and shrinking, to be sure, but essentially unchanged throughout. _That is the natural view_; and for the most part it goes unchallenged.
