To determine the exact date at which an intelligent use of the first person appears, is much less easy than it looks. The ‘I’ is apt to appear momentarily and then disappear, as when M. at the age of nineteen months three weeks was observed to say ‘I did’ once, though she did not use ‘I’ again until some time afterwards. Allowing for these difficulties it may be said with some degree of confidence that the great transition from ‘baby’ to ‘I’ is wont to take place in favourable cases early in the first half of the third year. Thus among the dates assigned by different observers I find, twenty-four months, twenty-five months (cases given by Preyer), between twenty-five and twenty-six (Pollock), twenty-seven months (the boy C.). A lady friend tells me that her boy began to use ‘I’ at twenty-four months. In the case of a certain number of precocious children this point is attained at an earlier date. Thus Preyer quotes a case of a child speaking in the first person at twenty months. Schultze gives a case at nineteen months. A friend of mine, a Professor of English Literature, whose boy showed great precocity in sentence-building, reports that he used the forms ‘me’ and ‘I’ within the sixteenth month. Preyer’s boy, on the other hand, who was evidently somewhat slow in lingual development, first used the form of the first person ‘to me’ (mir) at the age of twenty-nine months. The precise way in which these pronominal forms first appear is very curious. Many children use ‘me’ before ‘I’. Preyer’s boy appears to have first used the form ‘to me’ (mir). ‘My’ too is apt to appear among the earliest forms. In such different ways does the child pass to the new and difficult region of pronominal speech. The meaning of this transition has given rise to much discussion. It is plain, to begin with, that a child cannot acquire these forms as he acquires the name ‘papa,’ ‘nurse,’ by a direct and comparatively mechanical mode of imitation. When he does imitate in this fashion he produces, as we have seen, the absurdity of speaking of himself as ‘you’. Hence during the first year or so of speech he makes no use of these forms. He speaks of himself as ‘baby’ or some equivalent name, others coming down to his level and setting him the example. The transition seems to be due in part, as I have elsewhere pointed out, to a growing self-consciousness, to a clearer singling out of the _ego_ or self as the centre of thought and activity, and the understanding of the other ‘persons’ in relation to this centre. Not that self-consciousness _begins_ with the use of ‘I’. The child has no doubt a rudimentary self-consciousness when he talks about himself as about another object: yet the use of the forms ‘I,’ ‘me,’ may be taken to mark the greater precision of the idea of ‘self’ as not merely a bodily object and nameable just like other sensible things, but as something distinct from and opposed to all objects of sense, as what we call the ‘subject’ or _ego_.
