Dr Luquet addresses himself to a very early period of life; as he said, to the pre-objectal undifferentiated period, which incidentally is also archaic, primitive, pre-verbal, as well as pre-objectal, and he refers to the problem of identity with subsequent capacity for the formation of object-relations. In addressing himself to this early construct he has courageously chosen to discuss one of the more confused issues in psycho-analytic theory—but it is an area which is probably most widely used in psycho-analytic communication.
