You may conclude that as a result of the deeper study of the dream-work we gain valuable information about the rather unknown beginnings of our intellectual development. I trust this will be true, but this work has not, up to the present time, been undertaken. The antiquity into which the dream-work carries us back is of a double aspect, firstly, the individual antiquity, childhood; and, secondly (in so far as every individual in his childhood lives over again in some more or less abbreviated manner the entire development of the human race), also this antiquity, the philogenetic. That we shall be able to differentiate which part of the latent psychic proceeding has its source in the individual, and which part in the philogenetic antiquity is not improbable. In this connection it appears to me, for example, that the symbolic relations which the individual has never learned are ground for the belief that they should be regarded as a philogenetic inheritance. However, this is not the only archaic characteristic of the dream. You probably all know from your own experiences the peculiar amnesia, that is, loss of memory, concerning childhood. I mean the fact that the first years, to the fifth, sixth or eighth, have not left the same traces in our memory as have later experiences. One meets with individual persons, to be sure, who can boast of a continuous memory from the very beginning to the present day, but the other condition, that of a gap in the memory, is far more frequent. I believe we have not laid enough stress on this fact. The child is able to speak well at the age of two, it soon shows that it can become adjusted to the most complicated psychic situations, and makes remarks which years later are retold to it, but which it has itself entirely forgotten. Besides, the memory in the early years is more facile, because it is less burdened than in later years. Nor is there any reason for considering the memory-function as a particularly high or difficult psychic performance; in fact, the contrary is true, and you can find a good memory in persons who stand very low intellectually.
