ABSTRACT
THE COMMON THEME OF THE FOLLOWING STUDIES CONCERNS THE great metamorphosis of man from embryonic life within the maternal womb to existence in the human and natural world. Only certain functions of the human mind are considered here: emotion, perception, focal attention, and memory; but the attempt is made to understand some aspects of their development in the light of the over-all significance of the change from foetal to adult state. The point of departure, in time, of these studies is that of the newborn infant, and while none of them pursues every step of childhood development, they all consider the implications of some of the major changes for the life of the adult.
