The fact that man’s birth is primarily a negative act, that of being thrown out of the original oneness with nature, that he cannot return to where he came from, implies that the process of birth is by no means an easy one. Each step into his new human existence is frightening. It always means to give up a secure state, which was relatively known, for one which is new, which one has not yet mastered. Undoubtedly, if the infant could think at the moment of the severance of the umbilical cord, he would experience the fear of dying. A loving fate protects us from this first panic. But at any new step, at any new stage of our birth, we are afraid again. We are never free from two conflicting tendencies: one to emerge from the womb, from the animal form of existence into a more human existence, from bondage to freedom; another, to return to the womb, to nature, to certainty and security. In the history of the individual, and of the race, the progressive tendency has proven to be stronger, yet the phenomenon of mental illness and the regression of the human race to positions apparently relinquished generations ago, show the intense struggle which accompanies each new act of birth
