Survival Instinct
So the instinct for survival, which translates into fear of annihilation
and death, is the energy behind adaptation and hence, conditioning.
The child finds himself in the situation of having to be what
his environment (parents) dictates in order for him to survive.
So we can say that it is due to the instinct for self-preservation
that acquiescence to the coercive forces in the environment occurs.
The child, then, adopts his parents' values and attitudes or rebels
against them. In either case, he is conditioned to be and to act
in certain ways, which, through the passage of time, become so
ingrained that he takes them to be his identity. Slowly he forgets
his true identity and becomes what he is being conditioned to
be and to believe. (Work on the Superego, pg 2)
