According to this excerpt from "Loneliness . . . an American Malady" by Carson McCullers, what paradox do people struggle with in life?

Consciousness of self is the first abstract problem that the human being solves. Indeed, it is this self-consciousness that removes us from lower animals. This primitive grasp of identity develops with constantly shifting emphasis through all our years. Perhaps maturity is simply the history of those mutations that reveal to the individual the relation between himself and the world in which he finds himself.

After the first establishment of identity there comes the imperative need to lose this new-found sense of separateness and to belong to something larger and more powerful than the weak, lonely self. The sense of moral isolation is intolerable to us.

A.
Self-consciousness arises at an early age, but people continue to develop personality in later years.
B.
Maturity can only be gained once people become more aware of their personal needs.
C.
Even though other animals are unaware of self, humans and other animals still struggle with social conformity.
D.
Gaining awareness of one’s “self” causes a person to yearn for companionship with others.
