From The Study...a conversation on possibilities

What are the stimuli which arouse the impulse to escape in human beings?
The word which first presents itself in answer to the question is danger.
Fear is aroused by danger. This in turn leads to the question...danger to what?
The concept becomes enlarged if we say that a man will become
afraid if he detects danger physically, emotionally, and especially beliefs.
The concept can be enlarged still further if again the biological purpose
of fear is to ensure survival.

This makes sense particularly if survival is thought of not merely in terms of physical
existence, but survival of the ego, survival of personality, survival as somebody rather than
NOBODY?
