insecurity

Only the insecure strive for security.

It is when we all play safe that we create a world of utmost insecurity.

If men as individuals surrender to the call of their elementary instincts, avoiding pain and seeking satisfaction only for their own selves, the result for them all taken together must be a state of insecurity, of fear, and of promiscuous misery.

It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature.
