Nunca se debe gatear, cuando se tiene el impulso de volar (Never crawl when the impulse is to fly)

One can never ask anyone to change a feeling.

It is never permissible to say, I say.

Never can an authority admit that the intellectually courageous - those who dare to defy his authority - may be the most valuable type.

An existant can never justify the existence of another existant.

The self-surmounter can never put up with the man who has ceased to be dissatisfied with himself.

The physical capacity to coerce others can never generate a moral obligation to obey the dictates of [government] power.

The delusion of invincibility can never grow up in the mind of anyone except one who has never met a strong antagonist.

No one heals himself by wounding another.

No rebellious heart is ever at ease with paths established by others.

I don't give you permission to fail.

No man is justified in doing evil on the ground of expediency.

No man can demonstrate peace and cling to unhappiness.
