A heresy can spring only from a system that is in full vigor.

Absolute faith corrupts as absolutely as absolute power.

It is thus with most of us; we are what other people say we are. We know ourselves chiefly by hearsay.

It is also plausible that those movements with the greatest inner contradiction and between profession and practice - that is to say with a strong feeling of guilt - are likely to be the most fervent in imposing their faith on others.

Action can give us the feeling of being useful, but only words can give us a sense of weight and purpose.

The remarkable thing is that we really love our neighbor as ourselves: we do unto others as we do unto ourselves. We hate others when we hate ourselves. We are tolerant toward others when we tolerate ourselves. We forgive others when we forgive ourselves. We are prone to sacrifice others when we are ready to sacrifice ourselves.

Every extreme attitude is a fight from the self.
