Learn from the mistakes of others. You can't live long enough to make them all yourself. Boredom sets into boring minds. The more original a discovery, the more obvious it seems afterwards.

Some of the greatest discoveries...consist mainly in the clearing away of psychological roadblocks which obstruct the approach to reality; which is why,post factum they appear so obvious.

...the crimes of violence committed for selfish, personal motives are historically insignificant compared to those committed ad majorem gloriam Dei, out of a self-sacrificing devotion to the flag, a leader, a religeous faith or political conviction.

The principle mark of genius is not perfection but originality, the opening of new frontiers.

The greatest temptation for the like of us is: to renounce violence, to repent, to make peace with oneself. Most revolutionaries fell before this temptation, from Spartacus to Danton and Dostoevsky; they are the classical form of betrayal of the cause. The temptations of God were always more dangerous for mankind than those of Satan. As long as chaos dominates the world, God is an anachronism; and every compromise with one’s own conscience is perfidy. When the accursed inner voice speaks to you, hold your hands over your ears….

I profoundly admire Aldous Huxley, both for his philosophy and uncompromising sincerity. But I disagree with his advocacy of 'the chemical opening of doors into the Other World', and with his belief that drugs can procure 'what Catholic theologians call a gratuitous grace'. Chemically induced hallucinations, delusions and raptures may be frightening or wonderfully gratifying; in either case they are in the nature of confidence tricks played on one's own nervous system.

The moment of truth, the sudden emergence of a new insight, is an act of intuition.
