“Within the extent of your knowledge, you are right.”

“Live and act within the limit of your knowledge and keep expanding it to the limit of your life.”

“In the name of the best within you, do not sacrifice this world to those who are at its worst. In the name of the values that keep you alive, do not let your vision of people be distorted by the ugly, the cowardly, the mindless in those who have never achieved integrity. Do not lose your knowledge that our proper estate is an upright posture,an intransigent mind and a step that travels unlimited roads. Do not let your fire go out, spark by irreplaceable spark, in the hopeless swamps of the approximate, the not-quite, the not-yet, the not-at-all. Do not let the hero in your soul perish, in lonely frustration for the life you deserved, but have never been able to reach. Check your road and the nature of your battle. The world you desired can be won, it exists, it is real, it's yours.”

“Learn to distinguish the difference between errors of knowledge and breaches of morality. An error of knowledge is not a moral flaw, provided you are willing to correct it; only a mystic would judge human beings by the standard of an impossible, automatic omniscience. But a breach of morality is the conscious choice of an action you know to be evil, or a willful evasion of knowledge, a suspension of sight and of thought. That which you do not know, is not a moral charge against you; but that which you refuse to know, is an account of infamy growing in your soul. Make every allowance for errors of knowledge; do not forgive or accept any break of morality.”

“Man has no automatic code of survival. His particular distinction from all other living species is the necessity to act in the face of alternatives by means of volitional choice. He has no automatic knowledge of what is good for him or evil, what values his life depends on, what course of action it requires. Are you prattling about an instinct of self-preservation? An instinct of self-preservation is precisely what man does not possess. An 'instinct' in as unerring and automatic form of knowledge. A desire is not an instinct. A desire to live does not give you the knowledge required for living. And even man's desire to live is not automatic: your secret evil today is that that is the desire you do not hold. Your fear of death is not a love of life and will not give you the knowledge needed to keep it. Man must obtain his knowledge and choose his actions by a process of thinking, which nature will not force him to perform. Man has the power to act as his own destroyer--and that is the way he has acted through most of history.”

“You'll come back, because yours is an error of knowledge, not a moral failure, not an act of surrender to evil, but only the last act of being victim to your own virtue. We'll wait for you and when you come back, you will have discovered that there need never be any conflict among your desires, nor so tragic a clash of values as the one you've borne so well.”

“Do not lose your knowledge that man's proper estate is an upright posture, an intransigent mind, and a step that travels unlimited roads”
