“Ages of prolonged uncertainty, while they are compatible with the highest degree of saintliness in a few, are inimical to the prosaic every-day virtues of respectable citizens. There seems no use in thrift, when tomorrow all your savings may be dissipated; no advantage in honesty, when the man towards whom you practise it is pretty sure to swindle you; no point in steadfast adherence to the cause, when no cause is important or has a chance of stable victory; no argument in favour of truthfulness, when only supple tergiversation makes the preservation of life and fortune possible. The man whose virtue has no source except a purely terrestrial prudence will in such a world, become an adventurer if he has the courage, and, if not, will seek obscurity as a timid time-server.”

“Courage is reckoned the greatest of all virtues; because, unless a man has that virtue, he has no security for preserving any other.”

“There is no soul; there is only consciousness, the highest thing man ever has! Losing the conscious means to die! Death is not a door; when our conscious is gone, all is gone! Only the existence has the doors! Only the life presents you doors! You can save yourself only when you are alive, not after because there is no after! The first step for salvation is to know this simple truth!”

“The real advantage which truth has, consists in this, that when an opinion is true, it may be extinguished once, twice or many times, but in the course of ages there will generally found person to rediscover it, until some of its reappearances falls on a time when from favourable circumstances it escapes persecution until it has made such head as to withstand all subsequent attempts to suppress it.”

“A strict observance of the written laws is doubtless one of the highest virtues of a good citizen, but it is not the highest. The laws of necessity, of self-preservation, of saving our country when in danger, are of higher obligation. To lose our country by a scrupulous adherence to written law would be to lose the law itself, with life, liberty, property and all those who are enjoying them with us; thus absurdly sacrificing the end to the means.”

“When one has nothing to lose, one becomes courageous. We are timid only when there is something we can still cling to.”
