“Meekness-induced prejudices have no place in the society of thinking humanity.”

“We have now sunk to a depth at which restatement of the obvious is the first duty of intelligent men.”

“Now that science has helped us to overcome the awe of the unknown in nature, we are the slaves of social pressures of our own making. When called upon to act independently, we cry for patterns, systems, and authorities. If by enlightenment and intellectual progress we mean the freeing of man from superstitious belief in evil forces, in demons and fairies, in blind fate–in short, the emancipation from fear–then denunciation of what is currently called reason is the greatest service reason can render.”

“The zipper displaces the button and a man lacks just that much time to think while dressing at dawn, a philosophical hour, and thus a melancholy hour.”

“Conformity to the present is invisibility to the future.”

“…[G]reat progress was evident in the last Congress of the American ‘Labour Union’ in that among other things, it treated working women with complete equality. While in this respect the English, and still more the gallant French, are burdened with a spirit of narrow-mindedness. Anybody who knows anything of history knows that great social changes are impossible without the feminine ferment. Social progress can be measured exactly by the social position of the fair sex (the ugly ones included).”

“Philosophy hasn’t made any progress? – If somebody scratches the spot where he has an itch, do we have to see some progress? Isn’t genuine scratching otherwise, or genuine itching itching? And can’t this reaction to an irritation continue in the same way for a long time before a cure for the itching is discovered?”

“An age cannot bind itself and ordain to put the succeeding one into such a condition that it cannot extend its (at best very occasional) knowledge , purify itself of errors, and progress in general enlightenment. That would be a crime against human nature, the proper destination of which lies precisely in this progress and the descendants would be fully justified in rejecting those decrees as having been made in an unwarranted and malicious manner.The touchstone of everything that can be concluded as a law for a people lies in the question whether the people could have imposed such a law on itself.”

“Without deviation from the norm, progress is not possible.”

“We can only see a short distance ahead, but we can see plenty there that needs to be done.”

“No, our science is no illusion. But an illusion it would be to suppose that what science cannot give us we can get elsewhere.”

“The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.”
