“If we reason that we want happiness for others, not for ourselves, then we ought justly to be suspected of failing to recognize human nature for what it is and of wishing to turn men into machines.”

“To judge a man means nothing other than to ask: What content does he give to the form of humanity? What concept should we have of humanity if he were its only representative?”

“I am more and more convinced that our happiness or unhappiness depends far more on the way we meet the events of life, than on the nature of those events themselves.”

“The sum of the knowable, that soil which the human spirit must till, lies between all the languages and independent of them, at their center. But man cannot approach this purely objective realm other than through his own modes of cognition and feeling, in other words: subjectively. Just where study and research touch the highest and deepest point, just there does the mechanical, logical use of reason - whatever in us can most easily be separated from our uniqueness as individual human beings - find itself at the end of its rope. From here on we need a process of inner perception and creation. And all that we can plainly know about this is its result, namely, that objective truth always rises from the entire energy of subjective individuality.”

“For even if we know very little that is certain about spirit or soul, the true nature of the body, of materiality, is totally unknown and incomprehensible to us.”

“It is an absolutely vain endeavor to attempt to reconstruct or even comprehend the nature of a human being by simply knowing the forces which have acted upon him. However deeply we should like to penetrate, however close we seem to be drawing to truth, one unknown quantity eludes us: man's primordial energy, his original self, that personality which was given him with the gift of life itself. On it rests man's true freedom; it alone determines his real character.”

“Human nature must be something which always remains one and the same, but which may be carried out in manifold ways.”
