“In every idea emanating from genius, or even in every serious human idea -- born in the human brain -- there always remains something -- some sediment -- which cannot be expressed to others, though one wrote volumes and lectured upon it for five-and-thirty years. There is always a something, a remnant, which will never come out from your brain, but will remain there with you, and you alone, for ever and ever, and you will die, perhaps, without having imparted what may be the very essence of your idea to a single living soul.”

“Let me add to this that in every idea emanating from genius, or even in every serious human idea—born in the human brain—there always remains something—some sediment—which cannot be expressed to others, though one wrote volumes and lectured upon it for five-and-thirty years. There is always a something, a remnant, which will never come out from your brain, but will remain there with you, and you alone, for ever and ever, and you will die, perhaps, without having imparted what may be the very essence of your idea to a single living soul.”

“Let me add, however, that in every idea of genius or in every new human idea, or, more simply still, in every serious human idea born in anyone's brain, there is something that cannot possibly be conveyed to others, though you wrote volumes about it and spent thirty-five years in explaining your idea; something will always be left that will obstinately refuse to emerge from your head and that will remain with you for ever and you will die without having conveyed to anyone what is perhaps the most vital point of your idea.”

“There is something at the bottom of every new human thought, every thought of genius, or even every earnest thought that springs up in any brain, which can never be communicated to others, even if one were to write volumes about it and were explaining one's idea for thirty-five years; there's something left which cannot be induced to emerge from your brain, and remains with you forever; and with it you will die, without communicating to anyone perhaps the most important of your ideas.”

“But I'll add, that there is something at the bottom of every new human thought, every thought of genius, or even every earnest thought that springs up in any brain, which can never be communicated to others, even if one were to write volumes about it and were explaining one's idea for thirty-five years; there's something left which cannot be induced to emerge from your brain, and remains with you forever; and with it you will die, without communicating to anyone perhaps the most important of your ideas”
