"But I’ll add though 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 ideas for thirty-five years; there’s something left which cannot be induced to emerge from your brain, and remains with you for ever, and with it you will die, without communicating to anyone perhaps, the most important of your ideas."
— Fyodor Dostoyevsky, The Idiot

Natasya was overcome with a fit of laughter.
