Friedrich Nietzsche said this quote

Truly, you understand the reverse art of alchemy, the depreciating of the most valuable things! Try, just for once, another recipe, in order not to realise as hitherto the opposite of what you mean to attain: deny those good things, withdraw from them the applause of the populace and discourage the spread of them, make them once more the concealed chastities of solitary souls, and say: morality is something forbidden! Perhaps you will thus attract to your cause the sort of men who are only of any account, I mean the heroic. But then there must be something formidable in it, and not as hitherto something disgusting!
