“The American who first discovered Columbus made a bad discovery.”

The Idiot (1868–9)
Context: It wasn't the New World that mattered … Columbus died almost without seeing it; and not really knowing what he had discovered. It's life that matters, nothing but life — the process of discovering, the everlasting and perpetual process, not the discovery itself, at all. But what's the use of talking! I suspect that all I'm saying now is so like the usual commonplaces that I shall certainly be taken for a lower-form schoolboy sending in his essay on "sunrise", or they'll say perhaps that I had something to say, but that I did not know how to "explain" it. 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. But if I too have failed to convey all that has been tormenting me for the last six months, it will, anyway, be understood that I have paid very dearly for attaining my present "last conviction." This is what I felt necessary, for certain objects of my own, to put forward in my "Explanation". However, I will continue.

Context: We learn wisdom from failure much more than from success. We often discover what will do, by finding out what will not do; and probably he who never made a mistake never made a discovery.

The Discovery of India (1946)
Context: The discovery of India — what have I discovered? It was presumptuous of me to imagine that I could unveil her and find out what she is today and what she was in the long past. Today she is four hundred million separate individual men and women, each differing from the other, each living in a private universe of thought and feeling. If this is so in the present, how much more so to grasp that multitudinous past of innumerable successions of human beings. Yet something has bound them together and binds them still. India is a geographical and economic entity, a cultural unity amidst diversity, a bundle of contradictions held together by strong but invisible threads. Overwhelmed again and again her spirit was never conquered, and today when she appears to be a plaything of a proud conqueror, she remains unsubdued and unconquered. About her there is the elusive quality of a legend of long ago; some enchantment seems to have held her mind. She is a myth and an idea, a dream and a vision, and yet very real and present and pervasive.

Critique of the Hegelian Dialectic and Philosophy as a Whole, p. 64.
Paris Manuscripts (1844)
Context: Feuerbach is the only one who has a serious, critical attitude to the Hegelian dialectic and who has made genuine discoveries in this field. He is in fact the true conqueror of the old philosophy. The extent of his achievement, and the unpretentious simplicity with which he, Feuerbach, gives it to the world, stand in striking contrast to the opposite attitude (of the others). Feuerbach’s great achievement is: (1) The proof that philosophy is nothing else but religion rendered into thought and expounded by thought, i. e., another form and manner of existence of the estrangement of the essence of man; hence equally to be condemned;(2) The establishment of true materialism and of real science, by making the social relationship of “man to man” the basic principle of the theory; (3) His opposing of the negation of the negation, which claims to be the absolute positive, the self-supporting positive, positively based on itself.
