“[Of a wedding:] And so, standing before the aforesaid officiator, the two swore that at every other time of their lives till death took them, they would assuredly believe, feel, and desire precisely as they had believed, felt, and desired during the few preceding weeks. What was as remarkable as the undertaking itself was the fact that nobody seemed at all surprised at what they swore.”

From Critique of Everyday Life: Volume 1 (1947/1991)
Context: The method of Marx and Engels consists precisely in a search for the link which exists between what men think, desire, say and believe for themselves and what they are, what they do. This link always exists. It can be explored in two directions. On the one hand, the historian or the man of action can proceed from ideas to men, from consciousness to being - i. e. towards practical, everyday reality - bringing the two into confrontation and thereby achieving archieving criticism of ideas by action and realities. That is the direction which Marx and Engels nearly always followed in everything they wrote; and it is the direction which critical and constructive method must follow initially if it is to take a demonstrable shape and achieve results.
But it is equally possible to follow this link in another direction, taking real life as the point of departure in an investigation of how the ideas which express it and the forms of consciousness which reflect it emerge. The link, or rather the network of links between the two poles will prove to be complex. It must be unravelled, the thread must be carefully followed. In this way we can arrive at a criticism of life by ideas which in a sense extends and completes the first procedure.

Revelations of Divine Love (c. 1393), Chapter 2
Context: For the Third, by the grace of God and teaching of Holy Church I conceived a mighty desire to receive three wounds in my life: that is to say, the wound of very contrition, the wound of kind compassion, and the wound of steadfast longing toward God. And all this last petition I asked without any condition.
These two desires aforesaid passed from my mind, but the third dwelled with me continually.

First and Last Notebooks (1970)

Variant transcription from "Death of a Genius" in Life Magazine: "Certainly there are things worth believing. I believe in the brotherhood of man and the uniqueness of the individual. But if you ask me to prove what I believe, I can't. You know them to be true but you could spend a whole lifetime without being able to prove them. The mind can proceed only so far upon what it knows and can prove. There comes a point where the mind takes a leap—call it intuition or what you will—and comes out upon a higher plane of knowledge, but can never prove how it got there. All great discoveries have involved such a leap."
Unsourced variant: "The intellect has little to do on the road to discovery. There comes a leap in consciousness, call it intuition or what you will, and the solution comes to you and you do not know how or why. All great discoveries are made in this way." The earliest published version of this variant appears to be The Human Side of Scientists by Ralph Edward Oesper (1975), p. 58 http://books.google.com/books?id=-J0cAQAAIAAJ&q=%22solution+comes+to+you+and+you+do+not+know%22&dq=%22solution+comes+to+you+and+you+do+not+know%22&hl=en, but no source is provided, and the similarity to the "Life Magazine" quote above suggests it's likely a misquote.
