Harry Potter and the Deathly Hallows by J. K. Rowling

And shortly afterward he had set to work, alone, digging the grave in the place that Bill had shown him at the end of the garden, between bushes. He dug with a kind of fury, relishing the manual work, glorying in the non-magic of it, for every drop of his sweat and every blister felt like a gift to the elf who had saved their lives.

Wittgenstein’s Lectures on the Foundations of Mathematics Edited by Cora Diamond

Wittgenstein’s Lectures on the Foundations of Mathematics, Cambridge, 1939, Edited by Cora Diamond

Wittgenstein: What a mathematician gives you is a model which can then be used for certain purposes.

What is the relationship between trying to solve it and solving it? How would it be intelligible to say, “He looked for it and then found it”? Isn’t it absurd to say that?

Turing: Is it not at all absurd. It is like “He looked for a white lion” or “a white animal between a lion and a horse”.

Wittgenstein: But it is not like that. The very point of this discussion is to see the great difference…Have you found a white animal if you’ve drawn it? Could I draw the construction of the heptagon before I find it?

Turing: One could explain how to recognize the construction of the heptagon.

Wittgenstein: Yes, but that is very different from the description of a white lion. In the case of the white lion you can say what it will be like when you’ve found it. But not so in the case of the heptagon…The result of one’s search for the construction is that one finds that the question is meaningless.

Isn’t it queer–you look for something by drawing things. What the hell? You’re not looking for something.
