What is left over if I subtract the fact that my arms goes up from the fact that I raise my arm?

The philosophical I is not the human being, not the human body or the human soul with the psychological properties, but the metaphysical subject, the boundary (not a part) of the world.

A picture held us captive. And we could not get outside it, for it lay in our language and language seemed to repeat it to us inexorably.

I might say: if the place I want to get to could only be reached by way of a ladder, I would give up trying to get there. For the place I really have to get to is a place I must already be at now. Anything that I might reach by climbing a ladder does not interest me.

An inner process stands in need of outward criteria.

How small a thought it takes to fill a life.

When philosophers use a word--"knowledge," "being," "object," "I," "proposition," "name"--and try to grasp the essence of the thing, one must always ask oneself: is the word ever actually used in this way in the language-game which is its original home?--What we do is to bring words back from their metaphysical to their everyday use.
