A philosopher always finds more grass to feed upon in the valleys of stupidity than on the arid heights of intelligence.

Here the term 'language-game' is meant to bring into prominence the fact that the speaking of language is part of an activity, of a form of life.

Just be indipendent of the external world, so you don't have to fear for what's in it.

Man feels the urge to run up against the limits of language. Think for example of the astonishment that anything at all exists. This astonishment cannot be expressed in the form of a question, and there is also no answer whatsoever. Anything we might say is a priori bound to be nonsense. Nevertheless we do run up against the limits of language. Kierkegaard too saw that there is this running up against something, and he referred to it in a fairly similar way (as running up against paradox). This running up against the limits of language is ethics.

Philosophy is like trying to open a safe with a combination lock: each little adjustment of the dials seems to achieve nothing, only when everything is in place does the door open.

Tell them I've had a wonderful life.

We learn by rearranging what we know.
