words denoting (bodily) activities, such as writing, speaking, etc. makes us look for an activity, different from these but analogous to them, corresponding to the word “thinking”.

And now, as the sentences are somewhere, we look for a place for the thought. (It is as though we looked for the place of the king of which the rules of chess treat, as opposed to the places of the various bits of wood, etc., the kings of the various sets.) ‒ ‒ ‒ We say, “surely the thought is something; it is not nothing”; and all one can answer to this is, that the word “thought” has its use, which is of a totally different kind from the use of the word “sentence”.
