I want to go touching.
The ability to write concepts down bears on the ability to think as little and as much as the ability to draw hands bears on the ability to touch. Certainly, there is an important relation between noting something down (committing black marks to a piece of paper) and noticing it. This noticing and noting is then related in a variety of ways to the use of the thing noticed.
Wittgenstein said that the uses of philosophical words like "language" and "experience" are as humble as those of "lamp" and "door". We can extend this: their uses are as humble as those of lamps and doors. These objects, too, have their "usage".
We must approach the grammar of concepts (in writing) as one might approach the grammar of hands (in drawing). That is, the usage of marks on bits of paper.
