[11, 12] Words as tools, parts of machines each part having a context / use. The relationships between parts might constitute a grammar. R. Crumb's Mr. Natural was famous (in my day) for exhorting, "Get the right tool for the job!" Context is everything. Okay, we employ tools in a certain order to achieve certain ends, but is this mere instrumentalism? I have the sense that what Wittgenstein is after is more interesting. If we must get the right tool for the job, how do we go about knowing which is the right one? (Presumable, we know what the job is.) Selecting the right tool in context must have to do with a kind of moral accuracy.
