ABSTRACT
Here is one way to look at physics: there are some invisible things which are parts of everything else and whose behavior determines the way everything else works. Physics is the search for an accurate description of those invisible things, and it proceeds by finding better and better explanations of the visible. Eventually, by way of microbiological accounts of the mental, and through causal accounts of the mechanisms of language, we shall be able to see the physicists’ accumulation of truths about the world as itself a transaction between these invisible things.
