Still crunching through this, but it made me think in some interesting ways.
I'd be interested to see how his perspective changes after being introduced to Lamba Calculus. Everything can be represented with functions. Everything.
Which says something about the nature of many things: sets, relations, computability. Verbs, actions.
If everything is (or can be) a function (a transformation, a verb, an action), does that imply anything about philosophy or reality? Does that give us something resembling Mahayana Buddhism, or lend credence to it?
What if we view energy as a function and matter as a state? Mass–energy equivalence tells us energy can be converted to matter. Then, what if we view matter as a function which returns a state? For example, the C function
int fortytwo() {return 42;}
acts as a state, to anyone calling it. But it is most definitely a function. What if matter is the same way: a function (energy) which has been configured to appear as state?
