Re: The Arrow of Time in Cat (David Corfield)

Here's a couple of other things to think about:
__One__
Discussions of the 2-place relation "x determines y"
are frequently confounded by several different senses
of the word "determine".
There are at least these two senses:
1. Formal, informational, or mathematical determination:
* "two points determine a line"
2. Material, causal, or physical determination:
* "push determines shove"
What exactly do we mean by "the" cause and "the" effect, anyway?
Do we mean a totality of events that we call "the cause" of a given effect?
Do we mean a totality of events that we call "the effect" of a given cause?
__Two__
In the propositions as types analogy, we have a suggestive relation
between the function arrow "->$" and the implication arrow "=>".
But if we say that function arrows are arrows of time, do we really want to
say that implication arrows are arrows of time, and in the same sense, too?
