(Minor quibble: I’d be careful about using “should” here, as in “the heart should pump blood”, because “should” is often used in a moral sense. For instance, the COVID-19 spike protein presumably has some function involving sneaking into cells, it “should” do that in the teleological sense, but in the moral sense COVID-19 “should” just die out. I think that ambiguity makes a sentence like “but it might be another thing to say, that the heart should pump blood” sound deeper/more substantive than it is, in this context.
This puts me in mind of what I’ve been calling “the engineer’s ‘should’” vs “the strategist’s ‘should’” vs “the preacher’s ‘should’”. Teleological/mechanistic, systems-predictive, is-ought. Really, these ought to all be different words, but I don’t really have a good way to cleanly/concisely express the difference between the first two.
