The Human Question

By using qualitative change, one avoids objections about momentum. Also worth considering: how qualitative change is correlated with quantifiable changes (e.g. increase in heat is identified with acceleration). Also worth considering is the question of whether there is ever a purely quantitative change (i.e., one with no concomitant qualitative change). Also worth considering is whether qualitative change can be ultimately explained by constants, i.e., laws of nature, and how such laws relate to what Aquinas meant when he said that the accidental is reducibe to the essential.  The combination of laws of nature and incidental facts regarding quantity and quality would predict--but would it explain? Also worth considering is whether an affirmation of the previous question is anti-humanistic (it is). Finally, qualitative change in a human being (e.g., learning, discovering, trying, etc.) how are answers to the previous questions about causality that related to agency? (this ...

Infinite regress arguments are all over the place, not just in old fashioned places, like Aquinas's first way. In fact, Galileo's proposal that an already-rolling marble rolling down an infinitely long flat and frictionless plane would continue to do so infinitely... is an infinite regress. But it is by thinking of such infinite regresses that we come up with many novel concepts, insights.
