(My Master's thesis in Philosophy (never finished) was to be about another hotly debated topic..the "Free Will" vs "Determinism" issue.)

DO we have free will? Or are our actions simply based on physics & chemistry? My claim was to be: that the only way of even approaching a substantive resolution was through some theory like A.N. Whitehead's, where each 'actual entity' had a certain latitude about what it could 'do'...which would allow the organism to actually 'make decisions'...in some circumstances.
So, I was essentially arguing that we can't know, ultimately, what the answer is...but we must continue to act as though we DO have free will, no matter what 'truth' is.
