when you say thought do you mean conscious reflection or just the chemical activities in the brain that correspond to some action? of course i do not suggest that conscious reflection consists of anything beyond chemical activities in the brain (i.e., this is not a metaphysical question), but that they are different kinds of actions, probably. in day to day use of the language, i will propose, the former (conscious reflection) is what is meant by thought. if you agree, then do you still hold that thought precedes motion? that a baby emerging from the womb thinks out its actions, in this conscious sense, before it kicks its limbs and utters its first scream? please note that i am not being facetious here, but only trying to nail down some of these terms in a sense that i (and other lay people perhaps) might understand. though i am not going to attempt it here, i think similar questions can be raised regarding ritual, and to be a bit bolder, even about academic learning, where one repeats processes over and over before a conscious understanding and the capability to think about the matter emerges.
i hope that you will not lable me too a fool for raising these questions, though i will admit they are tentative and might not hence meet your requirements of rigour or clarity!
