@avatar6v7,
Science is used for many things, both practical and impractical, so that's a difficult question -- I mean my field, which is medicine, is an applied science much like engineering. But fundamentally science is a discipline that seeks to understand the physical world, its constituents, and its processes, by way of observation. Every hypothesis in science is testable through observation (including experimentation), and every conclusion has reference to data generated through observation. Logic applies only insofar as one must place observations in context with one another.
Quote:participation is an interaction with another or others, in order to acheive somthing.
You use the word "intentionalist" synonymously with teleology. And teleology is basically anathema to science. It's like saying "we have a heart so that we can circulate blood". That is a teleological and non-scientific statement. All we can say is that the heart circulates blood. Sure, it's necessary, but it's not like the evolution or the embryonic development of the heart ever had the goal of circulation in mind -- it just so happens that the absence of a functioning heart (and circulation) is incompatible with life, and therefore does not persist.
So if I say that "glaciers
participate in erosion", it's a mechanical statement -- there is no intentionality, no
a priori purpose or goal contained in that statement. Participation need not imply that "in order to achieve something", and it's not used in that context in science.
