Are you saying there is no cause for the behavior besides external ones? How is stating that there are internal states circular?
These posts are getting bulky, so if you do not mind, I'll start small. Please feel free to redirect me to another part if I overlook something. I hope this will actually address more than just the small part I quote here.
The reason this is circular is that you are asserting that there is a causal inner state, the only evidence for which is its alleged behavioral effect. We observe a person acting, and infer an arrogant nature (to use your example). As long as this is merely a description of the actions, there is no problem. But when we take the further step of saying that he acts this way
because of his arrogant nature, we are guilty of circular reasoning. (BTW, this is precisely the reason we went from speaking of "type A personality" to using the phrase "type A behavior pattern"--it is intended to be descriptive, not causal.) Note that there is exactly the same evidence (the arrogant behavior) to support the notion that the gods who control this person's behavior are making him behave arrogantly. It is just that this no longer fits our world view.
I do not deny what you call internal states--I do think it is much more practical (and, I think, accurate) to think of them as
caused rather than
causal. Rather than saying that your sadness (as an example) made you act in a particular way, I think it much more fruitful to say that particular environmental events (which we may investigate--note that this is an empirical question here, and the presence of these events can, in theory, be manipulated in order to establish causality rather than just assert it) caused both your actions and your feelings of sadness. We can (again, at least in theory) manipulate these environmental events--how is it that we could directly manipulate a feeling of sadness? It is quite impossible for us to experimentally manipulate your hubris (I love that word) in order to see whether it does indeed influence your behavior. The best we can do is to manipulate environmental variables which might cause your hubris, and see what effects occur. In which case, of course, Occam suggests that the whole "hubris" step is superfluous, at least causally.
I think I will cut this short here, and wait for your reaction before moving on to anything else. Please believe me, I am not merely arguing for the sake of arguing, and I greatly appreciate your helpful attitude in this discussion.
