@Kielicious,
I just got done reading Block's argument that Kim's causal exclusion argument would result in "causal drainage," that was hot. Good stuff! However, as far as I understand it this is only a problem for Kim's argument if matter is made up of an infinite number of smaller and smaller "layers" each with different properties? Also, I don't consider it a problem at all for reasons I'll try to explain!
I'm definitely feeling a little limited by my lack of a higher education, but hey I'll give this a shot anyway.
Both Kim and Block seem to agree that this "Causal Drainage" occurs, they just disagree on where it stops. Where I start to have a problem is when I consider
just what is it that is supposedly draining away here? Neither of them seem to be making the case that this disctinction has any bearing on how objects interact, or how we should predict their interactions. Nor does this distinction seem to bear any relevance to the objects themselves. So, if causal drainage doesn't change any of the attributes of an object considered in and of itself, and doesn't change the manner in which we expect this object to interact with other objects, there is only one thing left that can be affected, and that is
our conception of the interactions of these objects.
Hume's arguments regarding causation: paraphrased by me!
To make this a little more interesting I'm going to proceed in a manner somewhat opposite to how Hume lays it out. First I'll start with the consideration that our perceptions and the objects they represent really are seperate. Actually I'm very sure you're familiar with this concept! I'll try to quickly move to the part that is important to the present subject.
We recognize that our perceptions are dependent on our senses, and appear to us in an interrupted manner, yet we observe a constancy in the manner in which our perceptions appear to us, so it is to reconcile the contradiction between the constancy in our perceptions and the inconstancy of our senses that we presume the existence of external objects. However, even though we make this distiction we still have no manner of forming an idea of these external objects but to conceive of them as the very same perceptions which we presume only to represent them.
In Hume's words "...it is impossible our idea of a perception, and that of an object or external existence can ever represent what are spefically different from each other." The consequence of this is that
the connections we observe between our perceptions or impressions cannot be safely assumed to apply to the objects they represent. The connection between a cause and it's effect, that
necessity or
power which we presume the cause to possess, is a connection that we observe between our impressions, which we cannot attribute to any specific attributes of the objects which we reason concerning. Nor does this idea of necessity arise from a view of the cause and its effect considered together. It is only the compulsion we feel to pass from the consideration of a cause to the consideration of it's effect which can account for this idea that a cause
must produce its effect.
I also tried to explain/paraphrase this in the Hume forum but I'm not sure how successful I was in either case.
So then, the only way to describe a causal relationship between external objects, without appealing to internal connections which we can't safely presume to have any external counterpart, is to say that when two [objects] are observed to be constantly conjoined in time and space, with one precedent to the other, that the one is the cause of the other. I put objects in brackets for emphasis, since the particular qualities of objects, being distinguishable by the mind, can be considered seperately and observed to be causes on their own, or to be the causally efficacious properties of an object if you prefer.

I hope this satisfies your curiosity about my earlier response to the Causal Drainage issue.
As a result of my being convinced by Hume's reasoning, I don't find Kim's causal exclusion very convincing, and even while I admire how concise Block's response to it was, I don't find causal drainage very alarming. What I do find convincing are experiments which carefully expose constant conjunctions between physical events and conscious experiences, and those which expose disjunctions between conscious will and actions.
