Hi Daniel,
Thank you for expanding a little on your project. Since I'm also working on the mind - body problem, it's always interesting to hear how other approach the issue. As of yet, I cannot say I understand the basic merit of your position. I have difficulties with your interpretation of Russell, I have difficulties with your use of ontological categories and finally some questions about your own position.
It is a substance dualism that explains how
physical and phenomenal properties can both be parts of the same physical
world. It holds that the physical universe is not completely described by
contemporary or Classical physics and that physicalism is false.
If the world you claim to be the real one is
wholly physical, how can it contain non-physical substances? And if it does
not, how can your position rightly be called 'substance dualism'? The view that
the physical universe is not completely described by contemporary physics is
uncontroversial. It certainly does not follow from that that physicalism is
false.
I have some problems with your interpretation of
Russell:
This treatment leaves open the question of
whether dispositions also have a categorical basis.
I don't think Russell leaves it open whether
dispositions have a categorical basis (I don't believe Russell uses the term
'categorical basis'). It is necessary that they do: we describe events by
abstracting from sense experience the structural properties of their cause. A
'property' is identified by how it designates that cause. For an event,
anything, to exist, it must be a certain way and in this sense too, it will
have properties. It is due to these intrinsic properties that something interacts
with other things.
Russell sees no reason why intrinsic
qualities must have a physical basis, but they could.
I do not recognize Russell in this statement
(although it may be a Russellian position). Russell talks of physical and
mental knowledge; not so much of physical and mental things or properties. If
he talks of any basis at all, it is the 'neutral basis' of sense perception.
The same data, namely perceptions, can be used to arrive at physical knowledge
of an outside stimulus or psychological knowledge of the one having the
perceptions. If we want to reserve the term physical for properties or
substances or events, I suggest that something is physical when it is the
referent of physical knowledge. Mental descriptions describe the same referent
as does a physical description of a brain process. So Russell sees every reason
to believe intrinsic qualities must also be physical, but no reason to call the
physical the basis of the mental. The mental is what it is; it has no 'basis'
(it has causes, like the outside stimuli, and various non-conscious parts of
the brain).
But if dispositions also must have a categorical
basis, it is not at all clear how they could be of the same categorical
basis.
I take it this is you responding to Russell? I
don't understand what you're saying here: how could dispositional properties be
of the same categorical basis as what?
Mental properties are intrinsic, categorical by definition, they have no
further categorical basis.
Thus RM has this fundamental tension at its
core. It would have to be a monist ontology that supports property dualism.
Well,
there's certainly something to be worked out here. But I certainly think we
would not want it to be that Russellian Monism has to be a monist ontology that
supports property dualism. The reason is this: if property dualism is supposed
to be ontological dualism, then we have a dualist ontology right here and what
you are proposing makes no sense. If you do not think property dualism is an
ontological dualism, then what kind of dualism do you think it is? I suggest we
take dualism and monism always to be
ontological positions, just for the sake of much needed clarity.
So the one "event" has to account for
both dispositional properties which have "manifestations" and
categorical properties which do not, despite our undeniable acquaintance with
them
Well, this
is a difficult issue, but dispositional properties would have the event as
their relevant cause, which in turn has an intrinsic nature; properties that account
for dispositional properties.
A "disposition-only" ontology like
that of John Heil and C.B.Martin,
tries to identify qualities with dispositions, seeing
qualities as another aspect of the same dispositional property. But this still
begs the question of how a single property can have 2 such radically different
"aspects".
I'm looking forward to reading Heil, but haven't
as of yet. From what I can tell, what Heil and Martin are saying is another way
of making Russell's point. For Russell, no question is begged: one is an
abstraction from the effected sense experience, ascribed to a cause. The other
is lived experience. The radical epistemic difference accounts for the
radically different aspects.
As for your own approach, there are three things
that are unclear to me: 1. Is the intrinsic property of animals phenomenal? And
only phenomenal? Does 'phenomenality' render the intrinsic property
non-physical? 2. What is the benefit of considering substances rather than
events or any other ontological class? Assuming that you do not deny that there
are events, would you not have to give some account of what is going on there?
3. Why do you insist on epiphenomenalism, when you could have done without it
by adopting a Russellian (or any old Identity Theory) view?
