Realism Clew

 Realism Clew:

Very well.  There doesn't seem any way out of it.  If you want realism, thourough going realism, you have to hold to the immateriality of consciousness and the intellectual faculties.  This is the thread running through all of the various versions.  Plato has the forms or ideas impressed on the mind from their special realm.  The immateriality of the mind allows this pervasion and assures us that what we know and what is 'out there' is one and the same.  Philosophy tries to clear up the distortions that occur.  Aristotle and the Scholastics are more grounded, finding the relationship between the mind and the object the source of knowledge.  Aristotle says in Bk.XII of the metaphysics - "Everything which has not matter is indivisible".  This is I presume the core of the insight that object and mind can interpenetrate, that the object can be in the mind in its subtle form as it really is.  The mind grasps the reality of the object.  If we do not accept this as the default position then as Maritain writes:

"But it also indicates that there is an incomparable unity, a unity deeper than that between a model and a transfer, between the thing and thought, thought in act, I mean. For if things were modified or changed in any way by sensation or intellection (I do not mean in the conditions in which they exist, in their way of existing, I mean in regard to those things that properly constitute them, in what they are), then there would no longer be any truth or knowledge. Then the theorist of knowledge could not even express himself by wagging his finger because in such a case there would be left but two equally impossible recourses: either to say that knowledge implies a relation to things but deforms those things, and as a result they are never known; or else to say that knowledge implies no relation to things and that it is an absolute unfolding of thought having only itself as object. This is a position which is quite incompatible with the fact of error and negative ideas." ( from 'The Degrees of Knowledge")

Advaitins likewise relay on the immateriality of consciousness with the joint theory of vritti (mental modification) and upadhi (form of limitation/object) allowing knowledge to happen.  As in all the various schemas of Realism the fine print can be intricate.
