@Setanta,
Frank if Set doesn't want to respond then you can it's all about your 'new' questions:
Your post is 'woolly' why not be specific.
Pick a teaching that is said by Buddhists, to be a teaching by the Buddha, and refute it. For example the Buddha said that there is no self, ego, Atman, soul (all are synonymous for the purposes of this discussion). Please prove that there is a self. The burden of proof is with you because the Buddha is saying 'you say there is a self, show me where the self is located'.
Now if you can't do that then that removes the subject from subject/object dualism. So unless you can show there is a self then how are you going to show that dualism is correct? The self must either be in the body, mind, both or some other location. If not then you cannot assert a self or dualism because if you don't have self then you can't have other.
They (subject/object) are merely ‘dreamed up by the mind’ concepts we use to communicate; that’s fine but the self is just a useful fiction, as is dualism. If you can’t find a truly existing self then the other side of the coin 'other' is also not found because the concepts depend on one another.
Buddha isn’t saying there is something else, he's just saying dualism is a fiction based on the mistaken belief there is a truly existent self. When we look for it the self cannot be found. The absence of dualism, the mere negation of it or the letting go of it is the absolute is ultimate reality. So it’s not something it’s the absence of mistaken views based on the subject/object dualism that cannot be proved.
The burden of proof is with anyone who says there is a truly existing self. The Buddha just says OK find it and I'll believe in it; if not then I won’t believe in dualism.
Abosolute truth is the mere absence of the belief in dualism.
