Sensory Experience, Rational Knowledge and Contemplation: Are There Category Errors of Knowledge?
I don't think that Wilber was trying to depict a new paradigm and recognised that some philosophy in the past had a more synthetic approach. He may have not been that influencd by Spinoza because I have just looked in the index and there is no entry in the volume which I am reading.
My understanding of what Wilber means by contemplation is both of speculative reflection and experience of a mystical nature. He draws upon the ideas of the Christian mystic, St Bonadventure but incorporates the general stance of meditation, suggesting that meditation is 'a sustained instrumental path of transcendence'. He also incorporates the idea of the 'perennial philosophy, stating,
'The most striking feature of the perennial philosophy/psychology is that it presents being and consciousness as a nested harvest of dimensional levels, moving from densest , and most fragmentary realms to the highest, subtlest and most unitary ones'
His understanding of the absolute is the paradox underlying all experiences, stating that 'the Absolute is both the highest state of being and the ground of all being; it is both the goal of evolution the ground of evolution; the stage of development and the reality or suchness of all .development; the highest of all conditions and the highest of all conditions and the Condiion of all conditions; the highest rung in the ladder and the wood out of which the entire ladder is made...'
I have to admit that I am not completely convinced of his line of argument in many places because he seems to be talking in riddles. However, I do think that he is into something, especially as he draws upon hermeurics as the way of human meaning which cannot be captured fully through empirical proof or the analysis of rationality.
