Descartes' 'Ghost in the Machine' : To What Extent is it a 'Category Mistake' (Gilbert Ryle)?
At the moment, I am finding the ideas of Ryle very helpful, and I am happy to share with you and anyone else who is interested. I nearly put the ideas onto the one on the poll on materialism, idealism and realism, but as it such a popular one, even though it started as a poll, I decided that the ideas of Ryle would probably get lost there entirely. My own reading of Ryle is that it raises the question of what is 'mind' in a fundamental way and the conception of consciousness itself.
Ryle traces the emergence of the idea of consciousness. He says,
'When the epistemologists' concept of consciousness first became popular, it seems to have been in part a transformed application of the Protestant notion of conscience...When Galileo and Descartes' representations of the mechanical world seemed to require that minds should be solved from mechanism by being represented as constituting a duplicate world, the need was felt to explain how the ghostly world could be ascertained, again without sensory perception.'
Ryle goes on to speak of how Locke understood inner states, and called this,
'supposed inner perception "reflection"(our introspection), borrowing the word "reflection" from the the familiar optical phenomenon of the reflections of faces in mirrors. The mind can "see" or look at it's own operations in the light given by themselves. The myth of consciousness is a piece of para-optics'.
In this way, Ryle is calling into question the idea of consciousness itself, especially in relation to what inner experience means and its significance in understanding the nature of 'reality', with the division of inner and outer being an important interface. He is questioning the nature of knowledge and how it connects to self-knowledge, which is such a crucial link in the interplay between subjective and objective understanding.
