Conciousness....

CONSCIOUS experience is the most familiar thing in the world and the most mysterious.

There is nothing we know about more directly than consciousness, but it is extraordinarily hard to reconcile it with everything else we know. Why does it exist? What does it do? How could it possibly arise from neural processes in the brain?

From an objective viewpoint, the brain is relatively comprehensible. When you look at this blog, there is a whir of processing: photons strike your retina, electrical signals are passed up your optic nerve and between different areas of your brain, and eventually you might respond with a smile, a perplexed frown or a remark.

But there is also a subjective aspect. When you look at the page, you are conscious of it, directly experiencing the images and words as part of your private, mental life. You have vivid impressions of the colors and shapes of the images. At the same time, you may be feeling some emotions and forming some thoughts.

Together such experiences make up consciousness: the ojective & the subjective, inner life of the mind.
