Hearing colors and seeing sounds

Synaesthesia, is a rare condition in which a stimulus received in one sense organ causes an experience in another. For example, in colored hearing, sound and vision may mingle: the different tones of words and letters can involuntarily evoke distinct and vivid colors.

Cells and Sympathy

Charles Hartshorne espoused the view that our cells and our conscious selves feel each other through sympathy. For example, here is a quote from this article:

"Take the case of pain. We have this feeling if certain cells of ours undergo damage. But if the cells have their own feelings, they can hardly enjoy being damaged. So what is our suffering but our participating in their suffering? Hurt certain of my cells and you hurt me."

The Philosophy of Smell

Whitehead argued that theories of consciousness often flounder because they explain what is most primitive and basic in terms of what stands out most clearly and distinctly. In contemporary times, a similar argument could be made that attempts to explain or understand experience in terms of it's more complex accomplishments (such as thought, computational ability, cognition, or language) are starting at the wrong place.

This post will primarily be concerned with the question of whether the brain, sense organs and nerve cells are necessary for perception.
