What is consciousness for?

In 2015 I was invited to write a short piece on consciousness for the magazine Aeon. The text now appears to be unavailable on Aeon, so I am reposting it here. From the moment we wake we are bombarded with stimuli. Electromagnetic radiation floods our eyes, pressure waves hit our ears, surfaces press against our skins, molecules adhere to the membranes of our noses and tongues. Our sense organs react, sending nerve impulses to our brains, where they trigger waves of neural activity, which may culminate in motor commands to our muscles (shielding our eyes from the light, for example).

Later, one person (not themselves trans, I believe) wrote to say that they felt such images were disrespectful to trans women. They were polite and didn’t ask me to remove the image. However, I became concerned that some trans women might think I was mocking them, and I decided to delete the image, just […]
