What if absolutely everything is conscious?

If you’re feeling brave, sit and look — and I mean really look — at a plant on your windowsill as it bends toward the light. It seems simple, but stare at it long enough and you may find yourself doubting everything you thought you knew about your own mind.

Because sooner or later you’ll ask yourself: Why, exactly, is that plant stretching toward the sun?

Sure, you can look it up and find out there’s a thing called phototropism, which involves cells in a plant elongating to chase the sun.
