We learn most about people through the ear. We learn most about nature through the eye.
The great Jacob Bronowski, from The Visionary Eye. I don't know if this is true.

I worked with an actor once who said he was taught that 'speech is secondary'. He worked hard on his physicality, his psychological reasoning, and prided himself on throwing himself into the part. He was a bold, committed actor. He worked tirelessly. But I was surprised to find I didn't learn much about his character.
