"How do you create the conditions in which we can sense and feel ourselves?"
-David Zemach-Bersin

Here is a lecture from 2013 by David Zemach-Bersin where he introduces the idea of the Weber Fechner Law.

More quotes from the video:

"Most of us are not aware of what we're doing. We're even less aware of how we do what we do..."

"There's a relationship between tonus (muscular activity) and emotion or mood."

"Our brain is acting in our behalf."

"Muscular effort creates noise."

"There's an inverse relationship between effort and our ability to feel."

"My ability to feel a difference is dependent on the intensity of the work I'm doing."

"The more your reduce the intensity of the work (or the stimulus) the more sensitive you become to differences."

"In order to do what I want, I need to know what I'm doing. In order to know what I'm doing, I need to be able to feel myself."
