— The Feynman Lectures on Physics”
Hello Susan, Ray, Justin, Descartes “I think therefore I am” represents a perception of an irreducible activity of mind, I.e., the energy of thinking. As per the quote from Feynman above, this is completely in line with contemporary physics. Thinking is an activity, it is energy doing stuff, again thinking. We think, we apply our thinking to the analysis of stuff “out there”. Matter.
Even though many philosophers and scientists think there is some way to make energy and matter equivalent, they just can’t. Understanding the world as energy and matter is what we call physics or physical reality. Descartes fits right in with this modern viewpoint as energy cannot be reduced to matter, nor matter to energy. When we say that ‘thinking’ is part of our homo sapient brains, we are saying that our brains are composed of matter and energy. And thinking is the result.
From a physicist perspective, we cannot rule out dualism. Matter and energy are simply the basis of the world we can think and know. IMO, of course.
