The question: how to fit human conception to real world principles

the nature of mind

fundamental theories: atomic physics and evolutionary biology

Descartes:

dualism：mind-mental substance ;body-physical substance

Essence of mind: conscious, always thinking ;=soul

property: free; directly understand by

reflecting

Essence of body: extension, occupy, no mentality

property: limited to physics

I think therefore I exist

conclusion: mind stuck in the body

Although it can’t be true, general public agree to it;

E.g: vision：you see a object- actually the object affects my nervous system and you see a picture in your mind; relation of the object and the picture?

No direct knowledge of the reality but of the perception

The relationship between the mind and body, body control, feeling

we can feel our mental state, but not others
