二元论：身体和心理是 separate
人与动物得区别
拥有心理是肯定的： i knew that i was a substance( 我知道我是个实体，),the whole essence or nature of which is to think,
(是思考主体的本质和本性) and that for its existence,(而这种思考主体的存在) there is no need of any place(无需任何空间)
nor does it depend on any material thing.(也不依赖于任何有形实体)
二元论是错误的：There is no "You" separable or separate from your body.In particular, there is no "You" separable from
your brain.
The mind is what the brain does. The mind reflects the workings of the brain just like computation
reflects the working of a computer.
大脑参与了心理活动，二元论否认了这一点。
