we might be woken up by a loud sound, but after we wake up we might not remember a thing. It still remains that even though we can't remember any thought before we wake, we know that there was because we heard the noise and woke up. We still have experiences while asleep whether they are dreams or experience of hot or cold or a smell or a sound. We know we still experience them because they arouse us to wakefulness and therefore are experience while in deep sleep. Therefore, it is possible that while in deep sleep we might not remember everything we thought but we are still thinking or else we would probably never wake up. Think about how you wake up at any time and it is obvious that some thought is involved. And the wakefulness by loud sound or disturbance is also called reaction but not the interaction of body and mind. Mind is conscious and non-spatial and body is spatial but not conscious. While separate, these two substances interact. The mind, which can't be doubt or divided or extended, no shape but it is to think in the pursuit of knowledge and the body, in return, can be doubt, divided, extended, occupied space, is a place containing brain that generates thought. Descartes asserts that the mind and body are separable and infinite by using his method of doubt to show that he could not doubt the existence of his mind. As long as we think, we are existing because we must exist first then to think. As doubting involved thought, and thought needs a consciousness to think it, Descartes was sure that he could not doubt his mind existed: "I think therefore I am". He claims to know what a thinking think is, and he regards we are as thinking thing. The Cartesian Dualism is still having problem of explanation of how mind and body interact or why mind does not stuck in body or mind control body. Insisting that the mental representation does not represent the physical is very confused and does not completely explain the issues. Descartes ...
