In the conclusion, throughout the paper I have described the psychological events to Cartesian dualism thesis, Rene Descartes' mind-brain problem and Qualitative Identity Theory, which helps one to understand why mind and the brain are distinct. The connection between the Cartesian Dualism and the Qualitative Identity Theory has been successfully stated with discussing psychological experiences, such as, the perception of looking at a house and the sense of feeling pain by touching the hot stove. For further arguments, another argument which can be made is that our minds and bodies are distinct because our bodies do not have a free will. an event that can given can be a person driving a vehicle. In this event their all body parts are doing different functions at same time. For example, hands on steering wheel, legs on break and accelerator, eyes looking at front and back side, and ears listening to horns and sirens and people shouting at them for stopping for long time on a signal. One can argue about this event comparing with our body having no free while this event is occurring. However, thought the arguments criticisms and explanation of theories and thesis using the folk psychological explanation of a particular behaviour and event; it is claimed that the mind (soul) and the body are two distinct substances.
