The conscious mind and the brain were assumed to be separate entities. The intangible mind was lent to the ideals within theology. It was assumed that the conscious mind could not be measured (Descartes, 1641). This is an interesting thought because there were many mental differences or maladies at that time that were considered to be under the influence of insidious entities. Still, to this day, there are some tribal nations that consider those with symptoms of autism and other mental disorders to be under demonic influences. Those ideas also provide a basis for religion which would indicate that even after the body dies, the mind, or soul, lives on after that- the mind does not also die with the body.
