The justification of the sceptical method of doubting is too shaky to accept. The body was matter and all matter was simply extension, inertia moved by other things or describable in terms of space, depth, distance or length.
This is a mental event which will cause a physical event surely? The second issue we have is the issue of interactionism. In his work Meditations Descartes outlines the fact that his body is divisible. He demonstrates this mistake through several examples: However, the Functionalist Putnam might argue that at least in terms of pain we are similar enough in experiences for this criticism to stand.
This led him to believe that the mind and body were separate as he could imagine his mind without a body. He suggested that he may be being deceived by an evil deceiver but stressed that he had the concept of God as a supremely perfect being implanted in his mind.
The argument is fallacious as the concept of God in his mind relies on his mental faculties being correct and his mental faculties rely on the concept of God not being some evil deceiver.
It is as though these two separate tracks run in parallel. Descartes was a substance dualist and a product of the renaissance. There are obvious problems with this.
Yet it still seems as though our subjective experience of mind or consciousness continues to defy full explanation. It was not in motion but simply an indivisible thinking thing. There is no causal relationship between mind and body for Leibniz and Malebranche as God is responsible for either setting up the two independent realities Pre-established Harmony or acting in each individual occasion Occasionalism.
This is a physical gland in the brain which he argues is indivisible unlike the rest of the body as indicated by the senses which come in pairs. He believed that the body and soul were two different substances.
It seems obvious that I can cause physical things to happen and that my body has an effect on me. The official doctrine as Ryle puts it, is just as Descartes describes, a separate substance for mental events and physical events.
I am thinking about taking a sip of Green tea and Jasmine as I write.
The last issue on interactionism comes through work following that of Descartes in the guise of Pre-established Harmony and Occasionalism. Moreover, Descartes believed that God could do the logically impossible so it is plausible in this view, that God could be deceiving his faculties in to believing his thoughts are accurate.
Rather like a ghost riding a bike it seems as though the mind is causally impotent. These examples demonstrate that the mind is like a ghost in the machine, an extra entity attributed when none is needed.
Zinn argued that the brain is fully divisible after split brain experiments on dogs. Descartes began the method of doubt. Secondly he seems to forget that we only have one tongue as a sense organ. The logical problem arising from this was his contention that the mind could be separate from the body.
His mind was a single thinking thing, capable of doing other than that which the body desired. They both argue that the substance dualism Descartes outlines is correct. There is a relationship between the physical and mental but this does not necessarily mean that they are entirely separate as Ryle explains.
We shall begin with the logical problems. This is known as the Cartesian Circle. The argument is therefore circular and so fails. Yet this seems to be counter-intuitive. I hope you find it useful.

Descartes believed that the mind and body were two distinct substances: The pineal gland is capable of single thought and so he concludes this is the link between the body and mind. He was influenced by Aristotle and the Christian world view.
This res extensa required something else to move it. Since God, being perfect, could not deceive him he could trust his mental faculties. It had no place in the spacio-temporal world.
The issue surrounds how the two substances could be seen to interact.Mental events and physical events are not distinct in this view which directly challenges Descartes’ substance dualism. However Ryle isn’t suggesting a materialist view necessarily, rather that the notion of consciousness or intentionality is more complex than dualism or materialism might suggest.
When Descartes published his ideas in his Meditations on First Philosophy, his ideas were not new, but nonetheless groundbreaking. He proposed there were two separate types of matter or stuff that can exist independent of each other. These are physical substances and mental substances.
The physical. One is Substance dualism which holds that the mind or soul is a separate, non-physical entity, but there is also property dualism, according to which there is no soul distinct from the body, but only one thing, the person, that has two irreducibly different types of properties, mental and physical.
In this essay I will outline Descartes’ main arguments, The foundation of Cartesian dualism is that there are two different types of substances: physical and mental.1 Physical substances have the fundamental property of extension while mental substances have the fundamental property of thought.
Descartes was a dualist in that he beleived in two distinct substances: mental and physical.
For him our bodies were physical machines that operated by the laws of physics. For instance, a person moves her arm from a fire because the fire pulls on a string attached to her brain, which in turn pulls a string attached to her muscle causing it to.
