The Extended Mind Hypothesis

The Extended Mind Hypothesis does exactly what it says on the tin. It is a theory suggesting that the human mind is not necessarily limited to a mental capacity. According to Clark and Chalmers the mind can extend to include information storage devices (such as computers, diaries, or even other peoples minds) to which we can have ready access, can rely on and trust as we would our own minds. These devices would be in a similar mode or state as the subconscious mind, that is; they would embody dispositional beliefs. This is known as active externalism.

Clark and Chalmers begin with a case to illustrate why the mind is extended whereby a person has the option to use their mind (a), use a physical computational aid (b), or a futuristic neural computational brain implant (c) to solve a problem. They argue that all three options are more similar than most people believe with the following reasoning. I have included the example of a heart, a defibrillator and pacemaker for the sake of clarity.

The mental (a) and computational processes (c) are the similar in that they do the same job, and both occur internally. They could be analogised to a heart and a pacemaker.
A physical aid (b) and a neural implant (c) are the similar in that they both have a computational structure. They could be analogised to a defibrillator and pacemaker.
By this reasoning (a) and (b) must also be the similar.

With this notion, Clark and Chalmers try to establish an interactive cognitive link between humans and external entities, thus showing how it is the system between the two makes up the mind - both the internal and external components are vital parts of the mind. In this essay, I shall oppose this view by revealing firstly, a fallacy and Clark and Chal...
