Rene Descartes invented a new way of learning, called methodological skepticism. He literally threw out every single piece of knowledge that came before him, and started from scratch. He doubted everything that he could not be sure of. There were only a few facts that Descartes could not doubt:
Statements such as "There is no such thing as a round square"
"Cogito ergo sum", latin for "I think therefore I am."
Probably a few other things which I cba to read up on again.
This is not a reality argument. This is a dualistic argument. He is giving credence to the existence of another self, a soul. He was able to doubt the existence of the world and of his body because we only experience those two things with our senses, which are fallible. He went on to say that everything one thought they knew were just various levels of belief, none of which can be said with actual truth as you can with the facts I listed.

Is there an immaterial soul (for lack of a better term) that gives credence to our unique ability of conceptual thought?
The extraordinary advances in investigative physics and biology have given scientists the false impression that they are approaching the point where whatever can be truthfully asserted about reality is within their grasp and that there is no room left for philosophy to add anything. ...(cont'd)... There are transempirical aspects of reality that cannot be scientifically investigated and measured. Stephen Hawking is egregiously in error when he asserts that what cannot be investigated and measured by physicists does not exist in reality.
@Ray: I would say that neurology and psychology are one and the same - they both look at the human mind, in different ways. Remember neurology is still in it's childhood, we don't know much yet, whereas psychology is an old, well worn area. I think in say, 50 years time, neurology will be able to explain in greater detail what psychology tries to explain. And even if they don't, neurology is still a child science, it's not really 'fair' or accurate to compare the two, when many breakthroughs are being founded every day in neurology, the lay of the land in that science is changing every day, so to speak.

To put in in context, Adler denounces Stephen Hawking for saying that everything that is not material/cannot be measured/cannot be empirically investigated as default-ly not existing.
So far, neurology has only answered questions concerning how the brain remembers, perceives, and imagines; just as Adler predicted the brain can only do. If neurology can answer why I can think conceptually, why I can think things that I have never perceived (concepts), then I would be able to say that there is no need for a soul.
Well, I'd say that neurology has the potential to answer those questions, not will. Based on current state of those sciences, you can't make a definite decision on what is a likely to be true, or which is the stronger argument, since I'd say it's not accurate to base evidence on an area of science that hasn't grown into it's prime yet, as I said before, in a couple of years there should be stronger evidence for this argument, for one or the other. =P

It must be material for it to exist, it must exist to do anything. Yet you say it is 'immaterial'. How would it be immaterial? How would it interact with a material world? The job of those arguments is to convince me that it is the better argument, and right now Monism is, to me. So convince me! =)
