If, then, it is just becoming understood how electrical impulses affect the mind, could there not be some kind of continued electrical activity after death that somehow continues to support that mind? What of the newest discoveries in the field of matter? What of quarks? Is it not true that science is just beginning the study of a vast new world of particles and energy that defies previous thought? If science can change so radically concerning the very nature of matter and how it behaves, is it not possible that the nature of life and mind activity can also change?

            

             Thus, to believe that it will not change, that science has uncovered all there is to know about the nature of life and existence, as well as the boundaries for that existence (namely, death), involves the same kind of faith in the unknown (after all, no one knows where science will lead) that an intense faith in the infinite soul entails. Interestingly, however, scientific atheists (or others who do not believe in life after death), purport to use reason and reason alone in their theories of body-based temporal existence. Yet this is a problem, just as much as it is a problem in mind-based theories, specifically in the kind exemplified by Descartes" "I Think, Therefore I am" premise.

             I Think, Therefore I Am-I Think.

             Many people, like the great Descartes believed that the mere presence or existence of thought is enough to prove the existence of a mind based identity. According to him, every bit of information available from outside sources comes from one of the senses. As such, all information gleaned through these sources cannot be trusted, simply because the senses can be fooled (as in the famous Wax Argument). Although all outside input is suspect, there is one constant, and that is the presence of thought. Although the product of thought (namely, conclusions), cannot be trusted or used to base ideas of identity or truth, the fact that one is thinking (however flawed that thinking may be), indicates one"s existence.
