Therefor, tis not in fact the thought that mandates the existance, but rather the thought of existance? Accordingly one might well think and exist but does one truely exist before the ponderance of one's own existance?
Is it the existance that is precluded by the thought or the thought that is precluded by the existance.
Hence Therefor:
we can postulate the idea of "I think, therfore I am" is nothing more then then the time told "Which came first, the Chicken or the egg"
