My question is: If the laws of logic and reasoning may be merely personal constructs, how can one even know that one has a mind?
Descartes' justification for knowing that he possessed, at the least, a mind rested on the logical argument that one must have a mind in order to think. Sensory evidence alone is not sufficient to lead to such a conclusion, even if one is inclined to place faith in such evidence, which both Descartes and Glasersfeld are apparently not. In order to reach this conclusion, one requires logic, or reasoning - which Glasersfeld suggests may be constructs only. As such, I conclude that according to the theory of radical constructivism, one cannot know that one has a mind. Combined with my previous post regarding humans' abilities to know about objects and concepts, I also conclude that radical constructivism precludes one from knowing anything at all.
