What is the Epistemological ground for believing the universal validity of the basic laws of logic (Identity, Non-Contradiction, Excluded Middle). How does one properly validate that "A is A", universally? Can one know that it is true universally or is it only possible to know it about that which one has perceived? If it is only possible to know it concerning that which has been perceived, then how can one know that "contradictions do not exist"? I do not question the validity of logic. However, the ground upon which one validates an idea is crucially important and it seems that Objectivists tend to ground the validity of logic in very intellectual dangerous territory-- such that if one takes Objectivist Epistemology seriously (or, at least, that which is professed by many parts of Oist Epistemology), one cannot also consistently take the laws of logic seriously. So, I want to test that out and reveal what is and is not the proper epistemological grounding for the validity of logic. Many (if not all) Objectivists hold that the validity of logic is grounded in perception (along with all other knowledge). However, if this is the case, one can only know it's validity concerning that which one has perceived. If one can know that it is valid concerning that which has not been perceived, where did this knowledge come from and upon what is it grounded? Is it simply believed as a pragmatic necessity? Is it assumed by whim or by faith? OR is there some other form of validating knowledge aside from perception? I obviously would argue that there is. I want to ask everyone who participates in this conversation to attempt to accurately understand what is (and is NOT) being said in order to avoid straw men, and that everyone attempt to be CONSISTENT with their professed views. I predict that most (if not all) objections will be the result of failing to do one of the above.
