Abstract

The paper addresses three main issues drawing on Husserl’s writings on logic. First, what gives the logical objects their objective status, given the fact that these are intimately connected with human mental processes? Second, if logical objects are objective then how is logical knowledge at all possible? The answer to this question leads to a transcendental foundation of formal logic. Third, how do the principles of logic apply to the real world? This question can be addressed by positing a formal ontology. Against Russell and Whitehead, it has been pointed out that even if logical implication does not in any way depend on human mind, inference is definitely mind-dependent. But this thesis does not necessarily lead to psychologism, as has been pointed out by contemporary Indian logicians. Indian theories of inference deal with the question of truth and falsity but lack a formal ontology. Both pure logic and modern physics claim to be independent of human existence. This claim becomes evident in the conversation between Heisenberg and Tagore. Husserl had distinguished between logical grammar and logic of consequences. The notions of truth and falsity are relevant only in the context of logic of consequences. However, none of the well-known theories of truth, correspondence, coherence or pragmatic theory is free from defects. Following in the footprints of the Advaita Vedantins, it has been maintained that falsity is more fundamental than truth. In the process of cognitive history, a proposition is taken to be true, unless its falsity is proven. Hence the conclusion: since Philosophy is search for the truth, all Philosophy—infinitely—is a gradual rejection of all claims to truth and finally, destroys itself.
