 Tsongkhapa argues that a negation of all four extremes at the ultimate level defies logic, but Gorampa contends that a transcendence of logic is specifically the tetralemma’s purpose. By negating all possibilities for logical, conceptual thought, the only recourse is to abandon concepts completely. True freedom from conceptual proliferations lies outside of the scope of conceptual thought, and is therefore inexpressible. Gorampa maintains, however, that because ordinary persons utilize conceptual thought, they necessarily construe the ultimate truth as an object of conceptual constructs (that is, they construe it as the ultimate that is taught). As such, one must first use conceptual reasoning to refute each of the four extremes, but these concepts must eventually be abandoned.
