I recognize no such thing, since it's not a metaphysical "logical" matter but a dialectical one. No "meta-sensory apparatus" needed. As Marx put it: "The question whether objective truth can be attributed to human thinking is not a question of theory but is a practical question. Man must prove the truth, i.e., the reality and power, the this-sidedness of his thinking, in practice."
