“If your proof is insubstantial, you might instead begin with a vehement refutation in the hope that no one notices your lack of argument. Since Plato’s Phaedo, and even a little before, the Western mind has been marked by deep divisions or dualities, such as soul and body, mind and matter, reason and sense experience, reason and emotion, reality and appearance, good and evil, heaven and hell. This binary thinking carries over to dialectic and rhetoric, in which it is often one thing or the other, rather than both or several or neither. Thus, in the Western mind, knocking down your opponent’s argument is tantamount to validating your own. Notice that the very concept of a debate with an ‘opponent’ is confrontational, when the exercise could instead be cooperative and conversational, as in the Upanishads.”
