"The issue is not debate, simpliciter, but how it is done. Too many philosophers accept the idea that truth is best achieved by a marketplace of ideas conducted in the fashion of ultimate fighting. But aggressive styles that seek easy victories by harping on arcane counterexamples do not maximize truth. Nor does making use of the social advantages one might have by virtue of one’s gender, ethnicity or seniority. Nor does stubbornly refusing to acknowledge the real world contexts, rife with implicit bias and power distortions, in which even philosophical debates always occur.
Sometimes, interestingly, the aim of truth is enhanced less by adversarial argument than by a receptivity that holds back on disagreement long enough to try out the new ideas on offer, push them further, see where they might go. Sometimes pedagogy works best not by challenging but by getting on board a student’s own agenda. Sometimes understanding is best reached when we expend our skeptical faculties, as Montaigne did, on our own beliefs, our own opinions. If debate is meant to be a means to truth — an idea we philosophers like to believe — the best forms turn out to be a variegated rather than uniform set."
