Pupils learn about common fallacies such as the ad hominem (personal attack), tu quoque (counter-attack) and post hoc, ergo propter hoc (mistaking correlation for causality), along with others derived from Aristotle’s Sophistical Refutations. The Latin may be off-putting, but in truth these are simple ideas which are readily digestible. If one were to discount arguments in which these fallacies were committed, virtually all online disputes would disappear.
