 Anscombe compares moral teaching to mathematical teaching: in both cases, one must do something to truly learn what is being taught, rather than merely accepting something as to be believed. Teaching someone either morality or mathematics thus won’t just involve the formation of belief. Even so, she denies that a proper understanding of autonomy is incompatible with trusting moral testimony: deciding to trust someone who tells you about a bit of moral truth can be a way of thinking for oneself. A man who does this and acts on this testimony is still “his own pilot” (AIM, 49).
