The Guide for the Perplexed
In "The Guide for the Perplexed", Maimonides argues that the story of the binding of Isaac contains two "great notions". First, Abraham's willingness to sacrifice Isaac demonstrates the limit of humanity's capability to both love and fear God. Second, because Abraham acted on a prophetic vision of what God had asked him to do, the story exemplifies how prophetic revelation has the same truth value as philosophical argument and thus carries equal certainty, notwithstanding the fact that it comes in a dream or vision.
