Truth Matters: Essays in Honor of Jacques Maritain (2004) asks whether one may derive an ought from purely descriptive premises.

Origin
Old English āhte became Middle English oughte. It was the past-tense form of āgan ("to own, possess") used for the first and third persons singular, so it amounts to owe plus -t. Sanskrit īśvará ("capable of, liable") is related.
