 The sequence ‘received,’ ‘generally admitted’, and ‘intelligible’ corresponds to degrees of certainty for Avempace. The ‘received’ seems to be so from an authority of belief, the ‘generally admitted’ is that which qualifies the premisses of dialectical syllogisms, and the ‘intelligible’ is the direct apprehension of an object. The highest grade of assent belongs to the ‘received’, the ‘generally known’ to the intermediate degree, and the ‘intelligible’ to the lowest grade.
