“The medievals distinguished between the intellect as ratio and the intellect as intellectus. Ratio is the power of discursive thought, of searching and re-searching, abstracting, refining, and concluding [cf. Latin dis-currere, ”to run to and fro”], whereas intellectus refers to the ability of ”simply looking” (simplex intuitus), to which the truth presents itself as a landscape presents itself to the eye. The spiritual knowing power of the human mind, as the ancients understood it, is really two things in one: ratio and intellectus, all knowing involves both. The path of discursive reasoning is accompanied and penetrated by the intellectus’ untiring vision, which is not active but passive, or better, receptive - a receptively operating power of the intellect.”
