We have been considering the essence of Aquinas' teachings about our spiritual journey toward wisdom and justice and compassion and away from dullness and indifference and, in his words, folly. He says: "Folly implies apathy in the heart and dullness in the senses...For sapiens (wise) as Isidore says 'is so named from sapor (savor), because just as the taste is quick to distinguish between savors of meats, so too a wise person is quick in discerning things and causes.' Thus it is clear that folly is opposed to wisdom as its contrary...the fool has the sense, though dulled, whereas the wise person has the sense acute and penetrating."
