[154] “As the Philosopher says at the beginning of the First Philosophy, ‘All men naturally desire to have knowledge.’ The reason of this may be that everything, being impelled by foresight belonging to its own nature, tends to seek its own perfection. Wherefore inasmuch as knowledge is the final perfection of our soul in which our final happiness consists, all men are naturally subject to the desire for it.” Conv. I. i. 1-11.
