For his theory of knowledge is, that it is the natural and innate desire of the soul, as essential to its own perfection in its ultimate union with God. The use of the reason, through which he partakes of the Divine nature, is the true life of man. Its right use in the pursuit of knowledge leads to philosophy, which is, as its name signifies, the love of wisdom, and its end is the attainment of virtue. It is because of imperfect knowledge that the love of man is turned to fallacious objects of desire, and his reason is perverted. Knowledge, then, is the prime source of good; ignorance, of evil. Through knowledge to wisdom is the true path of the soul in this life on her return to her Maker, to know whom is her native desire, and her perfect beatitude. In the exposition of these truths in their various relations a multitude of topics of interest are touched upon, and a multitude of opinions expressed which exhibit the character of Dante's mind and the vast extent of the acquisitions by which his studies had enriched it. The intensity of his moral convictions and the firmness of his moral principles are no less striking in the discourse than the nobility of his genius and the breadth of his intellectual view. Limited and erroneous as are many of his scientific conceptions, there is little trace of superstition or bigotry in his opinions; and though his speculations rest on a false conception of the universe, the revolting dogmas of the common mediaeval theology in respect to the human and the Divine nature find no place in them. The mingling of fancy with fact, the unsoundness of the premises from which conclusions are drawn, the errors in belief and in argument, do not affect the main object of his writing, and the 'Convito' may still be read with sympathy and with profit, as a treatise of moral doctrine by a man the loftiness of whose intelligence rose superior to the hampering limitations of his age.
