"It is now time, leaving every object of sense far behind, to contemplate, by a certain ascent, a beauty of a much higher order; a beauty not visible to the corporeal eye, but alone manifest to the brighter eye of the soul, independent of all corporeal aid. However, since, without some previous perception of beauty it is impossible to express by words the beauties of sense, but we must remain in the state of the blind, so neither can we ever speak of the beauty of offices and sciences, and whatever is allied to these, if deprived of their intimate possession. Thus we shall never be able to tell of virtue's brightness, unless by looking inward we perceive the fair countenance of justice and temperance, and are convinced that neither the evening nor morning star are half so beautiful and bright. But it is requisite to perceive objects of this kind by that eye by which the soul beholds such real beauties. Besides it is necessary that whoever perceives this species of beauty, should be seized with much greater delight, and more vehement admiration, than any corporeal beauty can excite; as now embracing beauty real and substantial. Such affections, I say, ought to be excited about true beauty, as admiration and sweet astonishment; desire also and love and a pleasant trepidation. For all souls, as I may say, are affected in this manner about invisible objects, but those the most who have the strongest propensity to their love; as it likewise happens about corporeal beauty; for all equally perceive beautiful corporeal forms, yet all are not equally excited, but lovers in the greatest degree."

“An Essay on the Beautiful" as translated into English by Thomas Taylor”

“It is by participation of species that we call every sensible object beautiful. Thus, since everything void of form is by nature fitted for its reception, as far as it is destitute of reason and form it is base and separate from the divine reason, the great fountain of forms; and whatever is entirely remote from this immortal source is perfectly base and deformed. And such is matter, which by its nature is ever averse from the supervening irradiations of form. Whenever, therefore, form accedes, it conciliates in amicable unity the parts which are about to compose a whole; for being itself one it is not wonderful that the subject of its power should tend to unity, as far as the nature of a compound will admit. Hence beauty is established in multitude when the many is reduced into one, and in this case it communicates itself both to the parts and to the whole. But when a particular one, composed from similar parts, is received it gives itself to the whole, without departing from the sameness and integrity of its nature. Thus at one and the same time it communicates itself to the whole building and its several parts; and at another time confines itself to a single stone, and then the first participation arises from the operations of art, but the second from the formation of nature. And hence body becomes beautiful through the communion supernally proceeding from divinity.”

“When the soul has descended into generation she partakes of evil, and is carried a great way into a state the opposite of her first purity and integrity, to be entirely merged in which, is nothing more than to fall into a dark mire. ...The soul dies as much as it is possible for the soul to die: and the death to her is, while baptized or immersed in the present body, to descend into matter, and be wholly subjected by it; and after departing thence to lie there til it shall arise and turn its face away from the abhorrent filth. This is what is meant by falling asleep in Hades, of those who have come there.”
