"With regard to man, his immaterial spirit is also free; but it is most at liberty, when employed in the contemplation of the divine mind; it becomes less so, when it enters into a body; and is still more restrained, when it is imprisoned in a terrestrial habitation, composed of members of clay; and is reduced, in fine, to the most extreme servitude, when by plunging into the pollutions of vice, it totally departs from reason: for the soul no sooner turns her eye from the radiance of supreme truth, to dark and base objects, but she is involved in a mist of ignorance, assailed by impure desires; by yielding to which, she encreases her thraldom; and thus the freedom which she derives from nature, becomes in some measure the cause of her slavery."
