" Human souls must needs be comparatively free while they abide in the contemplation of the Divine mind, less free when they pass into bodily form, and still less, again, when they are enwrapped in earthly members. But when they are given over to vices, and fall from the possession of their proper reason, then indeed their condition is utter slavery. For when they let their gaze fall from the light of highest truth to the lower world where darkness reigns, soon ignorance blinds their vision; they are disturbed by baneful affections, by yielding and assenting to which they help to promote the slavery in which they are involved, and are in a manner led captive by reason of their very liberty. "
