Those, then, who have no desire for either discovery or investigation have shamefully debased their reason by ignorance and indifference, and though they had it in their power to see acutely, they have become blind. Thus he says that "Lot’s wife turning backwards became a pillar of salt;" Genesis xix. 26 not here inventing a fable, but pointing out the proper nature of the event.
 For whoever despises his teacher, and under the influence of an innate and habitual indolence forsakes what is in front of him, by means of which it may be in his power to see, and to hear, and to exert his other powers, so as to form a judgment in things of nature, and turns his head round so as to keep his eyes on what is behind him, that man has an admiration for blindness in the affairs of life, as well as in the parts of the body, and becomes a pillar, like a lifeless and senseless stone. For, as Moses says, "such men have not hearts to understand, nor eyes to see, nor ears to hear," Deut. xxix. 4. but make the whole of their life blind, and deaf, and senseless and mutilated in every respect, so as not to be worth living, caring for none of those matters which deserve their attention.
