Ante-Nicene Fathers, Vol VIII:
Pseudo-Clementine Literature.: Chapter IV

p. 144 Chapter IV.—Ignorance the Mother of Evils.

“From 753 all these things, therefore, it is concluded that all evil springs from ignorance; and ignorance herself, the mother of all evils, is sprung from carelessness and sloth, and is nourished, and increased, and rooted in the senses of men by negligence; and if any one teach that she is to be put to flight, she is with difficulty and indignantly torn away, as from an ancient and hereditary abode.  And therefore we must labour for a little, that we may search out the presumptions of ignorance, and cut them off by means of knowledge, especially in those who are preoccupied with some erroneous opinions, by means of which ignorance is the more firmly rooted in them, as under the appearance of a certain kind of knowledge; for nothing is worse than for one to believe that he knows what he is ignorant of, and to maintain that to be true which is false.  This is as if a drunk man should think himself to be sober, and should act indeed in all respects as a drunk man, and yet think himself to be sober, and should wish to be called so by others.  Thus, therefore, are those also who do not know what is true, yet hold some appearance of knowledge, and do many evil things as if they were good, and hasten destruction as if it were to salvation.
