The Art of Tetman Callis

“Caution is the best guard of tranquility. It is the most difficult thing in the world not to be upset when opinions which we hold, and to which we have given a too ready and too willful approval, are shattered by contrary arguments and are, as it were, weapons torn from our hands. It is a good thing to give in calmly to arguments that are well considered and grasped, just as it is dangerous to hold as known what in fact we do not know. We should be on our guard lest, when things are frequently undermined which we assumed would stand firm and abide, we fall into such hatred or fear of reason that we think we cannot trust even the most clearly manifest truth.” – Augustine of Hippo, The Teacher (trans. Burleigh)
