Ego autem difficillime bonus iudex lego quod scripserim, sed aut timidior recto aut cupidior. Video etiam interdum vitia mea, sed haec malo audire a melioribus, ne, cum me recte fortasse reprehendero, rursus mihi blandiar et meticulosam potius mihi videar in me quam iustam tulisse sententiam.
Augustinus Hipponensis, Ep. 28.4, ad Sanctum Hieronymum
Moreover I find it very difficult to be a good judge when I read what I have written, but I am either too timid or too eager. Still, sometimes I see my flaws, but I prefer to hear about them from better men, lest, whenever I perhaps catch myself rightly, I should turn around and flatter myself and seem to myself to have passed on myself a meticulous rather than a just sentence.
St Augustine of Hippo, Letter 28.4, to Saint Jerome
This is why anyone who seeks to proceed upon the path of self-perfection needs a director, for, as a wise man once said, the body is an untrustworthy friend who must be given a little less than he asks for, or he will turn traitor.
Thanks, dear reader, should you ever find me, for being my gadfly.
