Augustine, Confessions §aug_conf_10_062: Behold, in Thee, O Truth, I see that I ought not to be moved at my own praise...
Behold, in Thee, O Truth, I see that I ought not to be moved at my own praises, for my own sake, but for the good of my neighbour. And whether it be so with me, I know not. For herein I know less of myself than of Thee. I beseech now, O my God, discover to me myself also, that I may confess unto my brethren, who are to pray for me, wherein I find myself maimed. Let me examine myself again more diligently. If in my praise I am moved with the good of my neighbour, why am I less moved if another be unjustly dispraised than if it be myself? Why am I more stung by reproach cast upon myself, than at that cast upon another, with the same injustice, before me? Know I not this also? or is it at last that I deceive myself, and do not the truth before Thee in my heart and tongue? This madness put far from me, O Lord, lest mine own mouth be to me the sinner's oil to make fat my head. I am poor and needy; yet best, while in hidden groanings I displease myself, and seek Thy mercy, until what is lacking in my defective state be renewed and perfected, on to that peace which the eye of the proud knoweth not.
