We often do evil, and do worse in excusing ourselves.
We are sometimes moved with passion, and we think it to be zeal.
We reprehend small things in others, and pass over greater matters in ourselves.
We quickly enough feel and weigh what we suffer at the hands of others; but we mind not what others suffer from us.
He that doth well and rightly consider his own works, will find little cause to judge harshly of another.
- Thomas a Kempis, The Imitation of Christ
