Man enjoins himself to be necessarily in fault: he is not very discreet to cut out his own duty by the measure of another being than his own.

Context

“We are so far from being good men, according to the laws of God, that we cannot be so according to our own human wisdom never yet arrived at the duties it had itself prescribed; and could it arrive there, it would still prescribe to itself others beyond, to which it would ever aspire and pretend; so great an enemy to consistency is our human condition. Man enjoins himself to be necessarily in fault: he is not very discreet to cut out his own duty by the measure of another being than his own. To whom does he prescribe that which he does not expect any one should perform? is he unjust in not doing what it is impossible for him to do? The laws which condemn us not to be able, condemn us for not being able.” source
