Chronic remorse

Chronic remorse, as all the moralists are agreed, is a most undesirable sentiment. If you have behaved badly, repent, make what amends you can and address yourself to the task of behaving better next time. On no account brood over your wrongdoing. Rolling in the muck is not the best way of getting clean.

Art also has its morality, and many of the rules of this morality are the same as, or at least analogous to, the rules of ordinary ethics. Remorse, for example, is as undesirable in relation to our bad art as it is in relation to our bad behaviour. The badness should be hunted out, acknowledged and, if possible, avoided in the future. To pore over the literary shortcomings of twenty years ago, to attempt to patch a faulty work into the perfection it missed at its first execution, to spend one’s middle age in trying to mend the artistic sins committed and bequeathed by the different person who was oneself in youth—all this is surely vain and futile.
