[Something] does not rise to the dignity of error.

After an error you need not only to remove the causes but also to correct the error itself: after a sin you must not only, if possible, remove the temptation, you must also go back and repent the sin itself. In each case an 'undoing' is required.

Every uncorrected error and unrepented sin is, in its own right, a fountain of fresh error and fresh sin flowing on to the end of time.

The true reader reads every work seriously in the sense that he reads it whole-heartedly, makes himself as receptive as he can. But for that very reason he cannot possibly read every work solemly or gravely. For he will read 'in the same spirit that the author writ.'... He will never commit the error of trying to munch whipped cream as if it were venison.
