Forgetfulness is necessary to remembrance. Ideas are retained by renovation of that impression which time is always wearing away,and which new images are striving to obliterate. If useless thoughts could be expelled from the mind, all the valuable parts of our knowledge would more frequently recur, and every recurrence would reinstate them in their former place.
Samuel JohnsonNothing is more common than for men to make partial and absurd distinctions between vices of equal enormity, and to observe some of the divine commands with great scrupulousness, while they violate others, equally important, without any concern, or the least apparent conciousness of guilt. Alas, it is only wisdom which perceives this tragedy.
Samuel Johnson
