Now nature herself teaches us what we should do. When we see in every day life things that are petty, ordinary, and banal, we generally fail to remember them, because the mind is not being stirred by anything novel or marvellous.
But if we see or hear something exceptionally base, dishonourable, unusual, great, unbelievable, or ridiculous -
That we are likely to remember for a long time.
