"The man within the breast, the abstract and ideal spectator of our sentiments and conduct, requires often to be awakened and put in mind of his duty, by the presence of the real spectator: and it is always from that spectator, from whom we can expect the least sympathy and indulgence, that we are likely to learn the most complete lesson of self-command."
— Smith, Adam (1723-1790)
