An nescis, mi fili, quantilla prudentia mundus regatur?
(Don't you know, my son, with how little wisdom the world is governed?)
This was supposedly written by the Swedish historical councellor Axel Oxienstierna in a letter to his son Johan in 1648.
Old men delight in giving good advice as a consolation for the fact that they can no longer provide bad examples.
François de La Rochefoucauld, Reflections; or Sentences and Moral Maxims (1665–1678), Maxim 93.
The hours of folly are measur'd by the clock, but of wisdom no clock can measure.
William Blake, The Marriage of Heaven and Hell (1790), Proverbs of Hell.
In this world everyone seems to have an opinion. But few seem to have the answers. You look around and think to yourself: What mystery lies within? Truth is elusive. But perhaps we should not look for the answers, but the right questions. And where are they not found better but in books? Great reading is not merely an escape from reality. It is a collision of two realities; of two worlds.
