By Father James V. Schall, S.J., The Catholic Thing - In The Idler for 21 October 1758, he wrote: "It has been the endeavor of all those whom the world reverenced for superior wisdom to persuade man to be acquainted with himself, to learn his own powers and his own weakness, to observe by what evils he is most dangerously beset, and by what temptations most easily overcome." This passage, no doubt, is simply Johnson's version of one of the Delphic maxims dear to Socrates: "Know thyself."
