“Jesus knew when it was about time for Him to go to the cross. In John 14:30 He actually said to His disciples, I will not talk with you much more, for the prince (evil genius, ruler) of the world is coming. And he has no claim on Me. [He has nothing in common with Me; there is nothing in Me that belongs to him, and he has no power over Me.]”

“Every day is lost in which we do not learn something useful. Man has no nobler or more valuable possession than time.”

“To your request of my opinion of the manner in which a newspaper should be conducted, so as to be most useful, I should answer, ‘by restraining it to true facts & sound principles only.’ Yet I fear such a paper would find few subscribers. It is a melancholy truth, that a suppression of the press could not more compleatly deprive the nation of its benefits, than is done by its abandoned prostitution to falsehood. Nothing can now be believed which is seen in a newspaper. Truth itself becomes suspicious by being put into that polluted vehicle. The real extent of this state of misinformation is known only to those who are in situations to confront facts within their knolege with the lies of the day. I really look with commiseration over the great body of my fellow citizens, who, reading newspapers, live & die in the belief, that they have known something of what has been passing in the world in their time; whereas the accounts they have read in newspapers are just as true a history of any other period of the world as of the present, except that the real names of the day are affixed to their fables. General facts may indeed be collected from them, such as that Europe is now at war, that Bonaparte has been a successful warrior, that he has subjected a great portion of Europe to his will, &c., &c.; but no details can be relied on. I will add, that the man who never looks into a newspaper is better informed than he who reads them; inasmuch as he who knows nothing is nearer to truth than he whose mind is filled with falsehoods & errors. He who reads nothing will still learn the great facts, and the details are all false.” —Letter to John Norvell, 14 June 1807 [Works 10:417--18]”

“You're not racing?" joked the officer. "Mine is a harder race," Alexei Alexandrovich replied respectfully. And though the reply did not mean anything, the officer pretended that he had heard a clever phrase from a clever man and had perfectly understood.”
