“Determine never to be idle. No person will have occasion to complain of the want of time, who never loses any. It is wonderful how much may be done, if we are always doing.”

“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]” 

“To the corruptions of Christianity I am, indeed opposed; but not to the genuine precepts of Jesus himself. I am a Christian, in the only sense in which he wished any one to be; sincerely attached to his doctrines, in preference to all others.”

“I would rather be exposed to the inconveniences attending too much liberty, than those attending too small a degree of it.”

“القوة القانونية للحكومة يجب ان تتوقف على كبح الأفعال المؤذية للمواطنين تجاه الاخرين فقط . لا يوجد أذى لجارى ان قلت هناك أله واحد ، او هناك عشرين أله . هذا الفعل ليس سرقة لمحفظته او كسر لقدمه”

“In matters of principal stand like a rock.”

“The most fortunate of us, in our journey through life, frequently meet with calamities and misfortunes which may greatly afflict us; and, to fortify our minds against the attacks of these calamities and misfortunes should be one of the principal studies and endeavors of our lives. The only method of doing this is to assume a perfect resignation to the Divine will, to consider that whatever does happen, must happen; and that, by our uneasiness, we cannot prevent the blow before it does fall, but we may add to its force after it has fallen. These considerations, and others such as these, may enable us in some measure to surmount the difficulties thrown in our way; to bear up with a tolerable degree of patience under the burden of life; and to proceed with a pious and unshaken resignation, till we arrive at our journey's end.”

“I felt enough of the effect of withdrawing from the world then, to see that it led to an antisocial and misanthropic state of mind, which severely punished him who gives in to it. And it will be a lesson I never shall forget as to myself.”

“The clause too, reprobating the enslaving the inhabitants of Africa, was struck out in complaisance to South Carolina and Georgia, who had never attempted to restrain the importation of slaves, and who on the contrary still wished to continue it. Our northern brethren also I believe felt a little tender under those censures; for tho' their people have very few slaves themselves yet they had been pretty considerable carriers of them to others.”
