“The force which makes for war does not derive its strength from the interested motives of evil men; it derives its strength from the disinterested motives of good men.”

Quote, First State of the Union Address (1865)
Context: Our Government springs from and was made for the people — not the people for the Government. To them it owes allegiance; from them it must derive its courage, strength, and wisdom. But while the Government is thus bound to defer to the people, from whom it derives its existence, it should, from the very consideration of its origin, be strong in its power of resistance to the establishment of inequalities. Monopolies, perpetuities, and class legislation are contrary to the genius of free government, and ought not to be allowed. Here there is no room for favored classes or monopolies; the principle of our Government is that of equal laws and freedom of industry. Wherever monopoly attains a foothold, it is sure to be a source of danger, discord, and trouble. We shall but fulfill our duties as legislators by according "equal and exact justice to all men," special privileges to none.

"Political Correctness: Robert Bly and Philip Larkin" (1997)
Context: The reaction against Larkin has been unprecedentedly violent as well as unprecedentedly hypocritical, tendentious and smug. Its energy does not, could not derive from literature — it derives from ideology, or from the vaguer promptings of a new ethos. … This is critical revisionism in an eye-catching new outfit. The reaction, like most reactions, is just an overreaction, and to get an overreaction you need plenty of overreactors — somebody has to do it. … I remember thinking when I saw the fiery Tom Paulin's opening shot, We're not really going to do this, are we? But the new ethos was already in place, and yes, we really were going to do this — on Paulin's terms, too. His language set the tone for the final assault and mop-up, which came with the publication of Andrew Motion's, Philip Larkin: A Writer's Life. Revolting. Sewer. Such language is essentially unstable. It calls for a contest of the passions and hopes that the fight will get dirty.
