"Any one may so arrange his affairs that his taxes shall be as low as possible; he is not bound to choose that pattern which will best pay the Treasury; there is not even a patriotic duty to increase one's taxes." - Learned Hand, in Helvering v. Gregory, 1934.
"Over and over again courts have said that there is nothing sinister in so arranging one's affairs as to keep taxes as low as possible. Everybody does so, rich or poor; and all do right, for nobody owes any public duty to pay more than the law demands: taxes are enforced exactions, not voluntary contributions. To demand more in the name of morals is mere cant." - Learned Hand, in Commissioner v. Newman, 1947.
"My friends, will you not agree that any society which begins to be doubtful of itself; in which one man looks at another and says: "He may be a traitor," in which that spirit has disappeared which says: "I will not accept that, I will not believe that—I will demand proof. I will not say of my brother that he may be a traitor," but I will say, "Produce what you have. I will judge it fairly, and if he is, he shall pay the penalties; but I will not take it on rumor. I will not take it on hearsay. I will remember that what has brought us up from savagery is a loyalty to truth, and truth cannot emerge unless it is subjected to the utmost scrutiny"—will you not agree that a society which has lost sight of that, cannot survive?" - Learned Hand, retired Chief Judge of the United States Court of Appeals for the Second Circuit
