“You remember what a fabulous success court-ordered "desegregation" plans have been. Few failures have been more spectacular. Illiterate students knifing one another between acts of sodomy in the stairwell is just one of the many eggs that had to be broken to make the left's omelette of transferring power from states to the federal government.”

The phrase "omlets are not made without breaking eggs" first appeared in English in 1796. It is from the French, "on ne saurait faire d'omelette sans casser des œufs" (1742 and earlier), attributed to François de Charette.

Context: You can not have omelettes without breaking eggs; you can not destroy the practises of barbarism, of slavery, of superstition, which for centuries have desolated the interior of Africa, without the use of force; but if you will fairly contrast the gain to humanity with the price which we are bound to pay for it, I think you may well rejoice in the result of such expeditions as those which have recently been conducted with such signal success in Nyassaland, Ashanti, Benin, and Nupé—expeditions which may have, and indeed have, cost valuable lives, but as to which we may rest assured that for one life lost a hundred will be gained, and the cause of civilization and the prosperity of the people will in the long run be eminently advanced.

People become more and more satisfied with the adoption, and if well administered, and administered with moderation they will cherish and bless those who have offered them a Constitution which will secure to them all the Advantages that flow from good government.

2000s, The Logic of the Colorblind Constitution (2004)
Context: Harlan's dissenting opinion in Plessy, that the Constitution was colorblind, and that it did not countenance different and unequal classes of citizens, was based upon a belief in the truth of the principle of equality in which the founders and Lincoln had so profoundly believed. But this belief had been buried by progressivism, and has not been resurrected, except by the intellectual heirs of Leo Strauss. On intellectual grounds, it has never been refuted, and ought never to have been abandoned. There is not now, and never has been any such difference between one human being and another human being, or whatever race or color, such that one is by nature the ruler of the other, as any human being is by nature the ruler of any dog or any horse. For this reason, legitimate political authority can arise only by the consent of the governed, and consent can never be given for any reason other than the equal protection of the rights of the governed. Hence equal protection is the foundation of all constitutionalism, even apart from its specific inclusion in the Constitution itself. For more reasons than one, Justice Harlan's dissenting opinion ought to have been the opinion of the Court in 1896; even more ought it to have been the opinion of the Court in 1954. As Professor Edward J. Erler has demonstrated in the pages of the Claremont Review of Books, the principle of equal protection has never become the opinion of the Supreme Court of the United States, nor has it been favored in the writings of conservative jurists.
