“The doctrine that all men are, in any sense, or have been, at any time, free and equal, is an utterly baseless fiction.”

This charge of inferiority is an old dodge. It has been made available for oppression on many occasions. It is only about six centuries since the blue-eyed and fair-haired Anglo Saxons were considered inferior by the haughty Normans, who once trampled upon them. If you read the history of the Norman Conquest, you will find that this proud Anglo-Saxon was once looked upon as of coarser clay than his Norman master, and might be found in the highways and byways of Old England laboring with a brass collar on his neck, and the name of his master marked upon it were down then! You are up now. I am glad you are up, and I want you to be glad to help us up also.

Context: The world cannot utterly ignore men who lay down their lives for any cause.

Legislative Assembly, February 9, 1865
Context: The two greatest things that all men aim at in any free government are liberty and permanency. We have had liberty enough - too much perhaps in some respects - but at all events, liberty to our hearts content.

Remarks on Annual Elections (1775)

Context: The new tinge to modern minds is a vehement and passionate interest in the relation of general principles to irreducible and stubborn facts. All the world over and at all times there have been practical men, absorbed in 'irreducible and stubborn facts'; all the world over and at all times there have been men of philosophic temperament, who have been absorbed in the weaving of general principles. It is this union of passionate interest in the detailed facts with equal devotion to abstract generalisation which forms the novelty of our present society.
