“There never seems to be any difficulty in stretching the laws and the constitution to fit any kind of a political deal, but when it is proposed to make some concession to women they loom up like an unscalable wall.”
—Susan B. Anthony (1820–1906)
“The philosopher is in advance of his age even in the outward form of his life. He is not fed, sheltered, clothed, warmed, like his contemporaries. How can a man be a philosopher and not maintain his vital heat by better methods than other men?”
—Henry David Thoreau (1817–1862)
“Ktaadn ... is an Indian word signifying highest land,... very few, even among backwoodsmen and hunters, have ever climbed it, and it will be a long time before the tide of fashionable travel sets that way.”
—Henry David Thoreau (1817–1862)
