Famous quotes containing the words early, modern and/or period:
“I doubt that I would have taken so many leaps in my own writing or been as clear about my feminist and political commitments if I had not been anointed as early as I was. Some major form of recognition seems to have to mark a womans career for her to be able to go out on a limb without having her credentials questioned.”
—Ruth Behar (b. 1956)
“These modern ingenious sciences and arts do not affect me as those more venerable arts of hunting and fishing, and even of husbandry in its primitive and simple form; as ancient and honorable trades as the sun and moon and winds pursue, coeval with the faculties of man, and invented when these were invented. We do not know their John Gutenberg, or Richard Arkwright, though the poets would fain make them to have been gradually learned and taught.”
—Henry David Thoreau (18171862)
“After all, the practical reason why, when the power is once in the hands of the people, a majority are permitted, and for a long period continue, to rule is not because they are most likely to be in the right, nor because this seems fairest to the minority, but because they are physically the strongest. But a government in which the majority rule in all cases cannot be based on justice, even as far as men understand it.”
—Henry David Thoreau (18171862)
