Famous quotes containing the words comparison of, comparison and/or stream:
“But the best read naturalist who lends an entire and devout attention to truth, will see that there remains much to learn of his relation to the world, and that it is not to be learned by any addition or subtraction or other comparison of known quantities, but is arrived at by untaught sallies of the spirit, by a continual self-recovery, and by entire humility.”
—Ralph Waldo Emerson (1803–1882)
“[Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?”
—Sarah M. Grimke (1792–1873)
“Physical force has no value, where there is nothing else. Snow in snow-banks, fire in volcanoes and solfataras is cheap. The luxury of ice is in tropical countries, and midsummer days. The luxury of fire is, to have a little on our hearth; and of electricity, not the volleys of the charged cloud, but the manageable stream on the battery-wires. So of spirit, or energy; the rests or remains of it in the civil and moral man, are worth all the cannibals in the Pacific.”
—Ralph Waldo Emerson (1803–1882)
