Page 545 - I stand and look at them long and long. They do not sweat and whine about their condition, They do not lie awake in the dark and weep for their sins They do not make me sick discussing their duty to God, Not one is dissatisfied, not one is demented with the mania of owning things, Not one kneels to another, nor to his kind that lived thousands of years ago, Not one is respectable or unhappy over the whole earth.
Page 383 - ... the School of Hygiene and Public Health of the Johns Hopkins University...
Page 559 - Till a voice, as bad as Conscience, rang interminable changes On one everlasting Whisper day and night repeated — so: "Something hidden. Go and find it. Go and look behind the Ranges — "Something lost behind the Ranges. Lost and waiting for you. Go!
Page 551 - But, finally, perfection, - as culture from a thorough disinterested study of human nature and human experience learns to conceive it, - is a harmonious expansion of all the powers which make the beauty and worth of human nature, and is not consistent with the over-development of any one power at the expense of the rest.
Page 289 - ... but a well-drawn part of a great chart, in which all physical science will be represented with every property of matter shown in dynamical relation to the whole. The prospect we now have of an early completion of this chart is based on the assumption of atoms. But there can be no permanent satisfaction to the mind in explaining heat, light, elasticity, diffusion, electricity and magnetism, in gases, liquids and solids, and describing precisely the relations of these different states of matter...
Page 290 - It is conceivable that the various kinds of matter, now recognized as different elementary substances, may possess one and the same ultimate or atomic molecule existing in different conditions of movement.
Page 555 - And many races of living things must then have died out and been unable to beget and continue their breed. For in the case of all things which you see breathing the breath of life, either craft or courage or else speed has from the beginning of its existence protected and preserved each particular race.
Page 451 - C, standing on the floor, both appear to be electrized; for he, having only the middle quantity of electrical fire, receives a spark upon approaching B, who has an over quantity ; but gives one to A , who has an under quantity. If A and B approach to touch each other, the spark is stronger, because the difference between them is greater. After such touch there is no spark between either of them and C, because the electrical fire in all is reduced to the original equality.
Page 216 - As I watch the American nation speeding gaily, with invincible optimism, down the road to destruction, I seem to be contemplating the greatest tragedy in the history of mankind.
Page 289 - But there can be no permanent satisfaction to the mind in explaining heat, light, elasticity, diffusion, electricity and magnetism, in gases, liquids, and solids, and describing precisely the relations of these different states of matter to one another by statistics of great numbers of atoms, when the properties of the atom itself are simply assumed. When the theory, of which we have the first instalment in Clausius and Maxwell's work, is complete, we arc but brought face to face with a superlatively...
