In olden times, men of science, and especially those who have done most to forward the growth of natural philosophy, did not despise manual work and handicraft. Galileo made his telescopes with his own hands. Newton learned in his boyhood the art of managing tools; he exercised his young mind in contriving most ingenious machines, and when he began his researches in optics he was able himself to grind the lenses for his instruments and himself to make the well known telescope which, for its time, was a fine piece of workmanship. Leibnitz was fond of inventing machines: windmills and carriages to be moved without horses preoccupied his mind as much as mathematical and philosophical speculations. Linnaeus became a botanist while helping his f... (From : Anarchy Archives.)
The Impulse to Power introduction to the book "Power" by Bertrand Russell . Between man and other animals there are various differences, some intellectual, some emotional. One of the chief emotional differences is that some human desires, unlike those of- animals, are essentially boundless and incapable of complete satisfaction. The boa constrictor, when he has had his meal, sleeps until appetite revives; if other animals do not do likewise, it is because their meals are less adequate or because they fear enemies. The activities of animals, with few exceptions, are inspired by the primary needs of survival and reproduction, and do not exceed what these needs make imperative. With men, the matter is...

The Century Magazine, July 1929, Vol. 118, No. 3, Pgs. 311-315 The Twilight Of Science Is The Universe Running Down Bertrand Russell It is a curious fact that just when the man in the street has begun to believe thoroughly in science, the man in the laboratory has begun to lose his faith. When I was young, no physicist entertained the slightest doubt that the laws of physics give us real information about the motions of bodies, and that the physical world does really consist of the sort of entities that appear in the physicist's equations. The philosophers, it is true, throw doubt upon this view, and have done so ever since the time of Berkeley; but since their criticism never attached itself to any point in the detailed procedure of scienc...

It was easy to foresee that the great revival of Natural Science which our generation has had the happiness to witness for thirty years, as also the new direction given to scientific literature by a phalanx of prominent men who dared to bring up the results of the most complicated scientific research in a shape accessible to the general reader, would necessarily bring about a like revival of Geography. This science, which takes up the laws discovered by its sister sciences, and shows their mutual action and consequences with regard to the surfaces of the globe, could not remain an outsider to the general scientific movement; and we see now an interest awakened in Geography which very much recalls the general interest taken in it by a procee...
