"I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me."
"The scientific observer of the realm of nature is in a sense naturally and inevitably disinterested. At least, nothing in the natural scene can arouse his bias. Furthermore, he stands completely outside of the natural so that his mind, whatever his limitations, approximates pure mind. The observer of the realm of history cannot be disinterested in the same way, for two reasons: first, he must look at history from some locus in history; secondly, he is to a certain degree engaged in its ideological conflicts."
"The whole of modern thought is steeped in science; it has made its way into the works of all our best poets, and even the mere manof letters, who affects to ignore and despise science, is unconsciously impregnated with her spirit, and indebted for his best products to her methods. I believe that the greatest intellectual revolution mankind has yet seen is now slowly taking place by her agency. She is teaching the world that the ultimate court of appeal is observation and experiment, and not authority; she is teaching it to estimate the value of evidence; she is creating a firm and living faith in the existence of immutable moral and physical laws, perfect obedience to which is the highest possible aim of a intelligent being."
"Mix salt and sand, and it shall puzzle the wisest of men, with his mere natural appliances, to separate all the grains of sand from all the grains of salt; but a shower of rain will effect the same object in ten minutes."
"Anyone who is practically acquainted with scientific work is aware that those who refuse to go beyond fact rarely get as far as fact; and anyone who has studied the history of science knows that almost every great step therein has been made by the "anticipation of Nature."
"The present war having so long cut off all communication with Great-Britain, we are not able to make a fair estimate of the stateof science in that country. The spirit in which she wages war is the only sample before our eyes, and that does not seem the legitimate offspring either of science or of civilization."
"The conflict between science and religion is in reality a misunderstanding of both. Scientific materialism has merely introduced anew hypostasis, and that is an intellectual sin. It has given another name to the supreme principle of reality and has assumed that this created a new thing and destroyed an old thing. Whether you call the principle of existence "God," "matter," "energy," or anything else you like, you have created nothing; you have merely changed a symbol. The materialist is a metaphysician malgré lui. Faith, on the other hand, tries to retain a primitive mental condition on merely sentimental grounds. It is unwilling to give up the primitive, childlike relationship to mind-created and hypostatized figures; it wants to go on enjoying the security and confidence of a world still presided over by powerful, responsible, and kindly parents."
"As in political revolutions, so in paradigm choice--there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists."
