"The man of science deals with questions which commonly lie outside of the range of ordinary experience, which often have no immediately discernible relation to the affairs of everyday life, and which concentrate the mind upon apparent abstractions to an extraordinary degree." (Frank W Clarke, "The Man of Science in Practical Affairs", Appletons' Popular Science Monthly Vol. XLV, 1900)
"Scientific facts are of little value in themselves. Their significance is their bearing upon other facts, enabling us to generalize and so to discover principles, just as the accurate measurement of the position of a star may be without value in itself, but in relation to other similar measurement of other stars may become the means of discovering their proper motions. We refine our instruments; we render more trustworthy our means of observation we extend our range of experimental inquiry, and thus lay the foundation for the future work, with the full knowledge that, although our researches can not extend beyond certain limits, the field itself is, even within those limits, inexhaustible." (Elihu Thompson, "The Field of Experimental Research", 1901)
"It is a matter of primary importance in the cultivation of those sciences in which truth is discoverable by the human intellect that the investigator should be free, independent, unshackled in his movement; that he should be allowed and enabled to fix his mind intently, nay, exclusively, on his special object, without the risk of being distracted every other minute in the process and progress of his inquiry by charges of temerariousness, or by warnings against extravagance or scandal." (John H Newman, "The Idea of a University Defined and Illustrated", 1905)
"[...] the data with which any scientific inquiry has to do are trivialities in some other bearing than that one in which they are of account." (Thorstein Veblen, "The Place of Science in Modern Civilisation and Other Essays", 1906)
"Modern masters of science are much impressed with the need of beginning all inquiry with a fact. The ancient masters of religion were quite equally impressed with that necessity. They began with the fact of sin - a fact as practical as potatoes. Whether or not man could be washed in miraculous waters, there was no doubt at any rate that he wanted washing." (Gilbert K Chesterton, "Orthodoxy", 1908)
"The things to be investigated are either true or false. If false, pertinacious inquiry will reveal their falsity. If true, they are profoundly important. For there are no half-truths in Nature; every smallest departure has portentous consequences; our eyes must open slowly, or we should be overwhelmed." (Oliver J Lodge, "Raymond, or Life and Death", 1916)
"Scientific principles and laws do not lie on the surface of nature. They are hidden, and must be wrested from nature by an active and elaborate technique of inquiry." (John Dewey, "Reconstruction in Philosophy", 1920)
"The first distinguishing characteristic of thinking is facing the facts - inquiry, minute and extensive scrutinizing, observation." (John Dewey, "Reconstruction in Philosophy", 1920)
"The fundamental concepts of each science, the instruments with which it pro pounds its questions and formulates its solutions, are regarded no longer as passive images of something but as symbols created by the intellect itself." (Ernst Cassirer, "The Philosophy of Symbolic Forms", 1923)
