Without encroaching upon grounds appertaining to the theologian and the philosopher, the domain of natural sciences is surely broad enough to satisfy the wildest ambition of its devotees. In other departments of human life and interest, true progress is rather an article of faith than a rational belief; but in science a retrograde movements is, from the nature of the case, almost impossible. Increasing knowledge brings with it increasing power, and great as are the triumphs of the present century, we may well believe that they are but a foretaste of what discovery and invention have yet in store for mankind. ... The work may be hard, and the discipline severe; but the interest never fails, and great is the privilege of achievement.

Address to the British Association in Montreal (1884)John Strutt
When a man sets out upon any course of inquiry, the object of his search may be either light or fruit — either knowledge for its own sake or knowledge for the sake of good things to which it leads. In various fields of study these two ideals play parts of varying importance. In the appeal made to our interest by nearly all the great modern sciences some stress is laid both upon the light-bearing and upon the fruit-bearing quality, but the proportions of the blend are different in different sciences. At one end of the scale stands the most general science of all, metaphysics, the science of reality. Of the student of that science it is, indeed, true that "he yet may bring some worthy thing for waiting souls to see"; but it must be light alone, it can hardly be fruit that he brings. Most nearly akin to the metaphysician is the student of the ultimate problems of physics. The corpuscular theory of matter is, hitherto, a bearer of light alone. Here, however, the other aspect is present in promise; for speculations about the structure of the atom may lead one day to the discovery of practical means for dissociating matter and for rendering available to human use the overwhelming resources of intra-atomic energy.
Arthur Cecil Pigou
The core of the belief in progress is that human values and goals converge in parallel with our increasing knowledge. The twentieth century shows the contrary. Human beings use the power of scientific knowledge to assert and defend the values and goals they already have. New technologies can be used to alleviate suffering and enhance freedom. They can, and will, also be used to wage war and strengthen tyranny. Science made possible the technologies that powered the industrial revolution. In the twentieth century, these technologies were used to implement state terror and genocide on an unprecedented scale. Ethics and politics do not advance in line with the growth of knowledge — not even in the long run.
John N. Gray
Cultural systems will be treated as extensions of the power to learn, store, and transmit information, and the evolution of culture as dependent upon the biological development of these abilities and the cultural developments that actualize them. Man's increasing mastery over the natural world, with its increments of available energy use, can be seen from this point of view as one consequence of his capacity to learn, invent, borrow, store, and transmit the necessary technological and political inventions for the changes of scale involved in increasing utilization of energy. Instead of focusing attention on discontinuities — the invention of tool-making tools, the invention of agriculture, the invention of writing, and the invention of invention as a conscious pursuit—this discussion will focus on the continuities involved and on the extent to which older forms of communication, energy use, and social organization also undergo transformation in the course of cultural evolution.
Margaret Mead
It is the man of science, eager to have his every opinion regenerated, his every idea rationalized, by drinking at the fountain of fact, and devoting all the energies of his life to the cult of truth, not as he understands it, but as he does not yet understand it, that ought properly to be called a philosopher. To an earlier age knowledge was power — merely that and nothing more; to us it is life and the summum bonum. Emancipation from the bonds of self, of one's own prepossessions, importunately sought at the hands of that rational power before which all must ultimately bow, — this is the characteristic that distinguishes all the great figures of nineteenth-century science from those of former periods.
Charles Sanders Peirce
The social scientist is in a difficult, if not impossible position. On the one hand there is the temptation to see all of society as one's autobiography writ large, surely not the path to general truth. On the other, there is the attempt to be general and objective by pretending that one knows nothing about the experience of being human, forcing the investigator to pretend that people usually know and tell the truth about important issues, when we all know from our lives how impossible that is. How, then, can there be a "social science"? The answer, surely, is to be less ambitious and stop trying to make sociology into a natural science although it is, indeed, the study of natural objects. There are some things in the world that we will never know and many that we will never know exactly. Each domain of phenomena has its characteristic grain of knowability. Biology is not physics, because organisms are such complex physical objects, and sociology is not biology because human societies are made by self-conscious organisms. By pretending to a kind of knowledge that it cannot achieve, social science can only engender the scorn of natural scientists and the cynicism of the humanists.
