Author Max Black argues that language should conform to the discovered regularities of experience it is radically mistaken to assume that the conception of language is a mirror of reality.

Robert John Ackermann deals decisively with the problem of relativism that has plagued post-empiricist philosophy of science. Recognizing that theory and data are mediated by data domains (bordered data sets produced by scientific instruments), he argues that the use of instruments breaks the dependency of observation on theory and thus creates a reasoned basis for scientific objectivity. Originally published in 1985. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist (...) of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Recently a number of philosophers have maintained that the meanings of terms in a scientific language are “theory-laden” or determined by the theory in which they occur, and thus that if the same term occurs in different theories, it will take on different meanings in the different theories; so the theories are incommensurable. An often-stated corollary to this doctrine is the claim that possessors of different theories cannot express or possess the same facts since they attach different meanings to the (...) terms used to give expression to the facts. Various attacks against this extreme doctrine on the relativity of facts have been mounted. Some of them consist in showing defective the argument advanced in support of this doctrine; but such criticisms at best show that the defenses offered for the doctrine are defective, not that the doctrine itself is defective.

Through a study of a sophisticated contemporary scientific experiment, it is shown how and why use of the term 'observation' in reference to that experiment departs from ordinary and philosophical usages which associate observation epistemically with perception. The role of "background information" is examined, and general conclusions are arrived at regarding the use of descriptive language in and in talking about science. These conclusions bring out the reasoning by which science builds on what it has learned, and, further, how that (...) process of building consists not only in adding to our substantive knowledge, but also in increasing our ability to learn about nature, by extending our ability to observe it in new ways. The argument of this paper is thus a step toward understanding how it is that all our knowledge of nature rests on observation. (shrink)

Philosophers have traditionally decried vagueness as an unmitigated evil, and natural scientists have consistently agreed with them. Nevertheless, as I hope to show, the vagueness of scientific terms has some important advantages for the theories in which these terms figure. In so arguing I do not mean to put the best face on some unpleasant facts or to make a virtue out of a necessity. I shall begin, however, by arguing that on some contemporary accounts of scientific language the vagueness (...) of many scientific terms is unavoidable; if it is unavoidable then lamenting it is futile, and justifying it is idle. I shall go on to argue that, independent of these accounts, the advantages of exactness attained can sometimes be substantially outweighed by the disadvantages of vagueness foregone. (shrink)

Because of the many criticisms of the notion of a theory independent observation language, it is useful to look at a few actual examples of scientific data to see what theories might be implicit and in what way. There are several possibilities. The theories could be previously accepted, under active investigation, or of a kind that has never been systematically examined. The present study explores these possibilities in the data of several scientific journal articles. The conclusion is that theories and (...) regularities of all three kinds can be found as antecedent conditions of data statements. Any descriptive account of scientific inference must find room for such presuppositions. (shrink)

I outline a pragmatic view of scientists' use of observation which draws attention to non-discursive, instrumental and social contexts of observation, in order to explain scientists' agreement about the appearance and significance of new phenomena. I argue that: observation is embedded in a network of activities, techniques, and interests; that experimentalists make construals of new phenomena which enable them communicate exploratory techniques and their outcomes, and that empirical enquiry consists of communicative, exploratory and predictive strategies whose interdependence ensures that, notwithstanding (...) the constructedness of representations and the empirical underdetermination of theories, observations contain information about the natural world.
