Is there science before the Scientific Revolution?

If historians of science were to investigate past practices and beliefs only insofar as those practices and beliefs resemble modern science, the result would be serious distortion. (David C. Lindberg, The Beginnings of Western Science: The European Scientific Tradition in Philosophical, Religious, and Institutional Context, Prehistory to A.D. 1450, 2)

… they were operating within quite a different linguistic and conceptual world and with different purposes; and it is in the light of these that their achievements must be judged. (p. 9)

The second candidate for early modern revolutionary status is methodological—the invention and practice of the “experimental method” (according to the defenders of this thesis) by such sixteenth- and seventeenth-century scientists as Galileo, William Gilbert, Robert Boyle, and many others. According to defenders of this theory, the sterile scholastic debates and syllogistic demonstrations of ancient and medieval natural philosophy came to an end, replaced by experimental science, with its firsthand observation and manipulation under controlled conditions. (p. 362)

For present purposes, I am inclined to define it [the word "experiment" in experimental method" -DHC] narrowly, by what I take to be its primary epistemological function: an attempt to confirm or disconfirm a theoretical claim about the nature or behavior of the material world by an observation (under controlled conditions if necessary) made for that purpose, or the gathering of data against which future anticipated theoretical claims may be tested. (p. 362)

Experimentation continued through the later Middle Ages, wherever it met a scientific need. (p. 363)

… what credit is left for Francis Bacon (1561-1626) popularly celebrated as the founder (or a founder) of experimental science? … what he and the Baconian tradition of the seventeenth century gave us was not a new method of experiment, but a new rhetoric of experiment coupled with full exploitation of the possibilities of experiment in programs of scientific investigation. (p. 364)

Where, then can we locate this elusive revolution of sixteenth- and seventeenth-century science? I believe that Alexandre Koyré, who, in the 1950s and 1960s, disputed Combrie’s focus on experimental science as the revolutionary agent, has put his finder on the right place. The underlying source of revolutionary novelty in the sixteenth and seventeenth centuries, he argued, was metaphysical and cosmological rather than methodological. (p. 364)

Historian of science David Lindberg has written a book showing the intellectual foundations of modern Western science. In its elucidation of intellectual history, I find it compelling. However, Lindberg has seemingly asserted that ancient science is indeed "ancient SCIENCE." My question to that is: Can we actually called what we see prior to the Scientific Revolution "science"?

The question posed here is not to claim that there is no rich intellectual foundations for science prior to the Scientific Revolution. But for science to be "science," it must be distinct from anything that is not science, otherwise the word "science" has lost its meaning. This to me is my main objection to the whole idea of "ancient" or "medieval" science. Lindberg has held up Alexandre Koyré's thesis that the Scientific Revolution was "metaphysical and cosmological rather than methodological" (p. 364). From a philosophical perspective, that seems correct. But I think such is a partial picture, for a shift in metaphysical and cosmological perspective would surely affect one's methodology.

When one does scientific experiments today, one does not appeal to the divine or to spiritual forces as part of one's explanation for why things happen the way they do. The reason is that modern science is committed to what is called "methodological naturalism." That is indeed a philosophical commitment, yet it is necessary for modern science to be "science" as opposed to "philosophy" or "religion." Should science be committed to methodological naturalism? Well, if science is not committed to methodological naturalism, then where is the boundary between "science" and "philosophy," or "science" and "religion"? This is why I find Lindberg's definition of "experimental" in explaining one reason why there is a scientific revolution deficient. Judging by Lindberg's definition of "experimental," certain aspects of philosophy (e.g. that there is a God) and religion (e.g. the resurrection of Christ) can be termed "science," but we do not normally called these "science," do we?

It is because of the necessity of defining our terms properly that I think Lindberg's assertion of continuity between "ancient science" and "modern science" problematic. Rather, it is better to assert that there is a continuity between ancient natural philosophy and modern science. For "science" to be "science," there must be a commitment to methodological naturalism. That being said, I will assert that this is a limitation on science, for anything that is outside the realm of nature can still be true but it is outside science's purview. Thus, I will assert, contra Lindberg, that there was indeed a real scientific revolution that is more than just a shift in rhetoric (that marked the beginnings of modern science). I will further claim that the emergence of modern science does not imply the de-legitimization of anything that is non-science as disciplines that do not convey truth, since an a priori commitment to methodological naturalism precludes science from discovering truth outside of naturalistic events.
