Taking the History of Science Really Seriously

by Scott A. Kleiner

The scientific revolution is a many-faceted realization of Kuhn's phylogenic tree (1962), whose trunk is ancient astronomy with ramifications into terrestrial physics (Galileo, Descartes. Huygens, Newton) and biology and medicine (Aristotle, Galen, Vesalius, Harvey, Descartes, Steno, Linnaeus, Darwin, Fisher,Morgan, Mayr, Rapp). 'Revolutions' of the sort documented in Kuhn's Structure (1962) are pervasive in the history of science, both physical and biological. Some of these are analyzed in this book , but continuity within a tradtion is sought. As Kuhn argues in The Copernican Revolution (1959), scientific change is gradual with overlapping concepts and ideals, so discovery can be the rational pursuit of an ideal recognized as yet unfulflled.
This book is intended to offer a historical, conceptual and methodological analysis of selected iconic shifts (revolutions) in scientific belief and practice. Part I is a reexamination of The Copernican Revolution in the light of philosophical thinking about the history of science that has emerged in the last 60 years since its publication in 1959 (Kuhn I). The philosophy and historiography drawn from Part I is then sought and compared with that evident in the history of evolutionary inquiries (Part II) and genetics (Part III). Since turning my focus to the Philosophy of Biology in the early 1970's, I have sought studies in its history with the objective of articulating a theory of change and discovery with the guidance of epistemic values realized in inquiries (questioning strategies) in the physical sciences (Kleiner, 1968, 1970). Particularly evident in the three disciplines here studied are the trade-offs between those willing to sacrifice realism (ontic comprehensiveness) for mathematical fruitfulness (instrumentalism). I was surprised to learn from Rosenberg's Instrumental Biology that there was instrumentalism in biology, because wasn't it obvious that Darwinian histories (Kitcher, 1984) had to be fully realistic to be causally efficacious? in explaining phylogeny? But, of course, R.A. Fisher's fruitful program articulated in articles (1915-1921) and a book in 1930 was instrumental biology. As with Galileo, Kepler and Newton, the pursuit of the goal of enhancing the realism of mathematical models was a driver of discovery as the Copernican Revolution unfolded (Kleiner, 197?), but also as the Darwinian-Mendelian revolutions unfolded. I thus advocate a heuristic and qualified realism, not the unrealizable 'literal' realism brought up in recent philosophical debates (Laudan, 1986) Newton settles for an ontology that gives progressively epistemically accurate models only up to a point, the point at which empirical resolution is technically limited and, as we now know, causal determinativeness declines into chaos (Randall, 2014). Mendelism and evolutionary theory has a similar escalation of realism and indeterminism from linkage, adding chromosomes to the ontology (late 19th century cytology), to karyotypes and sub-karyotypes, to subpopulations emerging within genetic populations, to cells, developing biological individuals, reproductive and symbiotic groups, genes, their sequences, enzymes and theirs, regulators, enhancers and repressors, major transitions (Michod, 1999), and comparative developmental studies (Raff, 1996). Mendelian populations were initially studied with single-locus models and were, like the Laplacian Ideal, fully deterministic in their etiology (at least in Fisher's ideal infinite populations). Introducing linkage in computer models of the Mendelian reproductive cycle gives rise to chaos, where small variations of allelic fitnesses produce diverging evolutionary trajectories. The same outcome occurs with the proliferation of small Mendelian isolates, where sampling error generates sampling error and disparity among these isolates.
About the author
I was born in Cincinnati OH in 1938. I was educated at Williams College (B.A. Physics, 1960), University of Chicago (M.A. 1961; Ph.D 1968). My employment was at Sweet Briar (Instructor 1965-1969), University of Georgia (Assistant Professor 1969-1977, Associate Professor 1977 and Professor and Professor Emeritus 19992, 20004 to the present). I studied the history of biology at Cambridge University UK (1973-4), discovery and inquiry at the University of Pittsburgh (1985-9) and Genetics at the University of Georgia (1992-3). i published a book on the logic of discovery in 1993. I am still pursuing scientific change and discovery in the physical and biological sciences.
