I. Bernard Cohen Quotes

I. Bernard Cohen was the Victor S. Thomas Professor of the history of science at Harvard University and the author of many books on the history of science and, in particular, Isaac Newton.

Cohen was the first American to receive a PhD in history of science, was a Harvard undergraduate and then a PhD student and protégé of George Sarton who was the founder of Isis and the History of Science Society. Cohen taught at Harvard from 1942 until his death, and his tenure was marked by the development of Harvard's program in the history of science. He went on to succeed Sarton as editor of Isis and, later, president of the Society ; he was also a president of the International Union of the History and Philosophy of Science.

Cohen was an internationally recognized Newton scholar; his interests were encyclopedic, ranging from science and public policy to the history of computers, with several decades as a special consultant for history of computing with IBM. Among his hundreds of publications were such major books as Franklin and Newton , The Birth of a New Physics , The Newtonian Revolution , Revolution in Science , Science and the Founding Fathers , Howard Aiken: Portrait of a Computer Pioneer , and his last book, The Triumph of Numbers , not to mention two jointly authored contributions, the variorum edition and new English translation of Newton's Principia.

Cohen's April 1955 interview with Albert Einstein was the last Einstein gave before his death, in that same month. It was published that July in Scientific American, which also published Cohen's 1984 essay on Florence Nightingale.

In 1974 he was awarded the Sarton Medal by the History of Science Society. Many consider Cohen's most important work to be his 1999 translation, with the late Anne Whitman, of Newton's Principia. This 974-page work took Cohen over 15 years to fully translate.

Among Cohen's students were the Islamic philosopher Seyyed Hosein Nasr, Tufts University professor George E. Smith, Bucknell University professor Martha Verbrugge, Allen G. Debus and Jeremy Bernstein.

Famous I. Bernard Cohen Quotes

“The pioneering practitioners of the new science knew that they were producing a new kind of knowledge and so they declared this newness in the titles of their books and articles. Thus we have Galileo's Two New Sciences, Boyle's New Experiments, Kepler's New Astronomy, and Tartaglia's New Science. When Ben Jonson presented a masque entitled "News from the New World," his new world was not the newly found continent of North America, but the new world of science, the world revealed by the telescope of Galileo.”

The Triumph of Numbers: How Counting Shaped Modern Life (2005)

“The seventeenth century witnessed the birth of modern science as we know it today. The science was something new, based on a direct confrontation of nature by experiment and observation. But there was another feature of the new science—a dependence on numbers, on real numbers of actual experience.
…The ancients knew a few numerical laws… But prior to the Scientific Revolution, the goal of science (or the study of nature) was not to seek laws of nature expressed in terms of numbers or number relations. …the new science …not only found laws based on numbers but they were also willing to express these laws in terms of higher powers of numbers—squares and cubes.”

The Triumph of Numbers: How Counting Shaped Modern Life (2005)

“By contrast, Galileo, the other legendary scientific figure of the era, not only published the most compelling critique of Aristotelian scholasticism in his Dialogues on the Two Chief World Systems, but in the process turned the issue of the epistemic authority of theology versus the epistemic authority of empirical science into a hallmark of modern times. Although Newton clearly sympathized with Galileo, he wrote virtually nothing critical of the Aristotelian tradition in philosophy, and the immense effort he devoted to theology was aimed not at challenging its epistemic authority, but largely at putting it on a firmer footing. Newton made no direct contributions to philosophy of a similar magnitude. Indeed, from his extant writings alone Newton has more claim to being a major theologian than a major philosopher.”

“Of the many references to Newton in 18th-century electrical writings only a small number were to the Principia, the greater part by far were to the Opticks. This was true not alone of the electrical writings but also in other fields of experimental enquiry…. [The Opticks] would allow the reader to roam, with great Newton as his guide, through the major unresolved problems of science and even the relation of the whole world of nature to Him who had created it…. in the Opticks Newton did not adopt the motto… —Hypotheses non fingo; I frame no hypotheses—but, so to speak, let himself go, allowing his imagination full reign and by far exceeding the bounds of experimental evidence.”

I. Bernard Cohen, Preface to Opticks by Sir Isaac Newton (1952)

“Galileo had the experience of beholding the heavens as they actually are for perhaps the first time, and wherever he looked he found evidence to support the Copernican system against the Ptolemaic, or at least weaken the authority of the ancients. This shattering experience—of observing the depths of the universe, of being the first mortal to know what the heavens are actually like—made so deep a an impression… that it is only by considering the events of 1609… that one can understand the subsequent direction of his life.”

The Birth of a New Physics (1959)

“Isaac Newton deserves to be included in a series of companions to major philosophers even though he was not a philosopher in the sense in which Descartes, Locke, and Kant were philosophers. That is, Newton made no direct contributions to epistemology or metaphysics that would warrant his inclusion in the standard list of major philosophers of the seventeenth and eighteenth centuries – Descartes, Spinoza, Locke, Leibniz, Berkeley, Hume, and Kant – or even in a list of other significant philosophers of the era – Bacon, Hobbes, Arnauld, Malebranche, Wolff, and Reid. The contributions to knowledge that made Newton a dominant figure of the last millennium were to science, not to philosophy.”

“His conflict with the Catholic Church arose because deep in his heart Galileo was a believer. There was for him no path of compromise, no way to have separate secular and theological cosmologies. If the Copernican system was true as he believed, what else could Galileo do but fight with every weapon he had in his arsenal… to make his Church accept a new system of the universe. …In the contrast between Galileo's heroic stand when he tried to reform the cosmological basis of orthodox theology and his humbled, kneeling surrender when he disavowed his Copernicanism, we may sense the tremendous forces attendant on the birth of modern science.”

The Birth of a New Physics (1959)

“Opticks was out of harmony with the ideas of 19th-century physics. …an exposition of the "wrong" (i. e., corpuscular) theory of light,—even though it also contained many of the basic principles of the "correct" (i. e., wave) theory. Not only had Newton erred in his choice… but also he apparently had found no insuperable difficulty in simultaneously embracing features of two opposing theories. …by adopting a combination of the two theories at once, he had violated one of the major canons of 19th-century physics… Today our point of view is influenced by the theory of photons and matter waves, or the… complementarity of Niels Bohr; and we may read with a new interest Newtons ideas on the interaction of light and matter or his explanation of the corpuscular and undulatory aspects of light.”
