![]() ![]() The chapters on otherwise quite fascinating stories are marred by an insistence on claims that are not and ultimately cannot be fully supported. These grand statements undermine its more reasonable claims. And so it did: the ultimate victory of the infinitely small helped open the way to a new and dynamic science, to religious toleration, and to political freedoms on a scale unknown in human history.” (14) The statement that “the mathematical continuum is composed of distinct indivisibles” is innocent enough to us, but three and a half centuries ago it had the power to shake the foundations of the early modern world. ![]() The results of the fight were not everywhere the same, but the stakes were always just as high: the face of the modern world, then coming into being. On the one side were the advocates of intellectual freedom, scientific progress, and political reform: on the other, the champions of authority, universal and unchanging knowledge, and fixed political hierarchy. The lines in the struggle were clearly drawn. “From north to south, from England to Italy, the fight over the infinitely small raged across western Europe. The thesis of the book goes beyond developments in mathematics and makes a much larger claim: The triumph of Wallis and the mathematics of infinitesimals (“infinitely small” quantities in intuitive calculus) is argued to be central to the flourishing of mathematics and democracy in England. The second part concerns England in the course and aftermath of the English revolution and focuses on debates between Thomas Hobbes and John Wallis. The first part is devoted to showing that the Jesuit brotherhood hindered the development of the precursor of the calculus and ultimately thwarted the development of mathematics in Italy until, I presume, the Risorgimento (Italy’s 19th century unification). This is an idiosyncratic book driven by its two-part thesis. ![]() Infinitesimal: How a dangerous mathematical theory shaped the modern world, by UCLA professor Amir Alexander, is a history in two parts of certain mathematical ideas that emerged in 17th century Europe with a focus on Italy and England. If mathematics is not an unfolding of truths hidden in its logical structure, what propels it and can its progress be brought to a halt or accelerated? There can be no general answer to this question, but the study of particular developments in historical context can help us understand how and why certain ideas emerge at definite points in history at particular places.Įxamination of the historical record, and nuanced attempts to tease out the historical and social forces at play in the development of mathematics, are worthwhile. Thus all axiomatic systems are incomplete in the sense that the truth of all meaningful statements cannot be established. Gödel’s theorems proved that in any axiomatic system (sufficient for arithmetic), there are statements that can neither be proven nor disproven within that system. The project remained unfinished, not only due to the enormity of its own ambitions but irremediably with Kurt Gödel’s theorems from the 1930s showing the incompleteness of all logical systems. The view of mathematics as a closed axiomatic system was pursued to its utmost limits by Bertrand Russell and Alfred North Whitehead in the early part of the 20th century culminating in their Principia Mathematica, appearing in the 1910s. The abilities of individual mathematicians play a role, but these abilities are fashioned and nurtured (or not) in definite historical and social circumstances as well as subcultures, households and families. It is not a closed logical system, and its history is like the history of any discipline - far from the sequential unraveling of truths immanent in its logical structure, it is a narrative of contingent goals and programs, varying material resources, demands of governments and society, the serendipitous coming together of communities of mathematicians, and the psychology and personal circumstances of individual mathematicians. Yet mathematics is decidedly not like that. The pace of this history would then be a function of the abilities of the actors engaged in carrying out these logical steps. MATHEMATICS CONCEIVED AS a closed logical system, based on a set of axioms, may suggest that its history would be an account of the inevitable logical development of these axioms.
