The main focus is on a recent hypothesis that attributes all responsibility for this error to Ptolemy’s adoption of the wrong value for the circumference of the Earth. This explanation has challenging implications for our understanding of ancient geography: it presupposes that before Ptolemy there had been a tradition of high-accuracy geodesy and cartography based on Eratosthenes’ measurement of the Earth. The essay argues that this hypothesis does not stand up to scrutiny. The story proves to be much more complex than can be accounted for by a single-factor explanation. A more careful analysis of the evidence allows us to assess the individual contribution to Ptolemy’s error made by each character in this story: Eratosthenes, Ptolemy, ancient surveyors, and others. As a result, a more balanced and well-founded assessment is offered: Ptolemy’s reputation is rehabilitated in part, and the delusion of high-accuracy ancient cartography is dispelled.</p>","PeriodicalId":14667,"journal":{"name":"Isis","volume":"107 4","pages":"687-706"},"PeriodicalIF":0.6,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1086/689763","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36218887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But the magnetical cosmology, as professed by those in the movement, differed from Gilbert’s philosophy in highly significant ways. Proponents never accepted Gilbert’s animistic account of magnets and seem tacitly to have accepted a belief in action at a distance that Gilbert himself rejected.

There is a general need for a concise overview of the rise of modern science, with a clear structure allowing for a rough division into periods. This essay proposes such a scheme, one that is both elementary and comprehensive. It focuses on four machines, which can be seen to have mediated between science and society during successive\u0000periods of time: the clock, the balance, the steam engine, and the computer. Following an extended developmental phase, each of these machines came to play a highly visible role in Western societies, both socially and economically. Each of these machines, moreover,\u0000was used as a powerful resource for the understanding of both inorganic and organic nature. More specifically, their metaphorical use helped to construe and refine some key concepts that would play a prominent role in such understanding. In each case the key concept would at some point be considered to represent the ultimate building block of reality. Finally, in a refined form, each of these machines would eventually make its entry\u0000in scientific research, thereby strengthening the ties between these machines and nature.</p>","PeriodicalId":14667,"journal":{"name":"Isis","volume":"107 4","pages":"762-76"},"PeriodicalIF":0.6,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1086/689764","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36219075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly important for this power is the\u0000diversity of the particular constructions that constitute mediators like “balances” or “engines.” Diversity of meaning and action gives them their cultural reach, from mechanical contrivance to natural process to political ideology. An interesting question remains about how many mediating machines will suffice for the big picture of modernity over four centuries. Statistics, for example, might be a crucial addition.
