This has created serious misconceptions about Semmelweis's reasoning and conclusions. The purpose of this article is to correct these misconceptions by presenting a detailed textual exegesis of Semmelweis's own account of how he came to his conclusions, and to answer fundamental questions about the differences between the present account of Semmelweis's work and those published in the philosophy of science literature, namely, whether methodological differences in how the respective accounts were constructed explain the differences, and which account philosophers should accept and on what basis.</div></div>","PeriodicalId":49467,"journal":{"name":"Studies in History and Philosophy of Science","volume":"119 ","pages":"Article 102233"},"PeriodicalIF":1.3,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149070411","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}

I will argue that this thought, central to the preference purification project in behavioural welfare economics, commits a fallacy. The standard theory requires agents to adopt precise preferences; but neither the theory nor a fuzzy agent’s initial attitudes may determine a particular way in which she ought to precisify them. So before actually having precisified her preferences, the welfare of fuzzy agents may remain indeterminate.

In this paper, we examine what Lewin meant by this opposition and how it fits into the disciplinary discourse of psychology and philosophy of science in the first half of the 20th century. We show that Lewin was one of the earliest figures to raise Galileo up to cult status as the pioneer of modern scientific thought: Lewin's invocation of Galileo predates that of Husserl and Koyré, who are often seen as the originators of the 20th-century image of Galileo. We also show that Lewin's opposition of ‘Galilean’ and ‘Aristotelian’ thought was a move in controversies of the time about the ‘crisis of psychology’, and that Lewin intended his opposition above all as an attack on his rival Karl Bühler (1879–1963).</div></div>","PeriodicalId":49467,"journal":{"name":"Studies in History and Philosophy of Science","volume":"117 ","pages":"Article 102130"},"PeriodicalIF":1.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147373389","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}

In demonstrative induction, inductive risk is confined to the premises, and the secureness of the conclusion depends on the secureness of those premises. I show that Newton's approach to chronology exemplifies two key restrictions on demonstrative induction: (i) premises must themselves be supported by demonstrative induction or by inductive generalizations, and (ii) inductive risk should be confined to premises drawn from domains of inquiry whose claims are better established, thereby “exporting” inductive risk to more certain domains. Drawing on Newton's use of sources from history, biology, social science, and astronomy, I analyze how he transformed data from these fields into evidence for his chronological scheme. The strategy of exporting inductive risk, I argue, reveals a common evidential pattern across his natural-philosophical, historical, and theological work, and sheds light on the deeper methodological unity that underlies his otherwise disparate intellectual pursuits.</div></div>","PeriodicalId":49467,"journal":{"name":"Studies in History and Philosophy of Science","volume":"117 ","pages":"Article 102154"},"PeriodicalIF":1.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148158804","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}

The feasibility of quantification is usually assessed by identifying similarities and differences to quantitative measurement in physics. We argue that the case studies used to exemplify physical measurement are not sufficiently representative to underwrite such assessments. We substantiate this thesis by reconstructing how seismologists quantified “earthquake size.” Seismology demonstrates that quantification can succeed under conditions that, on the one hand, differ from canonical case studies and, on the other, resemble those of the human sciences in relevant respects—seismologists study phenomena that are not amenable to significant experimental control and that cannot be isolated from complex background conditions. This allows us to refute an influential argument for the impossibility of human science quantification, which turns on the claim that experimental control is a necessary condition for quantification (Trendler, 2009). Finally, we draw constructive lessons for the human sciences from the method that seismologists Charles Richter and Beno Gutenberg used to quantify earthquake size. That method starts by introducing (approximate and circumscribed) “placeholder” scales, which can then be extended and revised to account for inevitable disturbing factors in the measurement process. We use this method to identify promising developments but also continued shortcomings in a noteworthy effort at quantification: the Lexile measure of reading comprehension.</div></div>","PeriodicalId":49467,"journal":{"name":"Studies in History and Philosophy of Science","volume":"117 ","pages":"Article 102132"},"PeriodicalIF":1.8,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147373386","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}

Yet, understanding these features more precisely is an open problem. In this paper, I focus on emergent novelty. In the contemporary debate, this feature has been steadily interpreted in causal terms, and this causal interpretation has often been developed in a power-based framework. Moreover, several authors who played important roles in reintroducing this interpretation in the contemporary debate traced it back to the so-called “British Emergentists”. This paper aims to show that this alleged inheritance should be carefully reassessed. On the one hand, at least some of the early emergentists (John Stuart Mill, Conwy Lloyd Morgan, and Samuel Alexander) did not attach tremendous importance to causal efficacy compared to other forms of emergent novelty that I suggest calling “qualitative”. On the other hand, while contemporary accounts of emergence are prevalently outlined within a non-Humean metaphysical framework in which talk of powers is pertinent, at least some of the early emergentists were prevalently Humean in relation to causality, and explicitly rejected talk of powers or causal properties. Moreover, both Alexander and Lloyd Morgan recognised at least another form of causal efficacy associated with what the former called “Nisus”. This paper suggests that acknowledging and recovering these pluralist views about novelty and causation, besides representing a more accurate reading of early emergentism, would allow for the formulation of better and more comprehensive models of emergence.</div></div>","PeriodicalId":49467,"journal":{"name":"Studies in History and Philosophy of Science","volume":"116 ","pages":"Article 102103"},"PeriodicalIF":1.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145950329","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}
