Whether or not he crossed those mice, the persistence of the story illustrates something broader about how scientific reputations are constructed and maintained.

This paper argues that in his time, Jean-Jacques Rousseau (1712-1778) described a similar phenomenon with similar consequences, explaining its origin and importance in a nuanced manner that is able to bring new insights to the current theoretical frameworks on human-nature connection. In this paper, an interpretation of Rousseau's philosophy with a systems approach is presented. Furthermore, by integrating it with temporary philosophy of systems biology and other relevant underpinnings, a framework for nature connectedness called the life-sustenance hypothesis is advanced, suggesting that all organisms are guided by two fundamental, parallel orientations: A self-sustaining orientation for self-preservative purposes and a life-sustaining orientation for sustaining surrounding life. Rousseau did not speak in these terms, but referred to different 'manners-of-being', the dynamics of which can be described with his central terms, amour-de-soi, amour-propre, and pitié. He suggested that the modern, individualistic lifestyle has introduced an excessive imbalance in these manners-of-beings, with harmful consequences on our well-being and the way we treat other beings. One possible solution Rousseau explored to resolve this imbalance-along with the political, educational, and domestic ones-was restoring personal inner peace, 'harmony with Nature'. The experience of harmony, I suggest, greatly resembles the immersive psychological nature connectedness depicted by contemporary research. Rousseau's system of thought is able to bring clarity into why we experience nature connectedness, and why it affects us the way it does.</p>","PeriodicalId":56308,"journal":{"name":"History and Philosophy of the Life Sciences","volume":"48 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13550017/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148908220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here I reconstruct the book with a particular focus on the cognition of organisms and read it in systematic relation to Kant, whose analysis of teleological judgment provides the clearest foil for Steiner's project. The guiding question is under what epistemic conditions living beings can become objects of genuine knowledge rather than merely regulative judgment. I reconstruct the argument in five steps: (1) pure experience as a structureless manifold; (2) thinking as a self-transparent and law-governed activity within experience; (3) cognition as the reunification of perception and concept under empirical constraint; (4) the contrast between inorganic and organic cognition; and (5) the claim that organisms can be understood through Goethe's concept of Typus, a developing method, and an intuitive power of judgment (anschauende Urteilskraft). Steiner's reconstruction of Goethe thus yields a position that transforms Kant's view of teleological judgment as merely regulative. A concluding section considers the relevance of this argument for current debates on organism-centred theoretical biology and the relation between subject and object in biological cognition.

Although early twentieth-century monogenic versions of hereditarianism-suggesting specific genes for traits like feeble-mindedness, nomadism, and pauperism-may now seem outdated, similar reasoning persisted into the early twenty-first century through candidate gene studies. With the advent of high-resolution genomic association studies, the understanding of complex traits has shifted toward a massively polygenic architecture, moving away from the \"gene for X\" paradigm. Nevertheless, the aspiration to identify purely genetic causes persists, and a more nuanced form of hereditarian theory continues to exist. This paper explores the evolution of hereditarianism in its various forms, examining its connections to racism and anti-egalitarian politics. In a sense, this work is an extension of the twentieth century critique of hereditarianism, in line with key figures like Richard Lewontin and Stephen Jay Gould. The paper begins with early twentieth-century eugenics and the hereditarian approach to IQ in the United States, progresses to modern scientific racism, and concludes with an evaluation of causal claims in contemporary social science genomics.

This paper advances a twofold argument. First, I contend that overreliance on model organisms constrains the generation of novel hypotheses and narrows the conceptual landscape of biological inquiry. Using epigenetic inheritance as a case study, I show how this focus has systematically marginalized forms of inheritance that depart from conventional assumptions (i.e., germline/material overlap and transgenerational stability). Here, I concentrate on external intergenerational epigenetic inheritance. Second, I argue that merely vindicating the use of experimental model organisms is insufficient without examining the philosophical assumptions that structure their epistemic function. Specifically, I demonstrate that the representationalist conception-models as surrogates for target systems-permeates the conceptualization of experimental model organisms through the idea of representational function, thereby reinforcing framed trajectory-dependent inquiry. This representationalist conceptualization undermines the capacity of experimental model organisms to support framing exploratory inquiry oriented to test conceptually disruptive ideas, such as external intergenerational epigenetic inheritance. To overcome this limitation, I develop a Pragmatist-Artifactualist framework that reconceptualizes the epistemic role of experimental model organisms and restores their potential to expand the boundaries of biological understanding.</p>","PeriodicalId":56308,"journal":{"name":"History and Philosophy of the Life Sciences","volume":"48 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13391654/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148563881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I start with a brief explanation of the term \"uniformitarianism\" and the identification of the fundamental hypotheses of Lyell's theory. Moving forward, I explore his idea of the balance of nature and show that Lyell believes that natural equilibrium represents a state of stability in inorganic and organic nature. As I show, the stability of inorganic nature is achieved through the alternate activity of natural - aqueous and igneous - forces, while the balance of organic nature is established via two processes: migrations of species and struggle for survival. However, the inorganic and organic natures are connected by a unilateral causal relation which enables the first to cause changes within the second. That being the case, the activity of inorganic forces can disturb the balance of organic nature and trigger modifications in the structure of organisms, leading to their evolution. Yet equilibrium can be restored through the interventions of the \"Author of nature\", who, as the instrument of evolution, equips every organism with useful variations necessary for their survival. Since organic nature represents an essential part of the natural system, the \"Author of nature\", through his actions, creates and preserves the balance of the whole nature. Thus, it appears that Lyell opts for a specific version of preformationism and that his uniformitarianistic worldview presupposes a significant regulative role for the omnipotent, omnipresent, and omniscient intelligent being.</p>","PeriodicalId":56308,"journal":{"name":"History and Philosophy of the Life Sciences","volume":"48 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148407074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tracing sentience's evolution from biological beginnings was the modest naturalistic proposal from pragmatist John Dewey. Curiously, his endorsement in his 1925 Experience and Nature of affective sentience across the animal world has gone almost entirely unnoticed by philosophy, psychology, and animal research. However, those disciplines may be converging on minimum expectations for sentient learning and behavior that Dewey had already proposed and defended. For Dewey, identifying and explaining cognitive conduct cannot be about outer behavioral adjustments or inner physiological operations taken separately - their organized coordination within environing conditions is the minimum situation for scientific investigations. An organism is perpetually engaging its environs (what it can sense) through enactions (what it can do) from energizations (what it can power) activated from its sensings-doings, in order to sustain itself as an organized entity. Hard dilemmas about demoting feeling to impotence or banishing experience from nature dissolve when vitality's own qualities are empirically respected.

Beginning with Pavlov's observation that dogs exposed to irresolvable conflict developed persistent behavioural and autonomic disturbances, the paradigm expanded through mid-century work by Liddell, Gantt, and Masserman, who introduced new species, longitudinal designs, and ecologically grounded conditions revealing dysregulation as a multilevel, temporally extended phenomenon. In this tradition, behaviour was not construed as mechanistic output but as an autonomous level of organisation whose structured patterns, i.e., variability, context-sensitivity, stability, and breakdown, made internal regulatory dynamics experimentally accessible in ways physiology alone could not. Hybrid methodologies integrating laboratory control with naturalistic observation showed that pathological breakdown provides access to organisational features obscured during normal function. By mid-century, however, this behaviourally rich framework was displaced by reductionist approaches based on standardised assays and physiological endpoints. Recent historiography documents this shift as an epistemological transformation in which behaviour was redefined from interface to index, from organised system to dependent variable. These tensions persist in contemporary neuroscience and translational research, where behaviour is routinely subordinated to mechanism despite gaps between circuit-level manipulation and behavioural explanation. This historical analysis supports the claim that mechanistic approaches which bypass behaviour incur explanatory loss, eliminating the domain in which neurophysiological processes acquire functional meaning. Progress in understanding psychopathology requires restoring behaviour to ontological and epistemological centrality as the irreducible interface through which adaptive and pathological regulation become scientifically accessible.</p>","PeriodicalId":56308,"journal":{"name":"History and Philosophy of the Life Sciences","volume":"48 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13346283/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148407070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"哲学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
