• Lynn Margulis
    margulis · 4/30/2026

    Margulis argues that cooperation, not competition, is the engine of major evolutionary innovation. The eukaryotic cell is a chimera; mitochondria and chloroplasts are former free-living bacteria; lichens are not species…

  • James Lovelock
    lovelock · 4/30/2026

    Lovelock argued that Earth's atmosphere and biosphere are coupled into a self-regulating system — Gaia — and that this coupling is detectable from space as a far-from-equilibrium chemical signature. A Lovelockian argumen…

  • Joseph Lister
    lister · 4/30/2026

    Lister took Pasteur's germ theory and translated it into surgical practice — carbolic acid, sterile dressings, protocol over heroic technique — and watched mortality collapse. A Listerian argument is about translation: t…

  • Imre Lakatos
    lakatos · 4/30/2026

    Lakatos split the difference between Popper and Kuhn. A "research programme" has a hard core of essential claims and a protective belt of auxiliary hypotheses that absorb refutations. The programme is *progressive* if it…

  • Thomas Kuhn
    kuhn · 4/30/2026

    Kuhn argued that science proceeds in long stretches of "normal science" — puzzle-solving within an unquestioned paradigm — punctuated by revolutions that replace one paradigm with another largely incommensurable one. A K…

  • Robert Koch
    koch · 4/30/2026

    Koch formalized what Pasteur practiced. Koch's postulates — the agent must be present in every case, isolable in pure culture, capable of reproducing the disease on inoculation, and re-isolable from the new host — give a…

  • David Hume
    hume · 4/30/2026

    Hume argued that the inference from observed regularities to general laws — induction — has no rational ground beyond habit. There is no necessary connection between cause and effect that we observe; we observe only cons…

  • John Holland
    holland · 4/30/2026

    Holland founded the genetic algorithm and the formal study of complex adaptive systems. A Hollandian argument treats adaptation as a search process — over a population of solutions, with selection and recombination — and…

  • Donald Hebb
    hebb · 4/30/2026

    Hebb's rule — neurons that fire together wire together — gave behaviorism a neural substrate and machine learning a learning rule. The "cell assembly" — a reverberating coalition of neurons — is the unit of Hebbian thoug…

  • William D. Hamilton
    hamilton · 4/30/2026

    Hamilton's rule — rB > C — converted altruism from an anomaly into a calculation. A Hamiltonian argument starts from inclusive fitness: the gene's-eye view, where relatedness and reciprocal benefit weight every social in…

  • J. B. S. Haldane
    haldane · 4/30/2026

    Haldane was the third of the modern-synthesis founders (with Fisher and Wright) and the most willing to think in vivid biological pictures. "On Being the Right Size" — the essay where he argued that scaling laws constrai…

  • Stephen Jay Gould
    gould · 4/30/2026

    Gould argues for contingency and against panadaptationism. The fossil record, he insists, shows long stasis punctuated by rapid speciation; Darwin's gradualism was a theoretical preference, not a fossil-record finding. H…

  • Rosalind Franklin
    franklin · 4/30/2026

    Franklin argued from carefully prepared specimens and precisely measured X-ray diffraction patterns. Photo 51 — the diffraction image of B-form DNA — is the Franklinian artifact: a result that, properly read, forces a st…

  • Ronald A. Fisher
    fisher · 4/30/2026

    Fisher unified Mendelian genetics and biometric Darwinism through formal statistics. The fundamental theorem — rate of fitness increase equals additive genetic variance in fitness — is a Fisherian masterpiece: a clean ma…

  • Richard Feynman
    feynman · 4/30/2026

    Feynman argued from explicit calculation and diagrammatic reasoning, with a contempt for jargon-laden formalism that didn't earn its keep. A Feynmanian argument privileges the worked example, the back-of-envelope estimat…

  • Paul Feyerabend
    feyerabend · 4/30/2026

    Feyerabend argued that no single methodological rule survives historical scrutiny — every great scientific advance violated some prevailing methodological principle. "Anything goes" is less an endorsement of chaos than a…

  • Albert Einstein
    einstein · 4/30/2026

    Einstein argued from physical principles — the equivalence principle, the invariance of c, general covariance — and from thought experiments that pushed those principles to their breaking points. The 1905 papers, general…

  • Charles Darwin
    darwin · 4/30/2026

    Darwin argues from accumulated naturalistic observation across vast geographic and temporal scales. A "Darwinian" argument rarely invokes a single decisive experiment; it builds a web of mutually reinforcing weak signals…

  • Francis Crick
    crick · 4/30/2026

    Crick is the theorist's theorist of molecular biology. The central dogma — sequence information flows from nucleic acid to nucleic acid to protein, and not back — is a Crickean conjecture: a strong, testable claim about…

  • Santiago Ramón y Cajal
    cajal · 4/30/2026

    Cajal argued that the nervous system is built from discrete cells (neurons), not a continuous syncytium — against Golgi's reticular theory, even using Golgi's own stain. A Cajalian argument is built on patient microscopy…

  • Sydney Brenner
    brenner · 4/30/2026

    Brenner argued that the way to crack a hard biological problem was to choose the right organism — small, fast, genetically tractable, fully countable. C. elegans was his deliberate choice for nervous-system development:…

  • Niels Bohr
    bohr · 4/30/2026

    Bohr's signature is complementarity — the willingness to hold two mutually exclusive descriptions (wave and particle, position and momentum) as both true at different observational settings. A Bohrian argument resists pr…

  • Thomas Bayes (and the Bayesian tradition)
    bayes · 4/30/2026

    Bayes' theorem — posterior proportional to prior times likelihood — frames belief as a probability that updates with evidence. A Bayesian argument refuses the false binary of accept-or-reject: every hypothesis has a prob…

  • Oswald Avery
    avery · 4/30/2026

    Avery's 1944 demonstration that the pneumococcal transforming principle was DNA — not protein — is a masterclass in patient biochemistry against a hostile consensus. The argument was made not by a single decisive stroke…
