- Disjointness
- In immunology, self-versus-non-self discrimination is a disjointness judgment over molecular markers, and autoimmunity is its failure.
This sourceFoundational immunological account of self/non-self discrimination as a disjointness judgment over molecular markers, with autoimmunity as the breakdown of that separation.

Burnet gives self/not-self discrimination by clonal elimination and treats autoimmunity as its breakdown, but rejects "self-markers" and never frames it as disjointness.
“Self- not-self recognition means simply that all those clones which would recognize (that is, produce antibody against) a self component have been eliminated in embryonic life.”

- Interpretation
- … a thermostat with a learned setpoint, or a seismic monitoring system reading subsurface motion into earthquake-or-not classifications — readings whose framework, in the biological case, was first articulated as a selection-trained discriminator by Burnet (1959) in the clonal-selection theory of antibody response.
This sourceFoundational formulation of clonal selection: antigen exposure selects from a pre-existing diverse lymphocyte repertoire, and selected clones persist as immune memory. Establishes adaptive immunity as a substrate-furthest case of the learning skeleton — modifiable repertoire, experiential input, selection-and-mutation update, lifelong durability — entirely without cognition or instruction.

- Learning
- No cognition, no language, no consciousness — and yet every role in the structural pattern is cleanly present, as Burnet (1959) established in formulating the clonal selection theory that underwrites adaptive immune memory.

Burnet's Flexner lectures set out the clonal selection hypothesis and the long persistence of immunological memory, but not the learning-skeleton framing or the no-cognition point.
“This is the crux of the clonal selection hypothesis. It assumes that in the animal there exist clones of mesenchymal cells, each carrying immunologically reactive sites”

- Natural Selection
- In immunology the same engine runs within a single organism on a timescale of days: clonal selection and affinity maturation are natural selection of B-cell lineages, in which antibody-producing cells vary (through somatic hypermutation), are differentially reproduced according to how tightly they bind the antigen (the selection pressure), and the high-affinity survivors are retained and expanded — a textbook instance of the population, the discriminating pressure, and the heritable retention, distinguished only by the substrate and the speed.

Burnet sets out clonal selection: somatic mutation founds antibody-producing clones, and antigen contact drives proliferation of the matching clone, a selective advantage within one body.
“When mutational change occurs a new clone is initiated. ... the crucial one is the prolifera- tive response which allows a selective advantage to the clone”

- Pull Flow
- Immunology — antigen-pulled clonal expansion versus constitutive innate-immune surveillance.
This sourceFoundational statement that antigen encounter selectively pulls clonal expansion of matching lymphocytes — antigen-driven (pull) versus constitutive immune activity.

- Sparse Coding
- In the immune system, clonal selection activates a tiny matching subset of a vast naive lymphocyte repertoire per antigen.

Burnet posits many pre-existing clones each reactive to one determinant, with an introduced antigen stimulating only the corresponding clone, presumably a lymphocyte, to proliferate.
“This is the crux of the clonal selection hypothesis. It assumes that in the animal there exist clones of mesenchymal cells, each carrying immunologically reactive sites corres- ponding in appropriate complementary fashion to one (or possibly a small number of) potential antigenic determinants.”

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 4 of 6 citations: 1 supported, 3 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
