Sanders Peirce (1839–1914) was an American philosopher, logician, and mathematician. He founded three fields: semiotics (the study of signs), pragmatism (a theory of meaning based on practical consequences), and abductive reasoning (inference to the best explanation). He published the core statements of all three between 1867 and 1878.","status":"active","vx_hash":"cf02a4a9a001d5b0ba496aee55451f0c33b17d4a184b4965d7a49b4676f5a45d","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"976e6667e782a50e59ee1ea5bfa167fe68d5029b7bd0045b8e6a1a77e4677bc4","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:42:35.650Z","actor":"owner","text_sha":"bd1c8d1ef87e12135c54f51a89627122df0d267a4444568ed9f4c3369c3a7f35","detail":{"divided_from":"body","block":10,"kind":"p"},"prev":"genesis","hash":"976e6667e782a50e59ee1ea5bfa167fe68d5029b7bd0045b8e6a1a77e4677bc4"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:42:35.650Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/thinker-charles-peirce/d10"},{"id":"d11","kind":"h","type":null,"order":11,"text":"### Why It Matters","status":"active","vx_hash":"862197f02a37896d61ca6436bb88a2baf3df3a8d50679fabd19bf65bccc2e745","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"b66c64cb1083696d83976e09d77a7e54aea45970289a1e4b67c3a6d14c39b914","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:42:35.650Z","actor":"owner","text_sha":"a4819b750e1f362046048e66a2633f32de13b891cbecc89e4945f5a4a78ff266","detail":{"divided_from":"body","block":11,"kind":"h"},"prev":"genesis","hash":"b66c64cb1083696d83976e09d77a7e54aea45970289a1e4b67c3a6d14c39b914"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:42:35.650Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/thinker-charles-peirce/d11"},{"id":"d12","kind":"p","type":null,"order":12,"text":"Peirce built the vocabulary for describing what happens when one entity sends information to another.
