(New) 23 - 28 August 2027, 2027 Congress of Logic, Methodology and Philosophy of Science and Technology, Kobe [JP]

Date: 23 - 28 August 2027
Location: Kobe [JP]
Deadline: Sunday 15 November 2026

CLMPST is the premier forum on Logic, Methodology and Philosophy of Science and Technology. Its aim is to bring together active researchers in this broad field. CLMPST has a long history — it started in 1960, and has been held every four years since then in capital cities and/or by leading university centres in this field. Recent previous CLMPST Congresses were held in Buenos Aires (2023), Prague (2019), Helsinki (2015), Nancy (2011), and Beijing (2007).

Welcomed are papers and symposia from across all areas of logic, philosophy of science, and philosophy of technology. The aim is to feature presentations from across the wide array of topics pertaining to our fields, from mathematical logic to metaphilosophy, from the foundations of the exact sciences to philosophy of the humanities and social sciences, from philosophy of technology to historical perspectives on the sciences, presented by researchers from around the world. CLMPST is particularly enthusiastic about proposals that reach across disciplines, that incorporate speakers from different countries or regions, that explore public engagement and/or social implications of academic work, or that reflect on relationships and contributions of different knowledge systems.
