'''Imre Lakatos''' (9 November 1922 – 2 February 1974) was a philosopher of science whose work addressed scientific rationality, theory change, and the evaluation of competing research frameworks. He examined how scientific theories develop over time through structured sequences rather than isolated hypotheses.

His work sought to reconcile historical accounts of science with normative standards of rational appraisal.

== Early life and education ==
Lakatos was born in Debrecen, Hungary. He studied mathematics, physics, and philosophy in Hungary before leaving the country following political upheavals in the post-war period.

He later settled in the United Kingdom, where he pursued academic work in philosophy.

== Philosophy of mathematics ==
Lakatos examined the development of mathematical knowledge through historical case studies. In ''Proofs and Refutations'', he analyzed how definitions and proofs evolve through criticism, counterexample, and revision.

This approach treated mathematics as a dynamic practice rather than a static body of truths.

== Methodology of scientific research programmes ==
Lakatos proposed that scientific theories develop within research programmes characterized by a “hard core” of commitments and a “protective belt” of auxiliary hypotheses. He argued that research programmes should be evaluated over time based on their problem-solving progress.

This framework was intended as an alternative to both strict falsificationism and descriptive historicism.

== Relationship to Popper and Kuhn ==
Lakatos engaged critically with the work of Karl Popper and Thomas S. Kuhn. He sought to retain Popper’s emphasis on criticism while incorporating Kuhn’s attention to historical patterns of theory change.

His methodology was presented as a synthesis rather than a replacement.

== Relationship to institutions ==
Lakatos held academic positions in the United Kingdom, including at the London School of Economics. He participated actively in seminars and debates on the philosophy of science.

Much of his work was published posthumously from lectures and manuscripts.

== Limits and uncertainty ==
Lakatos’s research programme methodology has been criticized for ambiguity in its evaluative criteria. Critics question how progressiveness should be measured in practice.

There is no consensus on the scope of its applicability across scientific domains.

== Status ==
Imre Lakatos is regarded as a significant figure in twentieth-century philosophy of science. His work continues to be discussed in debates on scientific methodology and theory change.
