"Philosophy of science without history of science is empty; history of science without philosophy of science is blind"
About this Quote
"Empty" is aimed at philosophers of science who build sleek accounts of method, rationality, and progress while treating actual scientific practice as an inconvenience. Lakatos had watched grand theories of confirmation and demarcation turn into armchair architecture: elegant, internally consistent, and unable to explain why science lurches, revises, and occasionally faceplants. Without history, philosophy becomes a sterile normative game, mistaking its tidy rules for how knowledge is really earned.
"Blind" is the counterpunch to historians who pile up archival detail yet refuse to judge, generalize, or say what counts as improvement. Lakatos is allergic to mere chronicle. Facts alone don't tell you what a "discovery" is, why a research program persists through anomalies, or how rival theories get evaluated. His subtext: refusing philosophy is not neutrality; it's smuggling in unexamined standards while pretending not to have any.
Context matters: writing in the shadow of Popper and Kuhn, Lakatos wanted a middle path that preserved rational critique without denying the messy, political, and time-bound character of science. The line works because it casts philosophy and history as mutually disciplining forces. Each keeps the other honest: history tests philosophy's claims against reality; philosophy prevents history from collapsing into anecdote.

Evidence: “Philosophy of science without history of science is empty; history of science without philosophy of science is blind”. (p. 91 (opening line; PSA Proceedings volume 1970, pp. 91–136)). This is a paraphrase of Kant used by Lakatos as the opening of his PSA Proceedings paper. Cambridge Core’s record for the PSA Proceedings volume explicitly places the article in Volume 1970 and gives the page range pp. 91–136; the quoted sentence appears in the displayed extract/opening. Note: some secondary references cite a later reprinting (e.g., 1971 in an edited volume), but the primary publication shown here is the PSA Proceedings (1970) with the line at p. 91.
