The Merger of Knowledge with Power: Essays in Critical Science is a book written in 1990 by Jerome Ravetz.

"We can best understand this anthology as a 20-year continuation of his seminal study, Scientific Knowledge and Its Social Problems".

The Chapter "Ideological Commitment in the Philosophy of Science' offers Ravetz's first hand reading of the relevance of ideology in the philosophies of science of Karl Popper, Thomas Kuhn, Imre Lakatos and Paul Feyerabend.

Ravetz also presents his insight on the use of ignorance ("Usable Knowledge, Usable Ignorance: Incomplete Science with Policy Implications"; the book is credited[2] with having provided the first illustration of ‘science-based ignorance’, p. 26), the Gaia hypothesis, how to constructively tackle the problems of quality control of quantitative information, and the need for "A new social contract for science".

For Carrozza (2015) [3] this book (p. 284) investigates the two interrelated processes of the scientization of politics and of the politicization of expertise "in the spirit of a general call for renewing the social contract between science and society".
