J. R. Wettersten: «Karl Popper and Critical Rationalism», i Internet Encyclopedia of Philosophy. 2007, seksjon 6: «Mario Bunge developed a non-justificationist theory of science, especially of physics, before he had ever heard of Popper, and he does not view his work a part of the project known as critical rationalism. It nevertheless can count as a version of critical rationalism: it is a non-justificationist effort to improve standards of criticism.» Lest 29. februar 2020.
