Abstract

The paper is a reply to g s robinson's criticism in "analysis," volume 31, Of popper's attempt to clarify the notion of scientific progress in terms of verisimilitude. I argue that robinson (1) misunderstands popper's account of basic statements, (2) confuses verisimilitude with probability (despite popper's explicit warnings), And (3) fails to understand the sense in which popper claims that verisimilitude is objective.
