Wasn't Popper a falsificationist? Then why did he try to develop ideas about corroboration and versimilitude - the extent to which a theory was closer to truth than another theory? Isn't this verging dangerously close to verificationist territory? In our fourth ep on Chapter 10 in C&R, we wrestle with Popper's treatment of verisimilutude, both the formal and informal versions. Did the project fail? Was Popper out of his mind? Does this invalidate everything? We discuss Murders with ball-peen hammers Walking the line between verification and falsification Is science only after truth? Verisimilutude and its formalization Why the formalization fails Popper's three requirements for the growth of knowledge Popper's ratchet and the no ad-hoc rule Quotes Like many other philosophers I am at times inclined to classify philosophers as belonging to two main groups—those with whom I disagree, and those who agree with me. - C&R, page 309 I shall give here a somewhat unsystematic list of six types of cases in which we should be inclined to say of a theory t1 that it is superseded by t2 in the sense that t2 seems—as far as we know—to correspond better to the facts than t1 , in some sense or other. t2 makes more precise assertions than t1 , and these more precise assertions stand up to more precise tests. t2 takes account of, and explains, more facts than t1 (which will include for example the above case that, other things being equal, t2 ’s assertions are more precise). t2 describes, or explains, the facts in more detail than t1 . t2 has passed tests which t 1 has failed to pass. t2 has suggested new experimental tests, not considered before t 2 was designed (and not suggested by t1 , and perhaps not even applicable to t1 ); and t 2 has passed these tests. t2 has unified or connected various hitherto unrelated problems. - C&R, page 315 Let me first say that I do not suggest that the explicit introduction of the idea of verisimilitude will lead to any changes in the theory of method. On the contrary, I think that my theory of testability or corroboration by empirical tests is the proper methodological counterpart to this new metalogical idea. The only improvement is one of clarification. - C&R, page 318 Socials Follow us on Twitter at @IncrementsPod, @BennyChugg, @VadenMasrani Come join our discord server!
