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?

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.

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here a somewhat unsystematic list of six types of cases in which we should be inclined to say of a theory t1 that it is superseded by t2 in the sense that t2 seems—as far as we know—to correspond better to the facts than t1 , in some sense or other.

- 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.
