Does Scientific Discovery Have a Logic?

Abstract

It is often claimed that there can be no such thing as a logic of scientific discovery, but only a logic of verification. By ‘logic of discovery’ is usually meant a normative theory of discovery processes. The claim that such a normative theory is impossible is shown to be incorrect; and two examples are provided of domains where formal processes of varying efficacy for discovering lawfulness can be constructed and compared. The analysis shows how one can treat operationally and formally phenomena that have usually been dismissed with fuzzy labels like ‘intuition’ and ‘creativity’.
