 The main problem for those who choose option (c) is that they have to spell out what is meant by a non-universal law (statement) and how it can perform similar explanatory and predictive tasks as a universal law. A convenient way to reconstruct the debate about option (c) is to understand non-universal laws as statements that are qualified by a ceteris paribus (henceforth, “cp”) clause. Yet, how to understand the meaning of the cp-clause is an open question that is answered differently by various philosophers.
