ABSTRACT
The advantage of retaining the traditional metaphors of law, validity, and governing is that it allows one to bring forward grounds other than empirical ones for the truth of a scientific statement—namely, arguments for why the objects in question must behave as the statement asserts. It may be somewhat puzzling to see the terms "statement" and "assert" used together with "law" and "govern"; as we said before, correspondence is a certain moment within the concept of scientific truth. The concept of validity must be added: Science makes construction possible because it contains the laws which govern the behavior of certain objects. The validity of the theory of classical hydrodynamics for Newtonian fluids is shown by the fact that it structurally implies a relation defining this type of fluid. The truth, however, does not change; whenever nature is thematized within the same context, one arrives at the same results.
