To exhibit quasi-scientific objects in an art museum is not a new phenomenon. However, both experts and visitors repeat the same behavior familiar to each of them. It causes a deadlock situation. In order to avoid this deadlock, I propose that we must approach such exhibits from the so-called ‘semantic view’ of scientific theories. First, I point out that the problem from M.C. Beardsley's traditional aesthetics comes from his ‘classical’ view of scientific theories. Second, I introduce the ‘semantic’ view of scientific theories and its key concept of model, a concept that solves the problem of the classical view. Then, I show that, if visitors apply the semantic view to quasi-scientific exhibits, visitors could benefit and would be liberated from the deadlock. At the same time, I argue against objections to the semantic view. I also discuss my proposal.
