Abstract

In a series of carefully argued and stimulating papers on realism, Usakli Maki has pointed out that economic theories typically are unrealistic in two senses: by violating "the-whole-truth" and "nothing-but-the-truth" (Maki 1989, 1992b, 1994b). He suggests that realism in economics can still be rescued by regarding theories as partially true descriptions of essences and as lawlike statements about tendencies. In this chapter, I defend realism by an alternative strategy: idealizational (or "isolational") statements are counterfactual conditional (Niiniluoto 1986), and the concepts of truth and truthlikeness can be applied to them (Niiniluoto 1987). Further, false but sufficiently truthlike theories may be taken to refer to real entities in the world (Niiniluoto 1997, 1999).
