 The second scientific anti-realist argument a person would be well-advised not to use in support of constructive empiricism is the Pessimistic Induction Argument. This argument points out that scientific theories in the past have been shown to be false, so by induction, we should think that current theories are false, too. If this argument is taken to have the conclusion that belief in our current theories is irrational, then, as above, the argument is incompatible with any voluntarism the constructive empiricist might embrace. The argument is also incompatible with the view of a constructive empiricist who, in the skeptical spirit of anti-realist views in general, rejects reasoning based on a principle of induction. Van Fraassen, for instance, writes: “I do not think that there is such a thing as Induction, in any form” (2007, 343).
