Abstract

The article covers the problem of testability of intelligent design theory. The objection that intelligent design theory does not correspond to principle of methodological naturalism is discussed. I show that recognizing intelligent causes is commonly applied in science. I present the "specification-complexity" criterion, an attempt to generalize the criteria used to define the problem in particular sciences. This criterion - together with the concept of explanatory filter - is to guarantee the testability of intelligent design theory. The irreducible complexity criterion, which is to recognize design in biology, is brought forward. The problem of progressiveness of intelligent design theory is also reported. The analysis leads to the conclusion that functioning in intelligent design theory criterion of design recognition belongs to probability and complexity theory and that theory discussed is empirically testable
