 Psychological research, moreover, indicates that teleological beliefs about nature come natural to humans. Some even argue that humans are “intuitive theists” (Kelemen 2004; Barrett 2012). A related consideration in favor of design-perception is that it could potentially explain why beliefs about design in nature are so widespread and often held so persistently, even though they have turned out to be hard to justify by argument (Ratzsch 2003: 135–136).
