 Some philosophers have suggested a perceptual interpretation of natural revelation, according to which “intentional design” is a property that can be directly perceived in nature as well as in human behavior and art. Since intentional design by definition entails a designer, this means that our experiences of nature could give us immediate knowledge of the existence of a creator (Ratzsch 2003; Wahlberg 2012; Plantinga 2011: Ch. 8).
