ABSTRACT. Koch claims that the rudiments of cognitive adventures, conscious thought, the more elaborated forms of scientific reflection, all seem to follow a special path of dynamic heuristics. Schuh explains that, traditionally, morphology at the macroscopic level has formed the basis for most recognized taxonomic characters. Johnston argues that given what we know from the psychophysics of perception it follows that Revelation and Explanation cannot be true together (when it comes to the external explanatory causes of our color experience, psychophysics has narrowed down the options).
