One of the most respected psychologists in the Slavic world—where materialist prejudices are less pronounced—Prof. Victor Petrenko, a member of the Russian Academy of Sciences, discusses his views on the nature of mind and reality. He shows, through remarkable experiments, that our very perception is conditioned upon our ability to tell ourselves, conceptually, what we are perceiving. It is possible that we simply do not perceive what we have no conceptual categories to make sense of. This way, we may be immersed in effectively alien aspects of reality that we cannot cognize. This captivating essay introduces to a Western audience the high-quality—and arguably less metaphysically biased—scholarship of the Slavic world in an area of knowledge whose relevance to our lives cannot be overestimated.
