McKenna's theory of cognition

Terence McKenna’s theory of cognition suggests that human consciousness evolved through interactions with psychoactive plants, which expanded our mental capacities and perception. He believed that these substances unlocked innate cognitive abilities, enabling us to access deeper levels of understanding, creativity, and spiritual insight. According to McKenna, this process shaped not only individual awareness but also cultural and societal development, revealing that our mind's potential is vastly greater when influenced by these natural tools. Essentially, he viewed altered states of consciousness as a vital part of human evolution and perception.
