Rene Descartes, the legendary philosopher who gave us the phrase 'I think, therefore I am', genuinely believed that the human soul physically interacted with the body through the pineal gland. While mapping out the foundations of modern rationalism and analytical geometry, he randomly concluded that this tiny, pinecone-shaped structure in the center of the brain was the mystical seat of human consciousness. He hypothesized that the soul sat in this gland like a tiny pilot, directing 'animal spirits' through the nervous system to control the muscles like an incredibly fleshy marionette puppet. While modern science has proven the pineal gland simply regulates melatonin for sleep, New Age gurus still furiously sell supplements designed to decalcify this exact same gland to unlock your hidden psychic superpowers
