Let’s explore this neuroscientific perspective and critique Descartes’ dualistic approach to understanding consciousness. **Descartes’ Mind-Body Dualism** In the seventeenth century, Descartes posited that the mind, responsible for thought and consciousness, is separate from the physical body. This dualism was revolutionary, highlighting the mind’s role in defining human experience. Descartes argued that while the body operates mechanically, the mind is a non-physical entity that governs consciousness, making humans unique. **Neuroscience and the Emergence of Consciousness** Contrary to Descartes, contemporary neurosc...
