Neuroscience and the Nature of Color

The video explores the intersection of neuroscience and philosophy, particularly in the context of consciousness. It discusses how neuroscience often relies on philosophical assumptions and uses empirical data to revisit old debates. The nature of color is examined through different philosophical and scientific lenses, with an ecological perspective being advocated. The video also touches on skepticism about the external world and how neuroscience approaches this issue, emphasizing the subjective nature of experience.
