Is the conscious mind just the brain or something more? Can science explain consciousness?
Consciousness. It's a phenomenon that makes humans different from robots, but how exactly does it happen?
In this Ted Talk neuroscientist Anil Seth argues that consciousness is a controlled hallucination. Having less to do with intelligence than we often think, consciousness depends on how the brain predicts its world to operate. Since the brain cannot directly access the external stimuli it perceives (the brain must perceive stimuli through the senses), the reality it creates is thus a two way street: with it taking in electrical signals produced by physical objects and it projecting out its predictions onto the physical world. For this reason, the brain sometimes misinterprets physical reality, and "hallucinates" in the sense that its predictions (that are not physically there) become irrestible, even, to hear, sense, or see. Using several images that exploit certain cerebral failings, Seth confounds his audience in his explanation of how this happens.

Human are conscious, billiard balls are not, and computers aren't either. But all three are just collections of molecules, aren't they? What is consciousness, and does it go beyond what science
What kinds of contact can the mind have with the world? Can we know how the world is in itself, or can we only know shadows of the world in our own minds? Are we trapped behind a veil of our own
Modern science tells us that the mind is just the brain working. But science cannot yet tell us how consciousness, rationality, free will, autonomy, or even our sense of self arises out of the mer
Is the human mind a relatively inflexible program bequeathed to us by evolution, and culture just a veneer that gives age-old urges a respectable cover?
