A lifeboat for consciousness

Posted by in category: neuroscience

I recently began to worry that something/someone, some field, force, disease, prion, virus, bad luck and/or natural causes could threaten and perhaps destroy the most valuable entity in the universe, an entity more valuable than life itself. Consciousness. What good is life extension without conscious awareness? What is consciousness?

We know the brain works a lot like a computer, with neuron firings and synapses acting like bit states and switches. Brain-as-computer works very well to account for sensory processing, control of behavior, learning and other cognitive functions. These functions may in some cases be non-conscious, and other times associated with conscious experience and control. Scientists seek the distinction – the essential feature, or trick for consciousness.

Some suggest there is no trick, consciousness emerges as a by-product of cognitive computation among neurons. Others say we don’t know, that consciousness may indeed require some feature related to, but not quite the same as neuron-to-neuron cognition.

In either case, humans and other creatures could in principle become devoid of consciousness while maintaining cognitive behaviors, appearing more-or-less normal to outside observers. Such hypothetical non-conscious behaving entities are referred to in literature, films and philosophical texts as ‘zombies’. Philosopher David Chalmers introduced the philosophical zombie, a test case for whether or not consciousness is distinct from cognitive neurocomputation.

David Papineau: How Does Consciousness Connect Us To Reality?

Posted by in category: neuroscience

Listen to this episode from Mind Chat on Spotify. Keith and Philip interview David Papineau (Professor of Philosophy at King’s College London) about his recent book ‘The Metaphysics of Sensory Experience’. David is also a materialist who believes in consciousness, so there’ll probably be a big old fight about that too.

Quantum mechanics and the puzzle of human consciousness

Posted by in categories: quantum physics, robotics/AI

Some scientists speculate that the strange happenings in this microscopic realm may hold the key to understanding consciousness. But scant evidence has left the majority skeptical.

That includes Christof Koch, Ph.D., meritorious investigator at the Allen Institute. As he wrote in his recent book, Then I am myself the world, “the brain is wet and warm, hardly conducive to subtle quantum interactions.”

Ned Block — What’s the Meaning of Consciousness?

Posted by in categories: evolution, neuroscience

Listen to audio versions of your favorite interviews with the Closer To Truth podcast: https://shorturl.at/hwGP3

Only about consciousness can we be 100 percent sure. That consciousness exists almost everyone agrees. What consciousness means—that’s where arguments and disputations arise. Must consciousness have ‘meaning’? Or can consciousness be a random accident, selected by evolution, the ‘foam on the waves’ of brain activity. But consciousness seems so radically vital.

Dan Dennett: Sir Roger Penrose Is WRONG About Human Consciousness!

Previous guest and friend of the show, Sir Roger Penrose, argues that human consciousness is not algorithmic and, therefore, cannot be modeled by Turing machines. In fact, he believes in a quantum mechanical understanding of human consciousness. However, as with any issue related to human consciousness, many disagree with him. One of his opponents is Daniel Dennett, with whom I recently had the pleasure of talking. Tune in to find out why Dennett thinks Penrose is wrong!

Thinking of Consciousness as Waves

Posted by in category: neuroscience

First written: Dec 14, 2018, Last update: Jan 2, 2019.

How can we think about the relationship between the conscious and the physical? In this essay, I wish to propose a way of thinking about it that might be fruitful and surprisingly intuitive, namely to think of consciousness as waves.

The idea is quite simple: one kind of conscious experience corresponds to, or rather conforms to description in terms of, one kind of wave. And by combining different kinds of waves, we can obtain an experience with many different properties in one.
