What Counts as Consciousness

🌈 Abstract

The article discusses the views of neuroscientist Christof Koch on consciousness and the nature of the mind, particularly in relation to integrated information theory (IIT). It explores how Koch's ideas challenge the dominant computational and physicalist views of the mind, and how he sees consciousness as the fundamental reality rather than just an emergent property of the physical brain.

🙋 Q&A

[01] Christof Koch's Exploration of Consciousness

1. What are the key ideas that Christof Koch explores in his new book?

• Koch ventures into the challenging landscape of integrated information theory (IIT), a framework that attempts to compute the amount of consciousness in a system based on the degree to which information is networked.
• He grapples with the question of how our thoughts, which seem ethereal and without physical properties, can have real-world consequences.

2. How does IIT differ from other philosophical views on the mind-body problem?

• IIT says that consciousness is the only thing that truly exists for itself, and that consciousness is the fundamental reality, rather than just an emergent property of the physical brain.
• IIT argues that consciousness is the ability of a system to have causal power upon itself, which can be objectively measured, unlike the traditional mind-body dualism or physicalist views.

3. How does IIT relate to the idea of panpsychism?

• IIT is not the same as panpsychism, which says that everything, even elementary particles, has some form of consciousness.
• IIT suggests that consciousness may exist on a gradient, and that even simple systems like bacteria may have a rudimentary form of consciousness, but it does not attribute consciousness to everything in the same way as panpsychism.

[02] Consciousness and Computation

1. How does Koch view the relationship between consciousness and computation or simulation?

• Koch argues that simply simulating a brain or system is not the same as it being conscious. Just as simulating a rainstorm does not actually get anything wet, simulating a brain does not necessarily mean the simulation is conscious.
• He believes that unless a machine is built in the image of the human brain, using neuromorphic engineering or quantum computing, it will not achieve human-level consciousness, even if it can outperform humans in many tasks.

2. What is Koch's view on the consciousness of large language models (LLMs)?

• According to Koch, LLMs may be able to do everything humans can do, and perhaps even better, but they will never be truly conscious, as they lack the necessary causal structure and connectivity of the human brain.
• He argues that LLMs are essentially "vampires" that suck up human creativity and spit it out again, without any real consciousness or subjective experience.
