The Ancient Origins of Consciousness: How the Brain Created Experience — Todd E. Feinberg & Jon M. Mallatt — 2015

Feinberg and Mallatt argue that consciousness is a natural biological phenomenon that evolved in early animals with complex nervous systems.

Using neuroscience, evolution, and philosophy, they trace when experience first appeared and identify the brain structures and behaviors that make consciousness possible.

⭐ Star Facts — The Ancient Origins of Consciousness

(Todd E. Feinberg & Jon M. Mallatt)

• Consciousness = “something it is like to be” an organism (subjective experience)
• It is a natural biological phenomenon, not something separate from the brain
• The “hard problem” is really a set of multiple explanatory gaps, not just one
• Four core features of consciousness: qualia, unity, referral, mental causation
• Consciousness requires complex, centralized nervous systems
• It emerges when brains create internal representations (mental images) of the world
• Consciousness likely began during the Cambrian explosion (~520 million years ago)
• Early vertebrates were among the first conscious organisms
• All vertebrates are conscious, not just humans or mammals
