Deep dives

The Emergence of Consciousness

Consciousness is conceptualized as a concentrated example of life’s broader processes, which involve deep lineages of constructive trajectories. As humans evolved, a key survival skill was predicting the behavior of others, which led to the development of a theory of mind. This allowed for self-referential thinking, enabling conversations within ourselves about potential future outcomes. The complexity and abstraction of consciousness arise from our understanding of causal relationships embedded in our history, making it a natural extension of life’s processes.
