The Ghost in the Machine

In 'The Ghost in the Machine,' Arthur Koestler challenges conventional science by arguing that an inherent flaw in human evolutionary development leads to self-destructive tendencies.

The book critiques Cartesian dualism and behavioral psychology, introducing the concept of 'holons'—units that are both whole and part—to explain the complex interplay between rational and primal aspects of human nature.

Koestler delves into the mind-body problem, discussing how the human brain's evolutionary structure, with its retained primitive layers, can lead to conflicts between rational logic and emotional drives.

He also examines human aggression and its biological and environmental roots, concluding with a discussion on the potential for pharmacological solutions to mitigate these conflicts.
