Deep dives

The Nature of Morality

Morality is rooted in physical and chemical processes within the brain, rather than being a supernatural concept. Contrary to the belief that morality derives from religious teachings, it emerges as a natural consequence of our neurological state. For example, feelings of pleasure from cooperation and pain from harming others indicate that moral judgments are directly linked to how these actions affect our brain states. Thus, understanding the biology of our brains offers a more reliable foundation for evaluating moral actions than ancient religious texts.
