Morals and the Evolution of Man

A philosophical treatise written in the early 20th century. The work explores the concept of morality from various perspectives, including biological, social, and psychological angles. Nordau argues that morality is not an inherent characteristic of human nature but rather a construct arising from societal needs and interactions. He examines the complexities of moral philosophy and critiques the views of various moral theorists throughout history. At the start of the book, Nordau presents an intriguing analogy involving a pike and a tench in a segregated aquarium to illustrate the phenomenon of morality. He discusses how the pike repeatedly attempts to attack the tench despite the presence of an invisible barrier, signifying the limitations imposed by moral compulsion. This sets the stage for Nordau’s broader inquiry into human behavior, where he challenges the notion of inherent good and evil in humanity, suggesting that morality evolves as a response to social structures and needs. His critical examination of historical ethical theories reveals the struggle between instinctual behavior and moral reasoning, prompting deeper reflections on why individuals often suppress their natural desires for societal approval and self-control.
