Will Durant examines the historical roots of the social problem, demonstrating that great philosophers have always viewed philosophy as an instrument for social reconstruction rather than abstract speculation.
In the opening sections, the author traces how civilizations undergo recurring cycles of rebarbarization. As a society accumulates wealth, a leisure class develops, speculation undermines traditional dogma, and individualism dissolves the social fabric. To avert collapse without resorting to external coercion, thinkers have continually sought to forge a natural, rational ethic.
Durant explores the Socratic doctrine that intelligence is virtue, arguing that true morality consists not in blind conformity to group rules, but in the intelligent coördination of individual desires. When a person clearly understands their true advantage, they perceive that social behavior and personal development converge.
Plato approaches the social problem through politics, viewing the creation of philosopher-kings as the essential condition for a harmonious state. Durant details Plato's vision of universal education designed to discover genius, alongside a structured social order where each individual functions according to their natural capacity.
Francis Bacon shifts the focus from abstract contemplation to the social possibilities of science. Durant emphasizes Bacon's call to organize research internationally and treat nature as raw material for the amelioration of human misery. Knowledge is power, and science must become an art applied to social control.
Spinoza defends popular sovereignty and freedom of thought, arguing that absolute liberty of expression is vital for social vitality. Durant explores Spinoza's view that the state's ultimate end is freedom from fear, enabling human beings to live under the direct guidance of reason rather than blind emotion.
Finally, Nietzsche challenges prevailing democratic morality, which he views as a product of herd weakness. Durant outlines Nietzsche's conception of the will to power, the aristocratic order of rank, and the cultivation of superior individuals as the true goal of human evolution.
In the concluding chapters, Durant reflects on contemporary social panaceas such as socialism, eugenics, and anarchism, ultimately arguing that the primary solution to human misery is the organized spread of informed intelligence.
