The Idea of Progress: An Inquiry into Its Origin and Growth — Reading Notes

From Ancient Cycles to Modern Linearity

Bury begins by examining classical and early Christian views, which generally lacked a concept of indefinite human improvement. He notes that ancient thinkers often saw history as cyclical or degenerative, while early Christians focused on spiritual progress toward salvation, not earthly advancement. The turning point, he argues, came with the Renaissance and the Scientific Revolution, which gradually fostered a belief in cumulative knowledge and human capacity to improve material conditions. Bury carefully distinguishes between earlier notions of perfection in a static state and the modern idea of an open-ended, progressive future.

The Philosophers Who Shaped Progress

Bury dedicates substantial attention to French thinkers of the 17th and 18th centuries. He discusses the Abbé de Saint-Pierre, who proposed a scheme for perpetual peace and believed in the indefinite perfectibility of human institutions. More critically, he examines Rousseau's paradoxical stance: Rousseau argued that man's faculty of self-improvement led to the 'calamities of civilisation,' a view Bury finds too general and rhetorical. Bury also analyzes Condorcet, who in his Sketch for a Historical Picture of the Progress of the Human Mind envisioned ten stages of progress culminating in a future of equality and enlightenment. These figures, Bury shows, debated whether progress was inevitable or reversible.

The Role of Science and Industry

Bury highlights how the rapid advances in natural science and technology in the 19th century reinforced faith in progress. He points to the influence of Auguste Comte, who formulated a law of three stages (theological, metaphysical, positive) and saw sociology as the final science. Herbert Spencer extended evolutionary ideas to society, arguing that progress is a necessary cosmic process. Bury notes that these thinkers often conflated descriptive laws with normative ideals, a tension he keeps in view. The industrial revolution and its visible transformations made the idea of progress seem empirically grounded, yet Bury remains alert to the potential for this belief to become an 'idolum saeculi.'

Progress as a Secular Faith

In the later chapters, Bury examines how the idea of progress became a substitute for religious hope. He observes that the expectation of a 'happy state on this planet for future generations' replaced the hope of felicity in another world. This shift, he argues, gave progress a quasi-religious authority, making it the test by which social and political theories are judged. Bury does not endorse or condemn this development; instead, he traces its intellectual genealogy, showing how thinkers from Turgot to Spencer contributed to a doctrine that, by the early 20th century, had become almost unquestioned in Western thought.

Bury's study is not a defense of progress but a historical anatomy of an idea. Readers should attend to his method: he lets the thinkers speak through their own arguments, often quoting at length, and he is careful to note where evidence is incomplete or where later writers distorted earlier views. The book rewards those who read it as a series of intellectual portraits rather than a single thesis. Bury's own stance remains deliberately ambiguous, leaving the reader to judge whether progress is a valid guide or a modern idol.
