Scientific Revolution: How the Method of Understanding the World Changed

The Copernican Shift

In 1543, the dying Nicolaus Copernicus signed for publication "On the Revolutions of the Heavenly Spheres" — a book that placed the Sun at the center of the universe instead of the Earth. This was not just an astronomical adjustment — it was an attack on the entire system of knowledge inherited from Aristotle and Ptolemy.

The Ptolemaic system worked: it predicted the movements of the planets with acceptable accuracy, using epicycles — small circles on large circles. It was consistent with the physics of Aristotle (heavy bodies strive toward the center — which means Earth is in the center) and with biblical texts. Heliocentrism destroyed this system and demanded the creation of a new one.

Galileo Galilei (1564–1642) — a key figure. His telescope (1609) discovered the moons of Jupiter (meaning not everything revolves around the Earth), mountains on the Moon (meaning celestial bodies are as imperfect as earthly ones), phases of Venus (compatible only with heliocentrism). His trial by the Inquisition (1633) and imprisonment — a dramatic clash between emerging science and the institution of the Church.

Bacon and the Method

Francis Bacon (1561–1626) — philosopher of the scientific method. His "Novum Organum" (1620) — an answer to Aristotle: not deduction from principles, but induction from observations. "Knowledge is power" (Scientia est potestas). Science — an instrument of practical domination over nature.

Bacon described "idols" — prejudices interfering with scientific thinking: idols of the cave (personal prejudices), idols of the market (linguistic traps), idols of the theater (authority of systems), idols of the tribe (limitations of human nature). This is an early systematization of cognitive biases.

Newton (1643–1727) synthesized the work of Copernicus, Kepler, and Galileo in "Mathematical Principles of Natural Philosophy" (1687): three laws of motion + the law of universal gravitation explained both celestial mechanics and earthly motion in a unified system. "Hypotheses non fingo" ("I do not feign hypotheses") — principle: to describe facts mathematically, without seeking metaphysical causes.

Why This Matters

The scientific revolution changed not only knowledge about nature — it changed the very idea of knowledge. Before it: authority (Aristotle, Bible, Church Fathers). After it: experiment and mathematics as the criteria of truth. This shift set the trajectory for the next four centuries.

The Royal Society (London, 1660) and the French Academy of Sciences (Paris, 1666) — the first institutions dedicated to collective production of scientific knowledge. Publication, peer review, reproduction of experiments — the foundations of the scientific community formed at that time.

Question for reflection: The scientific revolution occurred in spite of institutional resistance (the Inquisition). Are there "Galileos" in your organization or industry — people with correct ideas, facing institutional resistance? How can you distinguish them from those who are simply wrong?
