Bacon's Scientific Method
Francis Bacon's Novum Organum (1620) established the foundational methodology of modern science: systematic inductive reasoning from empirical observation, controlled experiment, and skepticism toward inherited authority, replacing the Aristotelian deductive method (reasoning from first principles) with the modern experimental method (reasoning from accumulated evidence), and articulating for the first time that knowledge is power and that science's purpose is not contemplative understanding but practical domination of nature.
Before Bacon, the dominant scientific method was Aristotelian: begin with first principles (self-evident truths or definitions), reason deductively to conclusions, and organize knowledge into a logical hierarchy. This method could achieve internal consistency but could not correct false first principles, if your starting axioms were wrong, your conclusions would be wrong regardless of how rigorous your logic. Medieval scholasticism had spent centuries refining arguments from Aristotelian premises that were simply incorrect about the natural world.
Bacon's methodological revolution was to reverse the direction of reasoning. Rather than beginning with principles and deducing observations, begin with observations and induce principles. The experimental method, deliberately manipulating conditions to produce observations that test specific hypotheses, replaces armchair reasoning with systematic engagement with nature as it actually is. The idols of the mind (idola mentis) that Bacon identified, the Tribe (biases shared by all humans), the Cave (individual biases), the Marketplace (linguistic confusions), the Theatre (philosophical systems that distort reality), were a systematic taxonomy of the cognitive errors that deductive-authority methods could not correct but empirical methods could.
Bacon's philosophical contribution was equally significant: 'knowledge is power' (scientia potestas est) articulated a conception of knowledge as instrumental rather than contemplative. For Aristotle and the medieval tradition, knowledge of nature was valuable in itself as a form of understanding God's creation. For Bacon, knowledge was valuable because it enabled human control of natural processes, 'the enlarging of the bounds of Human Empire, to the effecting of all things possible.' This instrumental conception of science, knowledge as a tool for human domination of nature, is the philosophical foundation of technology and of the Industrial Revolution. Predictive History connects Bacon's program to Dante's humanism: the validation of human reason and human agency as legitimate ends, not merely means to theological contemplation.

What was Francis Bacon's contribution to science? ＋
The Novum Organum (1620) established experimental inductive method: begin with empirical observation and controlled experiments, induce principles from evidence, replacing Aristotelian deduction from first principles. Bacon identified systematic cognitive biases (idols of the mind) that deductive authority methods couldn't correct. His philosophical contribution: 'knowledge is power', science's purpose is practical domination of nature (enabling technology), not contemplative understanding. This instrumental conception is the philosophical foundation of the Industrial Revolution.
