How did the rules of scientific inquiry change over time?

The history of the scientific method traces how natural philosophers and scientists developed rules for reasoning, empirical observation, and hypothesis testing. Rather than following a straight line, this history features recurring debates over rationalism, inductivism, and realism. Thinkers from ancient Greece and India to the modern era have argued for different approaches to establishing scientific knowledge.

What we know

• Rationalist explanations of nature and atomism appeared in ancient Greece through Leucippus and Democritus, and in ancient India via the Nyaya, Vaisheshika, and Buddhist schools, while Charvaka materialism rejected inference in favour of empiricism. [1, 2]
• Aristotle helped pioneer early scientific method in ancient Greece by combining empirical biology and logic, and by rejecting a purely deductive framework in favor of generalizations drawn from natural observations. [1, 2]
• Major debates in the history of the scientific method include René Descartes' advocacy for rationalism, Isaac Newton's promotion of inductivism, and the 19th-century rise of hypothetico-deductivism. [1, 2]
• In the mid-20th century, some prominent philosophers argued against the existence of any universal rules of science altogether, differing from earlier views that sought a fixed methodological framework. [1, 2, 3] · medium confidence

Still open

• Mid-20th-century philosophers debated whether any universal rules of science actually exist, questioning the idea of a fixed methodological framework.
