Importance of Francis Bacon's Novum Organum
Francis Bacon's Novum Organum proposed a new approach to scientific inquiry based on experience and observation, marking the beginning of the modern scientific method. Bacon emphasized the importance of starting from simple sensuous perception and using a method that reconciles our desire for simple and true explanations of the world with the complexity and messiness of reality. His method laid the foundation for scientific inquiry, which seeks to understand the workings of the world through observation, reasoning, and the production of reliable accounts.
The Evolution and Debates about Scientific Method
The development of scientific method can be traced back to the ancient Greeks, such as Plato and Aristotle, who discussed the importance of empirical observation and reasoning. Aristotle's method drew on both mathematics and natural philosophy, examining both the causes and essences of things. Influenced by these traditions, Bacon's method proposed starting with observation and experience. Galileo, following Bacon's approach, emphasized the importance of experimental sciences and the rejection of mere hypotheses. Isaac Newton further built on these ideas and introduced rules for scientific reasoning, such as deductive logic and the need for universal causes and principles.
Inductive and Deductive Reasoning in Scientific Method
Scientific method involves two types of reasoning: inductive and deductive. Deductive reasoning involves starting with certain premises and deducing conclusions that are guaranteed to be true if the premises are true. Inductive reasoning, on the other hand, allows us to go beyond the premises and draw conclusions that generalize beyond observed instances. While deductions are used to test theories, inductions involve generalizing from specific cases to form hypotheses. However, the debate between philosophers like John Stuart Mill and William Whewell revealed differing views on the role of induction and hypothesis in scientific method, highlighting the challenges in establishing universal principles for scientific inquiry.
Karl Popper and Falsification as a Criterion for Scientific Method
Karl Popper proposed a shift in scientific method by emphasizing falsification rather than induction. He argued that scientific hypotheses should be formulated in a way that they are potentially falsifiable. A hypothesis should not aim to confirm itself through accumulating positive instances but should undergo rigorous testing to identify potential falsifiers. Popper's view challenged the notion of science as a progressively accumulating body of confirmed truths and focused on the importance of rigorous testing and efforts to falsify hypotheses. However, the question of whether there is a single scientific method or how different sciences employ diverse methods remains controversial, with ongoing debates about the nature and principles of scientific inquiry.
Melvyn Bragg and his guests discuss the evolution of the Scientific Method, the systematic and analytical approach to scientific thought. In 1620 the great philosopher and scientist Francis Bacon published the Novum Organum, a work outlining a new system of thought which he believed should inform all enquiry into the laws of nature. Philosophers before him had given their attention to the reasoning that underlies scientific enquiry; but Bacon's emphasis on observation and experience is often seen today as giving rise to a new phenomenon: the scientific method.The scientific method, and the logical processes on which it is based, became a topic of intense debate in the seventeenth century, and thinkers including Isaac Newton, Thomas Huxley and Karl Popper all made important contributions. Some of the greatest discoveries of the modern age were informed by their work, although even today the term 'scientific method' remains difficult to define.With: Simon SchafferProfessor of the History of Science at the University of CambridgeJohn WorrallProfessor of the Philosophy of Science at the London School of Economics and Political ScienceMichela MassimiSenior Lecturer in the Philosophy of Science at University College London.Producer: Thomas Morris.
