Construction and Truth-Value of Scientific Knowledge
By Michel Morange
What is common knowledge? How different is it from scientific knowledge? In the first part of his lecture, Michel Morange questions the notion of knowledge and distinguishes it from belief. He also points out a philosophical ideology about the relative value of knowledge and discusses its ability to help scientists reach reality. He then explains in which ways scientific knowledge is different from common knowledge and uses the examples of the Greek philosophers, Louis Pasteur and Karl Popper to support his claim. Scientific knowledge, he says, is a search for natural explanations; it results from a long historical process. Morange ends his lecture by asking a question to the audience: is intelligent design a scientific theory?
