IDEAS: How to think about science

If science is neither cookery, nor angelic virtuosity, then what is it?

Modern societies have tended to take science for granted as a way of knowing, ordering and controlling the world. Everything was subject to science, but science itself largely escaped scrutiny. This situation has changed dramatically in recent years. Historians, sociologists, philosophers and sometimes scientists themselves have begun to ask fundamental questions about how the institution of science is structured and how it knows what it knows. David Cayley talks to some of the leading lights of this new field of study.

There was an IB student who came to the library to look up the printed version of The Encyclopedia of Britannica everyday before the due day of his TOK assignment because he found the chapters about Knowledge very helpful. You may also want to give it a try!
