The Demarcation Problem in Science

  • Chapter
Wittgenstein and Scientific Knowledge

Abstract

The problem of demarcating science from non- or pseudo-science has serious ethical and political implications for science itself and, indeed, for all societies in which science is practised. The conflicts and controversies surrounding the views of Copernicus, Galileo, Darwin or Lysenko make this abundantly clear. Sometimes these controversies involve what are generally regarded as non-scientific or political considerations. Examples of this are the banning of Copernicus’s theory by the Catholic Church, and the support of Lysenko’s position by the authorities in Russia in opposition to the neo-Darwinists. At other times, however, it is not the church, the state or the party that is involved in disputes about what is to be seen as science, but rather the scientific community itself. Much of the debate today concerning race and intelligence is regarded in some scientific circles as a debate concerning pseudo-scientific claims. The analyses and conclusions of those who claim a link between heredity and intelligence are viewed by some scientists as ‘pseudo-scientific’ and, consequently, these men are often defined as fakes, charlatans or pretenders by organised segments of the scientific community.

In science it is usual to make phenomena that allow of exact measurement into defining criteria for an expression; and then one is inclined to think that now the proper meaning has been found. Innumerable confusions have arisen this way. Ludwig Wittgenstein
