Quantitative geography: Revolution or counter-revolution?

There has been a crisis of the so-called “quantitative geography” for a few years. It is partly due to a poor use of mathematics, often presented for its own sake. There are also deeper reasons: refusal of rational formalization; and more emphasis on social and political studies.This paper tries to snow that a formal language (i.e., vocabulary and syntax) is necessary. Linguistics show how a language can be perverted by ideology into a myth. This has happened with traditional geography and is still present in some recent radical studies.
