The Political Spectrum

The political spectrum is a representation of differing political positions in relation to each another. A familiar representation is the traditional horizontal axis representing left - moderate - right.

A more complex spectrum developed by Dickenson shows how various political positions relate to each other:1

Dickenson's Political Spectrum

Definitions for terms describing political positions, such as "progressive," "liberal," and "conservative" are not universally accepted. Political scientist and philosopher W.B. Gallie calles them contested concepts:3

… concepts the proper use of which inevitably involves endless disputes about their proper uses on the part of their users [that] cannot be settled by appeal to empirical evidence, linguistic usage, or the canons of logic alone.
