Reviews of previous editions

'It is entirely characteristic that Chris Brown's text is unlike anybody else's; it is equally characteristic that it is written with a zest, a pace and a sense of fun that is sadly missing from much of the discipline as a whole. Students - and their teachers - will gain a great deal from it. They will also have a good time!' - N.J. Rengger, Political Studies

'[A] very appealing book... The text succeeds in giving a clear account of all the main theoretical possibilities and, in a non-judgemental but not uncritical way, setting them in context... I can think of no book more likely to succeed in persuading a sceptical undergraduate - someone convinced of the existence of a self-evident world of facts - that not only is a knowledge of theory necessary to understand international relations, but it is fun.' - James Mayall, Review of International Studies
