Karl Marx's philosophical, political and sociological analysis of the worki
ngs of capitalism provides insights regarding the character of monetary val
ue (price) and the role of the market that are relevant to ecological econo
mists. Ecological economists are divided over the utility of pricing compon
ents of ecological systems and the potential role of the market in achievin
g ecologically sustainable societies. In the Marxian-influenced socialist m
ovements of the 19th and 20th centuries, similar issues were raised by thos
e preoccupied with organising state policy and manipulating the market to a
chieve social justice. For example, at particular points in the Russian and
Cuban revolutionary processes, the potential and limitations of monetary p
ricing and market exchange were debated in a heated and detailed way. In as
much as ecological economists hold certain interests in common, it is wort
h reflecting on Marx's view of the human role within nature and analysing t
he discussions and experiences of Marxian experimenters in social transform
ation that relate specifically to exchange. (C) 2001 Elsevier Science B.V.
