A useful work of political ecology
MARTIN GRAHAM recommends a book that makes a critique of neoclassical economics and attempts to envision a sustainable global future

The Physics of Capitalism: How a New Political Ecology Can Change the World
by Erald Kolasi
Monthly Review Press £27.99
READERS who struggle with the maths and abstractions inherent in the physics of the 20th and 21st centuries — Einstein, Niels Bohr and all that flowed from their work — should not be deterred by the title of this book.
Erald Kolasi draws only on classical physics to show how energy flows determine the fate of complex systems, including economic systems and life itself. It also equips him to provide a devastating critique of neoclassical economics and enables him to give us a vision of a sustainable global future — all without resorting to a single equation!
