Recent disclosures regarding the relationship between Heidegger's thou
ght and his own version of National Socialism have led me to rethink m
y earlier efforts to portray Heidegger as a forerunner of deep ecology
. His political problems have provided ammunition for critics, such as
Murray Bookchin, who regard deep ecology as a reactionary movement. I
n this essay, I argue that, despite some similarities, Heidegger's tho
ught and deep ecology are in many ways incompatible, in part because d
eep ecologists-in spite of their criticism of the ecologically destruc
tive character of technological modernity-generally support a ''progre
ssive'' idea of human evolution.
