This is a theoretical paper which applies feminist and ecological femi
nist critiques of the subject/object distinction in philosophy to Marx
's labour theory of value. It argues that much of the use of Marx's po
litical economy has been undermined by the centrality of the subject/o
bject distinction in his theory. His deployment of this distinction le
d him to an exclusive emphasis on subjective human labour-power as the
key factor in profit. The main part of the paper reworks Marx's value
-theory without the subject/object distinction. Used this way, the pap
er argues, Marx's value theory becomes a theory of time and speed, in
which nature overall is the source of value, and the time of natural r
eproduction is disregarded in the interests of profit. The paper conte
nds that this reworking of the labour theory of value extends its expl
anatory force.
