Lyotard's motivation is different than it would be for us in psychology. In 'Lessons in paganism' (The Lyotard Reader, Basil Blackwell, Inc. '89) Lyotard states that the pagan gods 'openly intended to deceive, openly duplicitous. They talked in order to produce certain effects, not in order to profess the truth' (p. 136) and 'They always call their gods "the strongest", because they know that they have the upper hand when it comes to cunning' (p. 137). 

This focus is necessary because Lyotard is talking about politics (totalitarianism, capitalism).  In 'One thing at stake in women's struggles' (same book), he talks about 'the ruse of reason' which is masculine (p. 112) and not a good thing the
way I read it as he ends with "One day a UN vote will denounce as male sexism the primacy accorded theoretical discourse to the great scandal...of us all" (p. 120). 

Lyotard:
"Women disappear into the male cycle, integrated either as workers into the production of commodities, or as mothers into the reproduction of labour power, or again, as commodities: themselves (cover-girls, prostitutes of
mass-media, hostesses of human relations), or even as administrators of capital (managerial functions)." (p. 116) 

Now, isn't that worthy of a new topic? It gives us some sense of what Lyotard thinks about the women's issue.
