[Foucault-L] Enlightenment and Imagination

Hello,

In 'What is Enlightenment?' in reference to the promotion of new forms of
subjectivity and Baudelaire, Foucault says: "imagine it [reality/the
present] otherwise than it is."

I'm wondering if anyone has come across any texts that examine the concept
of "imagination" in Foucault and its status in his idea of critical
thought?

Many thanks,

Paul Rekret
