[Foucault-L] What Is Enlightenment?

[Russ Anderson <russ.d.anderson@xxxxxxxxx>]

Hi all,
One quick question: does anyone have handy a publication date for  
Foucault's paper 'What is Enlightenment?'

I know that "What is Critique?" was published in 1978, and that he  
takes up Kant's paper again in the 1982-83 lectures at the College,  
but I cant seem to find a date for "What is Enlightenment?" other than  
its 1984 translation into English in The Foucault Reader.

Much appreciated,
Russell
