"transgression," selection #10

Selection #10: Perhaps when contemporary philosophy discovered the
possibility of nonpositive affirmation, it began a process of
reorientation whose only equivalent is the shift instituted by Kant when
he distinguished the *nihil negativum* and the *nihil privatium*--a
distinction known to have opened the way for the advance of critical
thought. (_LCMP_, "Preface to Transgression," p. 36)

	1. where "the possibility of nonpositive affirmation" refers 
	   to a type of transgression that "does not transform the
	   other side of the mirror . . . into a glittering expanse"
	   (p. 35).
	2. I am unfamiliar with this way of referring to Kant via the
	   Latin terms *nihil negativum* and *nihil privatium*. Can
	   someone (with the time and inclination) translate?
