Kenneth Reinhard: a much shorter quote

But it is only by means of risk taking, of undertaking acts
with unpredictable results, that new thought can emerge. If theory will
become more than the production of Code for the deciphering of Messages, more than the endless recycling of things we already know in always predictable new forms, it must break from the safety of familiar paradigms and calculated interventions.

There must be a throw of the dice for something new to emerge into the
world, and the desire of theory is for the production of new truths, not
for the repetition of old knowledge. Such truths are singular, momentary,
vanishing, and theory is the vision that discerns what is universal in
them, and holds fast to it. (Thinking With Shakespeare: Manifesto For Experimental Critical Theory)
