This is an animate lexicon, overflowing with pulsating and creative concepts. Van der Tuin and Verhoeff are engaged with what concepts can do, and what they can make happen, rather than trying to capture a spurious ‘classifixation’ of what they are. The authors do not so much offer definitions as stage a series of potentialities, novel directions in which to take concepts, or indeed, to be taken by them. The conceptual territory traversed is at once familiar and foreign, provoking feelings of the uncanny. This brilliant and seriously playful work enacts its own incitement to the reader: to connect, to create, to articulate, and to activate new ways of thinking-being, in the service of a vibrant future.
