Politics, love, art and science are four sources of truth that Alain Badiou and Fabien Tarby discuss in their dialogues, gradually approaching philosophy. Who is left and who is right today, what do Mao and Stalin mean to us? Why is there always masculine and feminine in love? What is an art event? Does science really threaten the “oblivion of existence”? Answering these and many other questions, Alain Badiou not only shares his opinion, but shows how his philosophy works and where it leads. For the first time, Alain Badiou not only speaks out about this or that event, but gives the reader the opportunity to look at his system as a whole.
