In this book Rorty wanted to convince people that ‘relativism is a bugbear’ and that discarding dualisms will help bring us together. Trust, social cooperation and social hope, he says, are where our humanity begins and ends. The most praiseworthy human capacity is to trust and cooperate with other people; to work together to improve the future. He urges us to substitute hope for the sort of knowledge that philosophers try to attain, to substitute imagination for certainty, and to substitute curiosity for pride. Hope (rather than truth) is the ability to believe that the future will be unspecifiably different from, and unspecifiably freer than the past. It is a condition of growth and the direction of growth is unpredictable.
