OverviewHow can parents, educators, business leaders and policy makers nurture creativity, prepare for inventiveness and stimulate innovation? One compelling answer, this book argues, lies in fostering the invention of imaginary worlds, a.k.a. worldplay. First emerging in middle childhood, this complex form of make-believe draws lifelong energy from the fruitful combustions of play, imagination and creativity. Inventing imaginary worlds develops the skills society needs for inventing the future.
