At the beginning of the third millennium, the social "exchange" value of creativity is becoming greater and greater. In a worldwide landscape which has been altering at an uncontrollable speed, the individual is called upon to manage not only his or her private chronotope but also its almost daily changes in a child-like, fresh, versatile, original manner. At the same time, however, the individual is also called upon to find solutions to older problems by traveling new roads; problems such as the issue of coexistence on this planet, on which the future of the survival of the species now seems to be at stake. In the present volume, Creative Problem Solving, the bibliography of theoretical and research issues - which are, by their very nature, intertwined and multileveled - have been revised and enhanced.
