Why is there something rather than nothing? The article examines the theories that require realization of physical potentialities and, moreover, of whatever is thought of as possible. This marks the transition from substantive thinking to modal thinking. One discerns here a new philosophical paradigm operating a totally new set of problems and supported by contemporary development of cosmology.
