Words have determinable sense only within a complex of unstated assumptions, and all interpretation must therefore go beyond the given material. This book addresses what is man’s place in the Aristotelian world. It also describes man’s abilities and prospects in managing his life, and considers how far Aristotle’s treatment of time and history licenses the sort of dynamic interpretation of his doctrines that have been given. The ontological model that explains much of Aristotle’s conclusions and methods is one of life-worlds, in which the material universe of scientific myth is no more than an abstraction from lived reality, not its transcendent ground.
