The central question in the philosophy of time is whether time is tensed or tenseless, viz., whether the moments of time are objectively past, present or future, or whether they are ordered merely by the tenseless temporal relations earlier than, simultaneous with, and later than. In this text and the companion volume "The Tensed Theory of Time: A Critical Examination", Craig appraises the arguments for and against the tensed and tenseless theories of time. The discussions range widely over issues in the philosophy of language, phenomenology, relativity theory, philosophy of space and time, metaphysics, and philosophy of religion. The Tenseless Theory of Time sets out to discover whether the ineliminability of tense from language and our experience of tense warrants a belief in its objective ontological status, or whether the defeaters raised by McTaggart's paradox and the Myth of Passage serve to undermine any warrant that the tensed theory of time may be supposed to enjoy.
