This monograph is a detailed study and systematic defence of the Growing Block Theory of time
(GBT) first conceived by C.D. Broad. The book offers a coherent logically perspicuous and
ideologically lean formulation of GBT defends it against the most notorious objections to be
found in the extant philosophical literature and shows how it can be derived from a more
general theory consistent with relativistic spacetime on the pre-relativistic assumption of
an absolute and total temporal order.The authors devise axiomatizations of GBT and its
competitors which against the backdrop of a shared quantified tense logic significantly
improves the prospects of their comparative assessment. Importantly neither of these
axiomatizations involves commitment to properties of presentness pastness or futurity. The
authors proceed to address and defuse a number of objections that have been marshaled against
GBT including the so-called epistemic objection according to which the theory invites
skepticism about our temporal location. The challenge posed by relativistic physics is met
head-on by replacing claims about temporal variation by claims about variation across
spacetime.The book aims to achieve the greatest possible rigor. The background logic is set out
in detail as are the principles governing the notions of precedence and temporal location. The
authors likewise devise a novel spacetime logic suited for the articulation and comparative
assessment of relativistic theories of time. The book comes with three technical appendices
which include soundness and completeness proofs for the systems corresponding to GBT and its
competitors in both their pre-relativistic and relativistic forms.The book is primarily
directed at researchers and graduate students working on the philosophy of time or temporal
logic but is of interest to metaphysicians and philosophical logicians more generally.
