The map follows up a talk to the Blackheath Philosophy Forum on 2 April 2011 by Huw Price, Professor of Philosophy and director of the Center for Time at Sydney University.☜F1CEB7

Is it better - from the impersonal viewpoint - to look asymmetries in time rather than a direction (to the future) of time?☜FFB597

Priority of spacetime geometry »Priority of spacetime geometryPriority of spacetime geometry☜The authors of the paper cited below claim that it is possible to define a cosmological arrow of time in a way that does not need to be reduced to non-temporal considerations - that is an intrinsic feature of spacetime, and which therefore has conceptual priority over the entropic approach.☜98CE71
