Abstract
We argue that in order to avoid the timelessness of block universe models, that are manifestly inconsistent with our conscious perception of the flow of time, we should try to formulate models in which all times (all now's) cannot consistently be unified into a single well defined mathematical object incorporating all time. In other words, theorists should intentionally try to build a certain kind mathematical inconsistency into their models, in order to thwart the possibility of `blockification'.
