Time has been the forgotten dimension in the debate on the post-secular, originated by the philosopher Jürgen Habermas in the Social Sciences two decades ago.This article proposes a study of post-secularity from the temporal dimension and concludes that it is possible to affirm that post-secularism is a way of colonialism by other means.The article also inquires into the capacity of the post-colonial approach to offer a critical reading of political religiosity that would include the underlying cultures of time.In response to this question, it explains the controversial nature of post-colonial thought with respect to this task.However, it argues that post-colonial and de-colonial perspectives are nonetheless useful for apprehending cultures of time among religious actors.
