The question of the existence and the properties of time has been subject to debate for thousands of years. This considered and complete study offers a contrastive analysis of phenomenologies of time from the perspective of the problematics of the visibility of time. Is time perceptible only through the veil of change? Or is there a naked presence of 'time itself'? Or has time always effaced itself? McClure's new work also stages confrontations between phenomenology of time and analytical philosophy of time. By doing so he explores ancient issues from a fresh perspective, such as whether time passes, whether experimental time is 'real time', and whether the very concept of time is contradictory.
