Abstract
William Blattner is surely right that not enough scholarly attention has been paid to one of Heidegger's most central and most important philosophical notions: “originary temporality”. Blattner's exhaustive effort to lay bare and scrutinize Heidegger's arguments regarding temporality and time in Being and Time and in other early texts is impressive, and he offers several valuable new readings and insights. Yet, regrettably, Blattner tries too hard to trump Heidegger. He is bent on showing that Heidegger “failed” in his thinking about temporality and time, and his overly polemical account mars an otherwise illuminating discussion of Heidegger's texts.
