Being and Time
The conservative British writer Roger Scruton called (2002) "Being and Time" a "description of a private spiritual journey" rather than genuine philosophy. But Stephen Houlgate (1999) compares Heidegger's achievements in "Being and Time" to those of Kant and Hegel. Simon Critchley writes (2009) that it is impossible to understand developments in continental philosophy after Heidegger without understanding "Being and Time".
