The Anxious Outsider by Nathan Jones

Anxiety brings Dasein face to face with its ownmost Being-thrown and reveals the uncanniness of everyday familiar Being-in-the-world.
— Martin Heidegger in Being and Time (p. 342)
What can be said to characterize the Outsider is a sense of strangeness, of unreality.
— Colin Wilson in The Outsider (p. 14)
