<p>Difficult classics . . . Immanuel Kant’s stuff is supposed to be notoriously difficult (then again a lot of philosophy is) . . . so is reading Chaucer’s Canterbury Tales in its original English. I’d also add Moby Dick or Gravity’s Rainbow by Thomas Pynchon (I have no idea what it’s about).</p>
<p>Also works by Cormac McCarthy. My friend was raving about one of his books and I decided to check one out. I tried reading it and was like " . . . wth?"</p>
<p>If you want something plain difficult, try your library’s tax dictionary.</p>
