I was browsing through my shelves for a good read, and found a copy of Thomas Hobbes’ Leviathan – bought nearly 23 years ago in Oxford.
Flipped it open and saw this note from my friend Travis:

Being the oaf I was I had foolishly tried to debate him on the utility of knowledge, and why certain things were worth learning “more” than others (“My engineering will beat your philosophy up, Travis!”). He showed me the error of my ways, after which I had promptly trotted down Broad Street and bought a couple of philosophy books from Blackwell’s, one of which was Leviathan.
Thank you, Travis. I stand corrected.
