«– Is it hard to do philosophy?
– It's murder, absolutely. I compare it ... if you really want to know how to do it, you get up in the morning, there's a large brick wall and you run your head against that brick wall. And you keep doing that every day until eventually you make a hole in the wall. That's what it feels like.» (John Searle)In John Searle Interview: Conversations with History; Institute of International Studies, UC Berkeley, http://globetrotter.berkeley.edu/people/Searle/searle-con2.html
