Terry Pratchett visited Trinity last December to receive an honorary doctorate, the Saturday of his visit he spoke in the exam hall. The reason I am remembering this is on Sunday I found out a friend of mine reads Discworld books to his girlfriend, over the phone, this particular little bit of news caused much laughter and slagging at the time. But back to Pratchett, news had come out a few weeks previous of his diagnosis with a form of alzheimer's disease so the chance to see him speak was an opportunity not to be missed. The hall itself was packed and the talk itself was interesting, excluding the extreme fan questions, which exposed more nerdiness than should be exposed in a public setting.
What stuck with me was something Pratchett said about religion and the power of humanity. He, as a devout atheist, broke from the question and answer format of the interview/audience for the longest time when he spoke on this issue. He remarked that we should have more fascination with streetlights then with stars. Stars, are simply huge formations of gas revolving millions of kilometers away fusing helium. They are a natural phenomenon that have been around longer than the human species and probably will be around far after we wipe ourselves out. Streetlights, however, are the culmination of many many fortunate and wonderful coincidences. Streetlights mean that a few billion generations ago one cell became two, and a few million generations later something slipperry and gooey crawled out of the primordial ooze and onto dry land. Millions of generations later an earlier version of us came out of the trees and walked on two legs. A few thousand generations hence humans really came into being. Fast forward a few thousand more generations and someone though to light the dark streets. A tall metal pole, ornate or functional, is built; the magic of human ingenuity then facilitated the lighting of a wick, or nowadays an electric element. Then there was light and the streets were dark no more. Putting faith in human achievement and the potential brilliance of us as a species seems so simple and yet night after night people the world over gaze at stars. Pratchett's point is that all the genius of the world is right there in front of our eyes, yet we keep looking to things very very unimaginably far away.
