"The principles of logic and mathematics are true simply because we never allow them to be anything else. And the reason for this is that we cannot abandon them without contradicting ourselves, without sinning against the rules which govern the use of language, and so making our utterances self-stultifying. In other words, the truths of logic and mathematics are analytic propositions or tautologies."

While it is a very hard and sometimes very cruel profession, my love for the bike remains as strong now as it was in the days when I first discovered it. I am convinced that long after I have stopped riding as a professional I will be riding my bicycle. I never want to abandon my bike. I see my grandfather, now in his seventies and riding around everywhere. To me that is beautiful. And the bike must always remain a part of my life.
