Where to Begin (a "Truth Project" worthy of the name)? (#4)

If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties. Francis Bacon, The Advancement of Learning (1605), Book I, v, 8. [Link on the right is to a free Kindle version - help yourself]

Over the years, my thinking on why I should bother have developed and gotten clearer.  Like most pithy sayings, Francis Bacon's overstates the case.  Still, I like it.
