What we see depends mainly on what we look for. (John Lubbock, 19th century British politician and philanthropist)

Lubbock’s statement should be a warning to the honest student and researcher. When we set out to find answers to puzzles, we begin with pre-conceived ideas that too often influence the solutions we find. An open mind and disciplined procedures are necessary to discover truth. And make sure you start with reliable sources of information.

Have I not [taught] you to be honest and to speak the truth, so that you bring back truthful reports to those you serve? (Proverbs 22:20-21)
