I spent much of my working life around newspapers, and the newspaper business teaches a particular way of thinking: before you believe anything, find out who is stating what they believe to be fact and how they that particular fact is true.
That way of thinking did not weaken my faith. It sharpened it. A conviction that has been thoroughly examined carries much more weight than one that goes unvetted.
Evidence and humility
The best publishers I worked with held two things in common: They were willing to be persuaded by evidence, and they were unwilling to pretend that every claim carried equal weight. That combination is rarer than it sounds, and it is exactly what our current culture is missing.
When I finally sat down to write The Book on the Shelf, I wrote it the way a good editor would have wanted it written. Show the sources. Anticipate the objection. Do not win the argument by leaving something out.
