It has been my experience that seeking the “truth” (in the spiritual sense) is as much about faith as it is about fact.
I’ve seen many bitter and sour people who spent too much of themselves worrying about what is “true”….I have seen many of the things that people are capable of doing to each other and I am far from naive, so I’m not preaching “sunshine and daisy’s”. However, as I see things, reality and “truth” in human terms are different from “evidence” or scientific truth/fact. I think that the “Things Worth Believing In” are the unquantifiable human belief in things such as love, courage, freedom, justice, good prevailing over evil, etc. Certainly, when we are talking about policy and law we need to consider scientific fact, but on an individual basis, I think that happiness is more about what we choose to believe.
No triumph of the human spirit was ever founded in cynicism. We all believe in something, and those beliefs, rightly or wrongly held , are the lens through which we live out our lives. If someone want’s to see life as nothing but chemical reactions and electrical impulses, be my guest. I will choose to believe otherwise.
