When I was a kid, truth seemed simple. Over the last sixty years I learned that truth is not really simple at all. Truth can be surprisingly elusive, and finding it can require a whole lot of intelligence, energy and time.
Some devote their entire lives to finding truth. They search for decades in the hope of discovering the truth about tiny slices of our reality. Think of astronomers, particle physicists and cancer researchers. Some philosophers have devoted their careers to thinking critically about the very meaning of truth. Those explorers are the vanguard in the quest for truth.
For most of us truth is more mundane than the study of cosmology and the meaning of life. "It's raining"; "I'm hungry"; "that shirt doesn't fit me well"; "it's dark out". Statements like these are easily verified. We measure truth with our eyes, our gut, our skin.
When it comes to things that others tell us, truth is more complicated, though we can usually verify what we are told. I test your honesty when you tell me "It's raining". Your coat is wet, I see the rain, I know it's true. As I learn that you speak the truth, I come to trust you. Once I trust you I simply accept what you tell me in the same way as when I see the rain myself. The truth we speak, and the trust we earn and share, are the bricks and mortar of our society.
How is the truth complicated?
