This is an extract from an article by Brother Guy Consolmagno of the Vatican Observatory. Reading the whole piece offers another insight into telling the truth. It has to do with listening as well as speaking. Follow the link above for Brother Guy’s thoughts on truthfulness in science.
Conversation, the transmission of information, is the heart of science.
That’s one difference between the real scientists and the wanna-be’s. The email writers are sure they are right; we know we aren’t, completely, and never will be. And that’s what gives us courage to believe we’re not imposters. Science is not the truth, but the search for truth.
Pope Francis understands that. “We ought never to fear truth, nor become trapped in our own preconceived ideas, but welcome new scientific discoveries with an attitude of humility.”
[I once heard my grad school buddy Cliff Stoll say: “Data is not information, information is not knowledge, knowledge is not understanding, understanding is not wisdom.”]
