Another great scientist who said things which made me wonder and marvel was the late Richard Feynman, possibly one of the most entertaining scientists ever (U Tube viewing will confirm that).
I don't feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is as far as I can tell, possibly, it doesn't frighten me.
It is much more likely, that the reports of flying saucers are the results of the known irrational characteristics of terrestrial intelligence rather than the unknown rational effort of extra-terrestrial intelligence.
I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong.
Thanks Bob. I like the first and third quotes the best. I think these appeal to my "existential" side, because I share the sentiment that I'd rather not know, than now something incorrectly, falsely. Doubt is hard to live with, but untruth seems to me a case of "that way madness lies." I think, generally humans are built for truth...at some evolutionary level anyway. If we (the species) didn't have a pretty accurate "map" of the world we probably wouldn't survive, or wouldn't have survived as long as we have. (Of course the is always room for improvement, more accurate "maps".) I Like the Feynman quotes. Thanks for sharing them.
