If things go on as they do, what with inventing and using new methods for killing people, we all need to become tardigrades to survive. I remember the to do when the American astronauts arrived at the moon and I never had a special reason to doubt it, but if you do, who live nearer NASA one would have to look better into it.
I think skepticism is sound where it helps us to examine better dubious statements(wheter they are news, propaganda or cientific truths). It is not sound if it goes so far that it disturbs our every day reability on our senses.
I think one of the major chalenges to our thinking systems will happen, if we discover or are discovered by developed creatures of other planets, which have different thinking systems.
It is a pity that there are no posts on the "astronomy thread" any more.
