We are alone

We are alone:

"What is the implication of the possibility, mounting a bit every day, that we are alone in the universe?...It means that we have a job to do, a mission that will last all our ages to come: to seed and then to shepherd intelligent life beyond this pale blue dot."

Karl Sabbagh:

"I used to believe that there were experts and non-experts and that, on the whole, the judgment of experts is more accurate, more valid, and more correct than my own judgment. But over the years, thinking — and I should add, experience — has changed my mind. What experts have that I don't are knowledge and experience in some specialized area. What, as a class, they don't have any more than I do is the skills of judgment, rational thinking and wisdom."
