When to Form an Opinion

From Hugh Nibley:

At what point does one have "a right to an opinion"? I have never reached that point yet, and yet I go right on having opinions. I have been having them ever since I was a child and knew nothing at all; and I still go right on having them now that I am old and know nothing at all. The ideal thing would be to withhold opinions until all the returns are in, but as Karl Popper reminds us, that day will never come. So there is nothing for it but to go ahead and have our premature opinions, gratefully selecting in support of such the evidence we like best.... What is not permitted is to make one's choice on the authority of someone else. If you are not concerned in the matter, don't bother to take a position; but once you have decided to be concerned, you must make your own decision, no matter how limited your knowledge. All of us have eaten of the Tree of Knowledge, not just the Authorities, and each is accountable for his own decisions: you cannot delegate free agency even for a moment. You may go to the expert for information, and that is what he is good for, but not for a final opinion. ("Of All Things" p. 221, a Hugh Nibley quote book edited by Gary Gillum, 2nd edition.)
