“For the simple truth is that truth is often hard to come by, and that once found it may be easily lost again.”
From Allan Megill’s book Historical Knowledge, Historical Error.
Revising old notes, and this quote is the first one I wrote down. It was a mysterious once, because I don’t think that it was Allan’s quote by someone else’s. I found it on a page before the preface of the book. I really like it. It can be interpreted generally, or it can also be applied to history.
