My Lord Bacon, in his Novum Organum, discusses this point, and investigates with his habitual brilliance the various categories of evidence, and finds them all flawed. None conveys certainty, he decides, a conclusion which (one might think) would be devastating for scientists and lawyers alike: historians and theologians have learned to live with this, the former modestly tempering their claims, the latter resting their glorious edifice on the more reliable foundations of revelation. For without certainty what is science except glorified guesswork? And without the conviction of certainty, total and absolute, how can we ever hang anyone with an easy conscience? Witnesses can lie and, as I know myself, even an innocent can confess a crime he did not commit.But Lord Bacon did not despair, and claimed one instance of a fingerpost which points in one direction only, and allows of no other possibility. The perfectly independent eyewitness, who has nothing to gain from his revelation, who is, in addition, schooled in observation and report through a gentlemanly status and education, this is the nearest we can get to a reliable witness and his testimony may be said to be conclusive, overwhelming all lesser forms.
