You can’t know

To know the truth of it, only they who make the deed can tell. Despite of this all of those whom smugness doth enfold will claim to be the learned ones, and mock those whose opinions they dispel. Yet through guesses, tales or fights that ever side engage none closer to the truth become. Their little minds that rule their soul shall tell them they have the sum. But still there only be the one who knows the truth and likely they shan’t tell. Even the company that they keep some doubts they cannot quell.
