All comedy probably arises from our enjoyment of other people's mistakes. If we did not make mistakes, there would be nothing in the world to laugh at. Hence, if we regard laughter as a blessing, we should pay a tribute to error. In the history of t he world the man who makes mistakes has never been sufficiently appreciated. For all the mirth he has given us we have repaid him with the basest ingratitude. Of this ingratitude you will find evidence if you turn to punch and look carefully at its admirable weekly collection of the errors of journalists and printers. Not long ago, it was Punch's custom to give the name of the paper from which the misprint or mis-statement was taken. You would imagine t hat any journalist or printer would have felt honoured as one who added to the gaiety of the most heavily taxed of nations. But it was otherwise, protests poured into the punch office. In a world that rightly appraised error, the newspapers would protest against this an attempt to rob them of the credit of having increased human happiness.
