Lines to Liars by Irving Sidney Dix — Read

Let lawyers harp about the law, / And all its majesty and might; / They find in every case a flaw / And think they're right.

Let politicians praise the truth / And laud its virtue to the sky -- / They practice from their very youth / To give the lie.

Let prophets send the saints to heaven / And damn poor sinners e'en to hell -- / How such authority is given / They cannot tell.

Let doctors prate of human pain / Alleviated by their skill, / When Death's dull sickness comes, in vain / Is every pill.

Let poets pipe of bloody war / And claim its carnal method right; / They're only piping cowards, for / Not one will fight.

And so it seems we mortals boast / Of knowledge where we know the least / And show our ignorance the most / Like any beast.
