Well, I ask you, gentlemen, is it not extraordinary that, if he saw me riding on a saddled mule, he would hold his peace,—for what could he say? It would be natural for a cripple to ride about on a cheaply hired mule, if only he could afford it. —and then, because I mount borrowed horses, he should try to persuade you that I am able-bodied; and that my using two sticks, while others use one, should not be argued by him against me as a sign of being able-bodied, but my mounting horses should be advanced by him as a proof to you that I am able-bodied? For I use both aids for the same reason.
