To none of these evidences of a fearful tragedy of a long dead day did little Tarzan give but passing heed. His wild jungle life had inured him to the sight of dead and dying animals, and had he known that he was looking upon the remains of his own father and mother he would have been no more greatly moved.

Your insults to myself can be endured, / I am a philosopher and am inured. / But there are insults that I will not swallow / That you have levelled at our gods.

As Tom Paine warned, inuring us to lies lays the groundwork for many other evils.
