Now the lad, on his side, was not guilty of error in respect of anyone: in practising he was not doing what he was forbidden but what he had been told to do, and he was not standing among those engaged in gymnastics when he threw the javelin, but in his place among the other throwers: nor did he hit the boy because he missed the target and sent his javelin instead at those standing clear. He did everything correctly, as he intended; and thus he was not the cause of any accident, but the victim of one, in that he was prevented from hitting the target.

The boy, on the other hand, who wished to run forward, missed the moment at which he could have crossed without being hit, with results which he by no means desired. He was accidentally guilty of an error which affected his own person, and has thus met with a disaster for which he had himself alone to thank. He has punished himself for his error, and is therefore duly requited; not that we rejoice at or approve of it—far from it: we feel both sympathy and sorrow.

It is thus the dead boy who proves to have been guilty of error; so the act which caused his death is to be attributed not to us, but to him, the party guilty of error: just as the recoiling of its effects upon the agent not only absolves us from blame, but has caused the agent to be punished as he deserved directly his error was committed.
