I think that if the beast who sleeps in man could be held down by threats — any kind of threat, whether of jail or of retribution after death — then the highest emblem of humanity would be the lion tamer in the circus with his whip, not the prophet who sacrificed himself. But don’t you see, this is just the point — what has for centuries raised man above the beast is not the cudgel but an inward music: the irresistible power of unarmed truth, the powerful attraction of its example.

Boris Pasternak (1890-1960) Russian poet, novelist, and literary translator

I think that if the beast who sleeps in man could be held down by threats -- any kind of threat, whether of jail or of retribution after death -- then the highest emblem of humanity would be the lion tamer in the circus with his whip, not the self-sacrificing preacher. But don’t you see, this is just the point -- what has for centuries raised man above the beast is not the cudgel but an inward music: the irresistible power of unarmed truth, the attraction of its example.

I think that if the beast dormant in man could be stopped by the threat of, whatever, the lockup or requital beyond the grave, the highest emblem of mankind would be a lion tamer with his whip, and not the preacher who sacrifices himself. But the point is precisely this, that for centuries man has been raised above the animals and borne aloft not by the rod, but by music: the irresistibility of the unarmed truth, the attraction of its example.
