THREE:The case of infanticide suggests similar thoughts. When we remember that both Plato and Aristotle commended as a valuable social custom that which we treat as a crime; when we recall the fact that the life of a Spartan infant depended on a committee of elders, who decided whether it should live or perish, we shall better appreciate the distance we have travelled, or, as some would say, the progress we have made, if we take up some English daily paper and read of some high-minded English judge sentencing, at least formally, some wretched woman to death, because, in order to save her child from starvation or herself from shame, she has released it from existence. Yet the feeling, of which such a sentence is the expression, is often extolled as one of the highest triumphs of civilisation; and the laws, as if there were no difference between adult and infant[76] life, glory in protecting the weakness of a child by their merciless disregard for the weakness of its mother.In order that a punishment may attain its object, it is enough if the evil of the punishment exceeds the advantage of the crime, and in this excess of evil the certainty of punishment and the loss of the possible advantage from the crime ought to be considered as part; all beyond this is superfluous and consequently tyrannical. Men regulate their conduct by the reiterated impression of evils they know, not by reason of evils they ignore. Given two nations, in one of which, in the scale of punishments proportioned[167] to the scale of crimes, the severest penalty is perpetual servitude, and in the other the wheel; I say that the former will have as great a dread of its severest punishment as the latter will have; and if there be any reason for transporting to the former country the greater penalties of the other, the same reasoning will serve for increasing still more the penalties of this latter country, passing imperceptibly from the wheel to the slowest and most elaborate tortures, nay, even to the last refinements of that science which tyrants understand only too well.
