The best moral sanction is that of conscience; the worst is the fear of punishment.

最好的道德约束力是良心， 最坏的则是害怕惩罚。

The fear of punishment remains as to its substance.

对惩罚的恐惧仍是其核心问题。

Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.

人如果需要用对刑罚的惧怕来约束，需要对死后才能受到的回报所期望，那就确实可怜了。
