Two things fill the mind with ever new and increasing admiration and awe, the oftener and more steadily we reflect on them: the starry heavens above me and the moral law within me.
有两样东西,人们越是经常持久地对之凝神思索,它们就越是使内心充满常新而日增的惊奇和敬畏:我头上的星空和我心中的道德律。
The best reactions are those that work the first time and every time.
The free, exploring mind of the individual human is the most valuable thing in the world.
