A people without children would face a hopeless future; a country without trees would face a future with even less hope.

Stories you read when you're the right age never quite leave you. You may forget who wrote them or what the story was called. Sometimes you'll forget precisely what happened, but if a story touches you it will stay with you, haunting the places in your mind that you rarely ever visit.

——《中国人之直言》（1920年4月3日）

【译文】圣人的道理，平坦得就像大路一样，学者苦于不能得其人门的要领。

科学没有捷径，只有脚踏实地。
