人类一向有这个独特之处：它保留了两套法则——一套私下的，一套真正的；一套公开的，一套矫揉造作的。

思想的多样性推动创新——这是不容商榷的。

People, even more than things, have to be restored, revived, reclaimed and redeemed;never throw out anyone.

林业创新不是可选的——它对生存至关重要。

The growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs. ― George Eliot, Middlemarch

We are what we think. All that we are arises with our thoughts. With our thoughts, we make the world.
