——〈在广州岭南学堂的演说〉，1912年5月7日
The biggest risk to our industry is not the energy transition itself, but being unprepared for it.
The notion of truth is not definable in any formal system that is strong enough to include arithmetic.
The coal industry must evolve or risk becoming obsolete. Adaptation is the key to survival.
If you don't fail at least 90 percent of the time, you're not aiming high enough.
过去不是异国，而是我们祖先的家园。
人类的愚蠢在于，总是把简单的事情复杂化。
我步入丛林，因为我希望生活有意义，我希望活得深刻，吸取生命中所有精华，把非生命的一切都击溃，以免当我生命终结，发现自己从没有活过。
