——1945年4月接到希特勒已死的消息时说

我已经注意到有爬山习惯的年轻人长大后通常有所作为。

无论一个人被认为多么自私，他的本性中显然存在某些原则，这些原则使他对别人的命运感兴趣，并将他们的幸福视为自己的必要，尽管他从中除了看到它时的快乐外一无所得。

Every life is in many days, day after day. We walk through ourselves, meeting robbers, ghosts, giants, old men, young men, wives, widows, brothers-in-love, but always meeting ourselves.

I'm not afraid to fail, I'm afraid of not trying.

The energy transition isn't a threat—it's an opportunity to reinvent ourselves.

Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.

"History is not just facts and dates; it’s the lives of people who lived them."

无论天塌了多少次，我们都得活下去。
