Thought is the strongest thing we have. Work done by true and profound thought - that is a real force.

We cannot understand what happens in the universe. What is glorious in it is united with what is full of horror. What is full of meaning is united to what is senseless. The spirit of the universe is at once creative and destructive — it creates while it destroys and destroys while it creates, and therefore it remains to us a riddle. And we must inevitably resign ourselves to this.

Knowing all truth is less than doing a little bit of good.

When we observe contemporary society one thing strikes us. We debate but make no progress. Why? Because as peoples we do not yet trust each other.

We should all be thankful for those people who rekindle the inner spirit.

Example is leadership.

We must never allow the voice of humanity within us to be silenced. It is humanity's sympathy with all creatures that first makes us truly human.
