Life, Albert Einstein

Let us not forget that knowledge and skills alone cannot lead humanity to a happy and dignified life. ... I claim credit for nothing. Everything is determined, the beginning as well as the end, forces over which we have no control. It is determined for the insects as well as for the stars, Human beings, vegetables or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.

- Albert Einstein (1879-1955)

Knowledge, Confucius

知之爲知之 不知爲不知 是知也。

- 孔子

When you know a thing, to hold that you know it; and when you do not know a thing, to allow that you do not know it - this is knowledge.
