The choice for mankind lies between freedom and happiness and for the great bulk of mankind, happiness is better.

The only real voyage of discovery consists not in seeking new landscapes, but in having new eyes.

"The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion."

Science should be accessible to everyone, regardless of background.

The only way to achieve true freedom is through self-discipline.

只有为别人而活，生命才有价值。

外表不端正，是因为没有培养好德行；内心不精诚，是因为没有修治好心灵；端正外表、修养德性，才能了解万物。

Once you label me you negate me.

无知者是不自由的，正因和他对立的是一个陌生的世界。
