A hundred times every day I remind myself that my inner and outer life depend on the labours of other men living and dead and that I must exert myself in order to give in the same measure as I have received.

Science is the attempt to make the chaotic diversity of our sense-experience correspond to a logically uniform system of thought.

I am thankful for all of those who said NO to me. It’s because of them I’m doing it myself.

The whole of science is nothing more than a refinement of everyday thinking.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.

Our task must be to free ourselves... By widening our circle of compassion to embrace all living creatures and the whole of nature and it's beauty.
