My scientific work is motivated by an irresistible longing to understand the secrets of nature and by no other feeling. My love for justice and striving to contribute towards the improvement of human conditions are quite independent from my scientific interests.
Man, when living, is soft and tender; when dead, he is hard and tough. All animals and plants when living are tender and delicate; when dead they become withered and dry. Therefore it is said: the hard and tough are parts of death; the soft and tender are parts of life.
"In the woods we return to reason and faith. There I feel that nothing can befall me in life~~no disgrace, no calamity (leaving me my eyes), which nature cannot repair."
Flower in the crannied wall,
I pluck you out of the crannies,
I hold you here, root and all, in my hand,
Little flower-but if I could understand
What you are, root and all, all in all,
I should know what God and man is.
