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.
Our moods do not believe in each other. To-day I am full of thoughts, and can write what I please. I see no reason why I should not have the same thought, the same power of expression, to-morrow. What I write, whilst I write it, seems the most natural thing in the world; but yesterday I saw a dreary vacuity in this direction in which now I see so much; and a month hence, I doubt not, I shall wonder who he was that wrote so many continuous pages. Alas for this infirm faith, this will not strenuous, this vast ebb of a vast flow! I am God in nature; I am a weed by the wall.

The Physician, by the study and inspection of urine and ordure, approves himself in the science; and in like sort should our author accustom and exercise his imagination upon the dregs of nature.
The kingdom of man over nature, which cometh not with observation,--a dominion such as now is beyond his dream of God,--he shall enter without more wonder than the blind man feels who is gradually restored to perfect sight.
The world, nature, human beings, do not move like machines. The edges are never clear-cut, but always frayed. Nature never draws a line without smudging it.
