When we came within sight of the sea, the waves on the horizon, caught at intervals above the rolling abyss, were like glimpses of another shore with towers and buildings.
There is something good in all weathers. If it doesn't happen to be good for my work today, it's good for some other man's today... and will come around for me tomorrow.
But I go with my friend to the shore of our little river, and with one stroke of the paddle, I leave the village politics and personalities, yes, and the world of villages and personalities behind, and pass into a delicate realm of sunset and moonlight, too bright almost for spotted man to enter without novitiate and probation.
All things are flowing, even those that seem immovable. The adamant is always passing into smoke. The plants imbibe the materialswhich they want from the air and the ground. They burn, that is, exhale and decompose their own bodies into the air and earth again. The animal burns, or undergoes the like perpetual consumption. The earth burns, the mountains burn and decompose, slower, but incessantly.
Nature is a rag-merchant, who works up every shred and ort and end into new creations; like a good chemist, whom I found, the other day, in his laboratory, converting his old shirts into pure white sugar.
I can see others in the sunlight; I can see our boats' crews and our athletic young men on the glistening water, or speckled with the moving lights of sunlit leaves; but I myself am always in the shadow looking on. Not unsympathetically, - God forbid! - but looking on alone, much as I looked at Sylvia from the shadows of the ruined house, or looked at the red gleam shining through the farmer's windows, and listened to the fall of dancing feet, when all the ruin was dark that night in the quadrangle.
Reason must approach nature with the view, indeed, of receiving information from it, not, however, in the character of a pupil, who listens to all that his master chooses to tell him, but in that of a judge, who compels the witnesses to reply to those questions which he himself thinks fit to propose. To this single idea must the revolution be ascribed, by which, after groping in the dark for so many centuries, natural science was at length conducted into the path of certain progress.
It is not necessarily those lands which are the most fertile or most favored in climate that seem to me the happiest, but those in which a long struggle of adaptation between man and his environment has brought out the best qualities of both.
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.
