April 16, 1855.--I realized this morning the prodigious effect of climate on one’s state of mind. I was Italian or Spanish. In this blue and limpid air, and under this southern sun, the very walls smile at you. All the chestnut trees were en fete; with their glistening buds shining like little flames at the curved ends of the branches, they were the candelabra of the spring decking the festival of eternal nature. How young everything was, how kindly, how gracious! the moist freshness of the grass, the transparent shadows in the courtyards, the strength of the old cathedral towers, the white edges of the roads. I felt myself a child; the sap of life mounted again into my veins as it does in plants. How sweet a thing is a little simple enjoyment! And now, a brass band which has stopped in the street makes my heart leap as it did at eighteen. Thanks be to God; there have been so many weeks and months when I thought myself an old man. Come poetry, nature, youth, and love, knead my life again with your fairy hands; weave round me once more your immortal spells; sing your siren melodies, make me drink of the cup of immortality, lead me back to the Olympus of the soul. Or rather, no paganism! God of joy and of grief, do with me what Thou wilt; grief is good, and joy is good also. Thou art leading me now through joy. I take it from Thy hands, and I give Thee thanks for it. April 17, 1855.--The weather is still incredibly brilliant, warm, and clear. The day is full of the singing of birds, the night is full of stars, nature has become all kindness, and it is a kindness clothed upon with splendor. For nearly two hours have I been lost in the contemplation of this magnificent spectacle. I felt myself in the temple of the infinite, in the presence of the worlds, God’s guest in this vast nature. The stars wandering in the pale ether drew me far away from earth. What peace beyond the power of words, what dews of life eternal, they shed on the adoring soul! I felt the earth floating like a boat in this blue ocean. Such deep and tranquil delight nourishes the whole man, it purifies and ennobles. I surrendered myself, I was all gratitude and docility. April 21, 1855.--I have been reading a great deal: ethnography, comparative anatomy, cosmical systems. I have traversed the universe from the deepest depths of the empyrean to the peristaltic movements of the atoms in the elementary cell. I have felt myself expanding in the infinite, and enfranchised in spirit from the bounds of time and space, able to trace back the whole boundless creation to a point without dimensions, and seeing the vast multitude of suns, of milky ways, of stars, and nebulae, all existent in the point.
