"Sit down in climbing, and hear the pines sing."

“None of Nature's landscapes are ugly so long as they are wild.”

“Man has injured every animal he has touched.”

“When night was drawing near, I ran down the flowery slopes exhilarated, thanking God for the gift of this great day. The setting sun fired the clouds. All the world seemed new-born. Every thing, even the commonest, was seen in new light and was looked at with new interest as if never seen before.”

“All the wild world is beautiful, and it matters but little where we go, to highlands or lowlands, woods or plains, on the sea or land or down among the crystals of waves or high in a balloon in the sky; through all the climates, hot or cold, storms and calms, everywhere and always we are in God's eternal beauty and love. So universally true is this, the spot where we chance to be always seems the best.”

“The sun shines not on us but in us. The rivers flow not past, but through us, thrilling, tingling, vibrating every fiber and cell of the substance of our bodies, making them glide and sing. The trees wave and the flowers bloom in our bodies as well as our souls, and every bird song, wind song, and tremendous storm song of the rocks in the heart of the mountains is our song, our very own, and sings our love.”

“Why should man value himself as more than a small part of the one great unit of creation? And what creature of all that the Lord has taken the pains to make is not essential to the completeness of that unit — the cosmos? The universe would be incomplete without man; but it would also be incomplete without the smallest transmicroscopic creature that dwells beyond our conceitful eyes and knowledge. From the dust of the earth, from the common elementary fund, the Creator has made Homo sapiens. From the same material he has made every other creature, however noxious and insignificant to us. They are earth-born companions and our fellow mortals. … This star, our own good earth, made many a successful journey around the heavens ere man was made, and whole kingdoms of creatures enjoyed existence and returned to dust ere man appeared to claim them. After human beings have also played their part in Creation's plan, they too may disappear without any general burning or extraordinary commotion whatever.”
