"It is not easy to write of my good friend, John Muir. The impression of his personality was so strong on those who knew him that all words seem cheap beside it. Those who never knew him can never, through any word of ours, be brought to realize what they have missed. … He had a quaint, crisp way of talking, his literary style in fact, and none of the nature lovers, the men who know how to feel in the presence of great things and beautiful, have expressed their craft better than he."

“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.”

“Sit down in climbing, and hear the pines sing.”

“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.”
