"To few men was it given to realize so completely the element of eternity — of time-effacing enjoyment in work — as it was to John Muir. The secret of it all was in his soul, the soul of a child, of a poet, and of a strong man, all blended into one. … An innate nobility of character, an unstudied reverence for all that is sublime in nature or in life, unconsciously called forth the best in his friends and acquaintances. In the spiritual as in the physical realm flowers blossomed in his footsteps where he went. After all it is to such men as John Muir that we must look for the sustenance of those finer feelings that keep men in touch with the spiritual meaning and beauty of the universe, and make them capable of understanding those rare souls whose insight has invested life with imperishable hope and charm. … To all who knew John Muir intimately his gentleness and humaneness toward all creatures that shared the world with him, was one of the finest attributes of his character. … Among those who have won title to remembrance as prophets and interpreters of nature he rises to a moral as well as poetical altitude that will command the admiring attention of men so long as human records shall endure."

“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.”
