John Muir

"How glorious a greeting the sun gives the mountains!"

"The power of imagination makes us infinite."

"John Muir, Earth — planet, Universe[Muir's home address, as inscribed on the inside front cover of his first field journal]"

"The clearest way into the Universe is through a forest wilderness."

"When one tugs at a single thing in nature, he finds it attached to the rest of the world."
