John Muir’s inspiration, joy, and rhapsody while in nature are evident in his experience at a glacier in Alaska:

“Standing here, with facts so fresh and telling and held up so vividly before us, every seeing observer, not to say geologist, must readily apprehend the earth-sculpturing, landscape-making action of flowing ice. And here, too, one learns that the world, though made, is yet being made; that this is still the morning of creation; that mountains long conceived are now being born, channels traced for coming rivers, basins hollowed for lakes” resulting in the making of “mountains and valleys and plains of other predestined landscapes, to be followed by still others in endless rhythm and beauty.”
—John Muir, Travels in Alaska.

J. Philip Newell writes of the teachings of ninth-century Celtic philosopher John Scotus Eriugena. As Newell relates, Eriugena believed that Christ manifests to us not only in scripture but also in creation (34). “Eriugena tells us that God is in all things, the essence of life; God has not created everything out of nothing, but out of his own essence, out of his very life. This is the light that is in all things. . . . The world, therefore, Eriugena regarded as theophany, a visible manifestation of God. . . . To know the Creator, we need only look at the things he has created. The way to learn about God, Eriugena believed, is ‘through the letters of Scripture and through the species of creation’” (35).
