From Leaves of Grass, by Walt Whitman:

Beginning my studies the first step pleas'd me so much,
The mere fact consciousness, these forms, the power of motion,
The least insect or animal, the senses, eyesight, love,
The first step I say awed me and pleas'd me so much,
I have hardly gone and haardly wish'd to go any farther,
But stop and loiter all the time to sing it in ecstatic songs.
