The poet is in his fortieth year and is "full of life." Yet when generations of the future will read his Leaves, "I that was visible am become invisible." He speaks to these unborn readers who are seeking him, He tells them that perhaps he is with them.
"Full of Life Now" is the last poem of the Calamus group. The poet presents his ideas on the phases of his development from the physical to the spiritual, from the world of manly love to the world of poetry. His past is dark, but his future is bright because he has grown into a poet. His growth as a poet establishes a link between him and his future readers, and he is with them, though apart. He moves away from the seen world to the unseen universe which is the essence of his spiritual life and experience.
