The Hope of Immortality (Ingersoll Lecture, 1906).
“So somehow the "isness" of our present nature is out of harmony with the eternal "oughtness" that forever confronts us. And this simply means this: That within the best of us, there is some evil, and within the worst of us, there is some good. When we come to see this, we take a different attitude toward individuals.”
1950s, Loving Your Enemies (November 1957)
Context: There is something within all of us that causes us to cry out with Ovid, the Latin poet, "I see and approve the better things of life, but the evil things I do." There is something within all of us that causes us to cry out with Plato that the human personality is like a charioteer with two headstrong horses, each wanting to go in different directions. There is something within each of us that causes us to cry out with Goethe, "There is enough stuff in me to make both a gentleman and a rogue." There is something within each of us that causes us to cry out with Apostle Paul, "I see and approve the better things of life, but the evil things I do." So somehow the "isness" of our present nature is out of harmony with the eternal "oughtness" that forever confronts us. And this simply means this: That within the best of us, there is some evil, and within the worst of us, there is some good. When we come to see this, we take a different attitude toward individuals. The person who hates you most has some good in him; even the nation that hates you most has some good in it; even the race that hates you most has some good in it. And when you come to the point that you look in the face of every man and see deep down within him what religion calls "the image of God," you begin to love him in spite of. No matter what he does, you see God’s image there. There is an element of goodness that he can never sluff off. Discover the element of good in your enemy. And as you seek to hate him, find the center of goodness and place your attention there and you will take a new attitude.

We dream of a journey through the universe. But is the universe then not in us? We do not know the depths of our spirit. Inward goes the secret path. Eternity with its worlds, the past and the future, is in us or nowhere.
As translated in "Bildung in Early German Romanticism" by Frederick C. Beiser, in Philosophers on Education : Historical Perspectives (1998) by Amélie Rorty, p. 294
We dream of journeys through the cosmos — Is the cosmos not then in us? We do not know the depths of our own spirit. — The mysterious path leads within. In us, or nowhere, is eternity with its worlds — the past and the future.
Blüthenstaub (1798)
Context: Imagination places the future world for us either above or below or in reincarnation. We dream of travels throughout the universe: is not the universe within us? We do not know the depths of our spirit. The mysterious path leads within. In us, or nowhere, lies eternity with its worlds, the past and the future.
