From the book, The Eternal Now, sermons of Paul Tillich written for college aged young people: “Our lanugage has wisely sensed two sides of man’s being alone. It has created the word “loneliness” to express the pain of being alone. And it has created the word “solitude” to express the glory of being alone.”
On the latter, he writes:
“Sometimes God thrusts us out of the crowd into a solitude we did not desire, but which nonethless takes hold of us. The prophet Jeremiah says–‘I sit alone, because thy hand was upon me.’ God sometimes lays hands upon us. He wants us to ask the question of truth that may isolate us from most men, and that can be asked only in solitude. He wants us to ask the question of justice that may bring us suffering and death, and that can grow in us only in solitude. He wants us to break through the ordinary ways of man that may bring disrepute and hatred upon us, a breakthrough that can happen only in solitude. He wants us to penetrate to the boundaries of our being, where the mystery of life appears, and it can only appear in moments of solitude.”
Sounds true to me!
