"Language... 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."

"Our language has wisely sensed the two sides of 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."

"Loneliness expresses the pain of being alone and solitude expresses the glory of being alone."

"Man's ultimate concern must be expressed symbolically, because symbolic language alone is able to express the ultimate."

"The courage to be is the courage to accept oneself, in spite of being unacceptable."

"Decision is a risk rooted in the courage of being free."
