'Intimacy seems to me to be a moment of being with another and enjoying it; loneliness seems like a moment of being separated from others when I would like to be with them. Hostility and alienation seem like moments of being against others and in some way enjoying it, or of experiencing others being against me and not enjoying it. Loneliness and intimacy seem like unavoidable moments of life for normal people. Hostility and alienation seem like unnatural human experiences, even though we might experience them often in our lives.'
Keith Clark, An Experience of Celibacy: A creative reflection on intimacy, loneliness, sexuality and commitment, p.20.
