'Life has its moments of loneliness. Sometimes we experience them in a crowd; sometimes when all alone. Sometimes those moments are deliberately chosen; sometimes they seem forced upon us. Loneliness can become unhealthy and even neurotic if it is not entered into in a healthy way, or if it aggravated by fear, guilt, anxiety, depression, alienation, self-doubt or hostility. But in and of itself, loneliness is simply one of life's moments.'
Keith Clark, An Experience of Celibacy, p.27.
