"Now here's my secret", said the fox, "it is very simple. It is only with ones heart that one can see clearly. What is essential is invisible to the eye."
("The Little Prince" by Antoine de Saint-Exupery)
"The soul would have no rainbow, if the eye had no tears." (Native American Proverb)
"True conformity to the dictates of nature requires reverence for the past and solicitude for the future. 'Nature' is not simply the sensation of the passing moment; it is eternal, though we evanescent men experience only a fragment of it. We have no right to imperil the happiness of posterity by impudently tinkering with the heritage of humanity."
"Every right is married to a duty, every freedom owns a corresponding responsibility. There cannot be genuine freedom unless there exists also genuine order in the moral realm and in the social realm."
