Arthur Schopenhauer - from "On Human Suffering"

“This is the mystery…it reveals to us that all those beings living at the present moment contain within them the actual germ of all which will live in the future, and that these therefore in a certain sense exist already. So that every animal in the full prime of life seems to call to us: ‘Why do you lament the transitoriness of living things? How could I exist if all those of my species which came before me had not died?’

However much the plays and the masks on the world’s stage may change it is always the same people who appear. We sit together and talk and grow excited, and our eyes glitter and our voices grow shriller: just so did others sit and talk a thousand years ago: it was the same thing, and it was the same people: and it will be just so a thousand years hence. The contrivance which prevents us from perceiving this is time.”

John Berger, from "Ways of Seeing"

“If we accept that we can see that hill over there, we propose that from that hill we can be seen.
The reciprocal nature of vision is more fundamental than that of spoken dialogue.
And often dialogue is an attempt to verbalize this—an attempt to explain how, either metaphorically or literally, ‘you see things’, and an attempt to discover how ‘he sees things.’”

Paul Tillich on Courage (From, "The Courage to Be")

“…The aristocratic element in the doctrine of courage was preserved as well as restricted by Aristotle. The motive for withstanding pain and death courageously is, according to him, that it is noble to do so and base not to do so. The courageous man acts ‘for the sake of what is noble, for that is the aim of virtue.’ ‘Noble,’ in these and other passages, is the translation of kalós and “base” is the translation of aischró, words which usually are rendered by ‘beautiful’ and ‘ugly.’ A beautiful or noble deed is a deed to be praised. Courage does what is to be praised and rejects what is to be despised. One praises that in which a being fulfills its potentialities or actualizes its perfections. Courage is the affirmation of one’s essential nature, one’s inner aim or entelechy, but it is an affirmation which has in itself the character of ‘in spite of.’ It includes the possible and, in some cases, the unavoidable sacrifice of elements which also belong to one’s being but which, if not sacrificed, would prevent us from reaching our actual fulfillment. This sacrifice may include pleasure, happiness, even one’s own existence. In any case it is praiseworthy, because in the act of courage the most essential part of our being prevails against the less essential. It is the beauty and goodness of courage that the good and the beautiful are actualized in it. Therefore it is noble.”
