Philosopher Quotes on Life

The is key to find a purpose, whatever it truly is that God wills me to do; it's crucial to find a truth which is true to me, to find the idea which I am willing to live and die for.”
What I really need is to get clear about what I must do, not what I must know, except insofar as knowledge must precede every act. What matters is to find a purpose, to see what it really is that God wills that I shall do; the crucial thing is to find a truth which is truth for me, to find the idea for which I am willing to live and die. -

My whole religion is this: do every duty, and expect no reward for it, either here or hereafter.”

“We are like islands in the sea, separate on the surface but connected in the deep.”
Out of my experience, such as it is (and it is limited enough) one fixed conclusion dogmatically emerges, and that is this, that we with our lives are like islands in the sea, or like trees in the forest. The maple and the pine may whisper to each other with their leaves. ... But the trees also commingle their roots in the darkness underground, and the islands also hang together through the ocean' -
“I think that yesterday was a crisis in my life. I finished the first part of Renouvier's second Essais and see no reason why his definition of free will—"the sustaining of a thought because I choose to when I might have other thoughts"—need be the definition of an illusion. At any rate, I will assume for the present—until next year—that it is no illusion. My first act of free will shall be to believe in free will.”

“To study the meaning of man and of life — I am making significant progress here. I have faith in myself. Man is a mystery: if you spend your entire life trying to puzzle it out, then do not say that you have wasted your time. I occupy myself with this mystery, because I want to be a man.”

“Princess, my little Princess, Oh, how wonderful it will be! I am coming with money and staying a long time and bringing something beautiful for you and then go on to Paris and become a great scholar and then come back to Vienna with a huge, enormous halo, and then we will soon get married, and I will cure all the incurable nervous cases and through you I shall be healthy and I will go on kissing you till you are strong and gay and happy — and "if they haven't died, they are still alive today.”

“A man like me cannot live without a hobby-horse, a consuming passion — in Schiller 's words a tyrant. I have found my tyrant, and in his service I know no limits. My tyrant is psychology. it has always been my distant, beckoning goal and now since I have hit upon the neuroses, it has come so much the nearer.”
Ein Mensch wie ich kann ohne Steckenpferd, ohne herrschende Leidenschaften, ohne einen Tyrannen in Schillers Worten, nicht leben.

Gabriel Marcel on Life
-
“Life in a world centred on function is liable to dispair because in reality the world is empty, it rings hollow; and if it resist this temptation it is only to the extent that there comes into plat from within it and in its favour certain hidden forces which are beyond its power to conceive or to recognise.”
Wikiquote -

“I am I and my circumstance, and if I do not save it, I do not save myself.”
Yo soy yo y mi circumstancia, y si no la salvo a ella no me salvo yo. -
“Life cannot wait until the sciences may have explained the universe scientifically. We cannot put off living until we are ready. The most salient characteristic of life is its coerciveness: it is always urgent, "here and now" without any possible postponement. Life is fired at us point-blank. And culture, which is but its interpretation, cannot wait any more than can life itself.”
Original: " La vida no puede esperar a que las ciencias expliquen científicamente el Universo . No se puede vivir ad kalendas graecas . El atributo más esencial de la existencia es su perentoriedad: la vida es siempre urgente. Se vive aquí y ahora sin posible demora ni traspaso. La vida nos es disparada a quemarropa. Ya la cultura, que no es sino su interpretación, no puede tampoco esperar. | Miss -
“Life is fired at us point blank.”
More context: "To live or to be alive or, what is the same thing, to be a man, does not admit of any preparations or preliminary experiments. Life is fired at us point blank. ... Where and when we are born, or happen to find ourselves after we were born, there and then, like it or not, we must sink or swim. | Man and People [ El hombre y la gente ] (1957), p. 42, translated by Willard R. Trask. IS -

“Civilization is, before all else, the will to live in common.”
Pierre Hadot on Life
-
“Ancient philosophy proposed to mankind an art of living.”
trans. Michael Chase, p. 272 -
“Incommensurable; but also inseparable. No discourse worthy of being called philosophical, that is separated from the philosophical life; no philosophical life, if it is not strictly linked to philosophical discourse. It is there that the danger inherent to a philosophical life resides: the ambiguity of philosophical discourse.”
Incommensurables donc, mais aussi inséparables. Pas de discours qui mérite d’être appelé philosophique, s’il est séparé de la vie philosophique, pas de vie philosophique, si elle n’est étroitement liée au discours philosophique. C’est là d’ailleurs que réside le danger inhérent à la vie philosophique: l’ambiguïté du discours philosophique. -
“If these experiences [of union with the Absolute] are rare, nonetheless they lend their fundamental tonality to the Plotinian way of life, for that way of life appears to us now as a waiting for the unforseeable surging-forth of these privileged moments which give their full sense to life”
Si ces expériences sont rares, elles n’en donnent pas moins sa tonalité fondamentale au mode de vie plotinien, puisque celui-ci nous apparaît maintenant comme l’attente du surgissement imprévisible de ces moments privilégiés qui donnent tout leur sens à la vie. -

“The Examined Life (1989)”
When I was 15 years old, or 16, I carried around on the streets of Brooklyn a paperback copy of Plato 's Republic , front cover facing outward. I had read only some of it and understood less, but I was excited by it and knew it was something wonderful. -
“Our principles fix what our life stands for, our aims create the light our life is bathed in, and our rationality, both individual and coordinate, defines and symbolizes the distance we have come from mere animality. It is by these means that our lives come to more than what they instrumentally yield. And by meaning more, our lives yield more.”

Public Addresses -
“And may I ask you, Europeans, what country you have ever raised to better conditions? Wherever you have found weaker races, you have exterminated them by the roots, as it were. You have settled on their lands and they are gone forever. What is the history of your America, your Australia and New Zealand, your Pacific Islands and South Africa? Where are those aboriginal races there today? They are all exterminated, you have killed them outright, as if they were wild beasts. It is only where you have not the power to do so, and there only, that other nations are still alive.”

“The Meaning of Jewish Existence" in The Torch (1950)”
The time for the kingdom may be far off, but the task is plain: to retain our share in God in spite of peril and contempt. There is a war to wage against the vulgar, the glorification of the absurd , a war that is incessant, universal. Loyal to the presence of the ultimate in the common, we may be able to make it clear that man is more than man, that in doing the finite he may perceive the infinit -
“Man Is Not Alone : A Philosophy Of Religion (1951), Ch. 24 : The Great Yearning; The Yearning for Spiritual Living”
He who is satisfied has never truly craved, and he who craves for the light of God neglects his ease for ardor, his life for love , knowing that contentment is the shadow not the light . The great yearning that sweeps eternity is a yearning to praise, a yearning to serve. And when the waves of that yearning swell in our souls all the barriers are pushed aside: the crust of callousness, the hysteri -
“The greatest problem is not how to continue but how to exalt our existence. The call for a life beyond the grave is presumptuous, if there is no cry for eternal life prior to our descending to the grave. Eternity is not perpetual future but perpetual presence. He has planted in us the seed of eternal life. The world to come is not only a hereafter but also a here-now .”

“We do not step out of the world when we pray; we merely see the world in a different setting. The self is not the hub but the spoke of the revolving wheel. It is precisely the function of prayer to shift the center of living from self-consciousness to self-surrender.”
Man's Quest For God : Studies In Prayer And Symbolism (1954), p. 7; Heschel would later use this analogy in several minor variations in other writings.
