These mostly come from Wikiquote, so I can't be certain about their authenticity...but they're good quotes anyway.
"It is only possible to succeed at second-rate pursuits - like becoming a millionaire or a prime minister, winning a war, seducing beautiful women, flying through the stratosphere or landing on the moon. First-rate pursuits - involving, as they must, trying to understand what life is about and trying to convey that understanding - inevitably result in a sense of failure. A Napoleon, a Churchill, a Roosevelt can feel themselves to be successful, but never a Socrates, a Pascal, a Blake. Understanding is for ever unattainable. Therein lies the inevitability of failure in embarking upon its quest, which is none the less the only one worthy of serious attention."
"I wonder whether, in the history of all the civilisations that have ever been, a more insanely optimistic notion has ever been entertained than that you and I, mortal, puny creatures, may yet aspire, with God’s grace and Christ’s help, to be reborn into what St. Paul calls the glorious liberty of the children of God. Or if there was ever a more abysmally pessimistic one than that we, who reach out with our minds and our aspirations to the stars and beyond, should be able so to arrange our lives, so to eat and drink and fornicate and learn and frolic, that our brief span in this world fulfils all our hopes and desires."
"The only ultimate disaster that can befall us, I have come to realize, is to feel ourselves at home here on earth."
"The first thing I remember about the world…is that I was a stranger in it. This feeling, which is at once the glory and desolation of homo sapiens, provides the only thread of consistency that I can detect in my life."
"Animistic savages prostrating themselves before a painted stone have always seemed to me to be nearer the truth than any Einstein or Bertrand Russell."
"There is something ridiculous and even quite indecent in an individual claiming to be happy. Still more a people or a nation making such a claim. The pursuit of happiness…is without any question the most fatuous which could possibly be undertaken. This lamentable phrase 'the pursuit of happiness' is responsible for a good part of the ills and miseries of the modern world."
"We look back on history and what do we see? Empires rising and falling, revolutions and counter-revolutions, wealth accumulating and wealth dispersed, one nation dominant and then another. Shakespeare speaks of 'the rise and fall of great ones that ebb and flow with the moon.'
In one lifetime I have seen my own fellow countrymen ruling over a quarter of the world, the great majority of them convinced, in the words of what is still a favorite song, that, 'God who's made the mighty would make them mightier yet.' I've heard a crazed, cracked Austrian proclaim to the world the establishment of a German Reich that would last a thousand years; an Italian clown announce that he would restart the calendar to begin his own assumption of power. I've heard a murderous Georgian brigand in the Kremlin acclaimed by the intellectual elite of the world as a wiser than Solomon, more enlightened than Ashoka, more humane than Marcus Aurelius. I've seen America wealthier and in terms of weaponry, more powerful than the rest of the world put together, so that Americans, had they so wished, could have outdone an Alexander or a Julius Caesar in the range and scale of their conquests.
All in one little lifetime. All gone with the wind. England part of a tiny island off the coast of Europe, threatened with dismemberment and even bankruptcy. Hitler and Mussolini dead, remembered only in infamy. Stalin a forbidden name in the regime he helped found and dominate for some three decades. America haunted by fears of running out of those precious fluids that keep her motorways roaring, and the smog settling, with troubled memories of a disastrous campaign in Vietnam, and the victories of the Don Quixotes of the media as they charged the windmills of Watergate.
All in one lifetime, all gone. Gone with the wind. Behind the debris of these self-styled, sullen supermen and imperial diplomatists, there stands the gigantic figure of one person, because of whom, by whom, in whom, and through whom alone mankind might still have hope. The person of Jesus Christ."
