When you wonder about the mystery of yourself, look to Christ, who gives you the meaning of life. When you wonder what it means to be a mature person, look to Christ, who is the fulfillness of humanity. And when you wonder about your role in the future of the world look to Christ.

The stakes are immense, the task colossal, the time is short. But we may hope — we must hope — that man’s own creation, man’s own genius, will not destroy him. Scholars, indeed all men, must move forward in the faith of that philosopher who held that there is no problem the human reason can propound which the human reason cannot reason out.

Everything that the human race has done and thought is concerned with the satisfaction of deeply felt needs and the assuagement of pain. One has to keep this constantly in mind if one wishes to understand spiritual movements and their development. Feeling and longing are the motive force behind all human endeavor and human creation, in however exalted a guise the latter may present themselves to us.

The end of the human race will be that it will eventually die of civilization.

Humanity is not yet sufficiently advanced to be willingly led by the discover's keen searching sense. But who knows? Perhaps it is better in this present world of ours that a revolutionary idea or invention instead of being helped and patted, be hampered and ill-treated in its adolescence — by want of means, by selfish interest, pedantry, stupidity and ignorance; that it be attacked and stifled; that it pass through bitter trials and tribulations, through the heartless strife of commercial existence. So do we get our light. So all that was great in the past was ridiculed, condemned, combated, suppressed — only to emerge all the more powerfully, all the more triumphantly from the struggle.

As our own species is in the process of proving, one cannot have superior science and inferior morals. The combination is unstable and self-destroying.

If there ever was in the history of humanity an enemy who was truly universal, an enemy whose acts and moves trouble the entire world, threaten the entire world, attack the entire world in any way or another, that real and really universal enemy is precisely Yankee imperialism.

War is a defeat for humanity.

I've been put on this planet to protect wildlife and wildnerness areas, which in essence is gonna help humanity. I want to have the purest oceans, I want to be able to drink water straight outta that creek, I want to stop the ozone layer [from depleting], I want to save the world.

Benevolence is the characteristic element of humanity.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It's been said that astronomy is a humbling, and, I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known.

There is something within me that might be illusion as it is often case with young delighted people, but if I would be fortunate to achieve some of my ideals, it would be on the behalf of the whole of humanity. Address at the Belgrade train station (1 June 1892)

A really great man is known by three signs— generosity in the design, humanity in the execution, moderation in success.

War should belong to the tragic past, to history: it should find no place on humanity's agenda for the future.

Humanity should question itself, once more, about the absurd and always unfair phenomenon of war, on whose stage of death and pain only remain standing the negotiating table that could and should have prevented it.

We are now standing in the face of the greatest historical confrontation humanity has ever experienced. I do not think the wide circle of the American Society, or the wide circle of the Christian Community realise this fully. We are now facing the final confrontation between the Church and the antichurch, between the Gospel and the antigospel, between Christ and the antichrist. This confrontation lies within the plans of Divine Providence. It is, therefore, in God's Plan, and it must be a trial which the Church must take up, and face courageously. From his farewell address in 1976, when as Cardinal of Krakow he attended the Eucharistic Congress in Philadelphia.

Science fiction. You're right, it's crazy. In fact, it's even worse than that, it's nuts. You wanna hear something really nutty? I heard of a couple guys who wanna build something called an airplane, you know you get people to go in, and fly around like birds, it's ridiculous, right? And what about breaking the sound barrier, or rockets to the moon? Atomic energy, or a mission to Mars? Science fiction, right? Look, all I'm asking is for you to just have the tiniest bit of vision. You know, to just sit back for one minute and look at the big picture. To take a chance on something that just might end up being the most profoundly impactful moment for humanity, for the history… of history.

Human history can be viewed as a slowly dawning awareness that we are members of a larger group. Initially our loyalties were to ourselves and our immediate family, next, to bands of wandering hunter-gatherers, then to tribes, small settlements, city-states, nations. We have broadened the circle of those we love. [...] If we are to survive, our loyalties must be broadened further, to include the whole human community, the entire planet Earth. Many of those who run the nations will find this idea unpleasant. They will fear the loss of power. We will hear much about treason and disloyalty. Rich nation-states will have to share their wealth with poor ones. But the choice, as H. G. Wells once said in a different context, is clearly the universe or nothing.

[...] and he turned to the fool and said with amazement, “How could you find that which my brightest and bravest could not?”

And the fool replied, “I don’t know. I only knew that you were thirsty.”

The story of the Fisher King

The open society, the unrestricted access to knowledge, the unplanned and uninhibited association of men for its furtherance - these are what may make a vast, complex, ever growing, ever changing, ever more specialized and expert technological world, nevertheless a world of human community.

The victory of democracy in South Africa is the common achievement of all humanity.

Once we overcome our fear of being tiny, we find ourselves on the threshold of a vast and awesome Universe that utterly dwarfs — in time, in space, and in potential — the tidy anthropocentric proscenium of our ancestors.

The choice is with us still, but the civilization now in jeopardy is all humanity. As the ancient myth makers knew, we are children equally of the earth and the sky. In our tenure of this planet we've accumulated dangerous evolutionary baggage — propensities for aggression and ritual, submission to leaders, hostility to outsiders — all of which puts our survival in some doubt. But we've also acquired compassion for others, love for our children and desire to learn from history and experience, and a great soaring passionate intelligence — the clear tools for our continued survival and prosperity. Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the cosmos, an inescapable perspective awaits.

What is tolerance? It is the consequence of humanity. We are all formed of frailty and error; let us pardon reciprocally each other's folly — that is the first law of nature.

Faith in a holy cause is to a considerable extent a substitute for the lost faith in ourselves.
