The basic understanding of evolution that I carry around in my head enhances my life. I've done night dives in the Caribbean, 130 feet down, and there were moments when I might have felt like an astronaut visiting some alien planet filled with exotic life. But I knew better. I was home and all the weird and wonderful lifeforms around me were family. The magnificence and importance of nature are clarified and amplified in light of the awareness of shared ancestors and a common origin. I understand that I'm inside the big beautiful blur of life that surrounds our world. And that makes the ride even more amazing.

There will be, I think, an attempt to grasp again the surprise and accidents of nature and a more intimate and sympathetic study of its moods, together with a renewed wonder and humility on the part of such as are still capable of these basic reactions.

In its encounter with Nature, science invariably elicits a sense of reverence and awe. The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos. And the cumulative worldwide build-up of knowledge over time converts science into something only a little short of a trans-national, trans-generational meta-mind.

They remind us that humans have evolved to wonder, that understanding is a joy, that knowledge is prerequisite to survival. I believe our future depends on how well we know this Cosmos in which we float like a mote of dust in the morning sky.

Every aspect of Nature reveals a deep mystery and touches our sense of wonder and awe. Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.

The cosmos is interesting rather than perfect, and everything is not part of some greater plan, nor is all necessarily under control. Understanding this keeps us humble, able to admit that we cannot know or define.

The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home. In a cosmic perspective, most human concerns seem insignificant, even petty. And yet our species is young and curious and brave and shows much promise. In the last few millennia we have made the most astonishing and unexpected discoveries about the Cosmos and our place within it, explorations that are exhilarating to consider.

"As a physician, I was trained to deal with uncertainty as aggressively as I dealt with disease itself. The unknown was the enemy. Within this worldview, having a question feels like an emergency; it means that something is out of control and needs to be made known as rapidly, efficiently, and cost-effectively as possible. But death has taken me to the edge of certainty, to the place of questions.

After years of trading mystery for mastery, it was hard and even frightening to stop offering myself reasonable explanations for some of the things that I observed and that others told me, and simply take them as they are. "I don't know" had long been a statement of shame, of personal and professional failing. In all of my training I do not recall hearing it said aloud even once.

But as I listened to more and more people with life-threatening illnesses tell their stories, not knowing simply became a matter of integrity. Things happened. And the explanations I offered myself became increasingly hollow, like a child whistling in the dark. The truth was that very often I didn't know and couldn't explain, and finally, weighed down by the many, many instances of the mysterious which are such an integral part of illness and healing, I surrendered. It was a moment of awakening.

For the first time, I became curious about the things I had been unwilling to see before, more sensitive to inconsistencies I had glibly explained or successfully ignored, more willing to ask people questions and draw them out about stories I would have otherwise dismissed. What I have found in the end was that the life I had defended as a doctor as precious was also Holy.

I no longer feel that life is ordinary. Everyday life is filled with mystery. The things we know are only a small part of the things we cannot know but can only glimpse. Yet even the smallest of glimpses can sustain us.

Mystery seems to have the power to comfort, to offer hope, and to lend meaning in times of loss and pain. In surpr

It is a great adventure to contemplate the universe, beyond man, to contemplate what it would be like without man, as it was in a great part of its long history and as it is in a great majority of places. When this objective view is finally attained, and the mystery and majesty of matter are fully appreciated, to then turn the objective eye back on man viewed as matter, to view life as part of this universal mystery of greatest depth, is to sense an experience which is very rare, and very exciting. It usually ends in laughter and a delight in the futility of trying to understand what this atom in the universe is, this thing — atoms with curiosity — that looks at itself and wonders why it wonders. Well, these scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man's struggle for good and evil seems inadequate.

I do believe in this evolution of consciousness as the only thing which we can embark on, or in fact, willy-nilly, are embarked on; and along with that will go the spiritual discoveries and, I feel, the inexhaustible wonder that one feels, that opens more and more the more you know. It’s simply that this increasing knowledge constantly enlarges your kingdom and the capacity for admiring and loving the universe.

Does trying to understand the universe at all betray a lack of humility? I believe it is true that humility is the only just response in a confrontation with the universe, but not a humility that prevents us from seeking the nature of the universe we are admiring. If we seek that nature, then love can be informed by truth instead of being based on ignorance or self-deception. If a Creator God exists, would He or She or It or whatever the appropriate pronoun is, prefer a kind of sodden blockhead who worships while understanding nothing? Or would He prefer His votaries to admire the real universe in all its intricacy? I would suggest that science is, at least in part, informed worship.

Death is really the mystery of life, isn't it?

The effort to understand the universe is one of the very few things which lifts human life a little above the level of farce and gives it some of the grace of tragedy.
