We began yesterday with human worth – the human life experience. That is where we come into the picture but that is not where the whole story begins. The bigger story begins with the emergence of the first protein or even the Big Bang. Digging deeper, we do not know where it begins. We only know parts of our story. So I will begin on the first ordinary day of the year with life because that is what our narrative is about.
Life distinguishes all living things from dirt, rocks, life-giving water and the air we breathe. It is the foundation of all we value in and about the world.
The life process generated, but did not begin with, our spectacular brains. It is the precious and indispensable background for what we call our lives, but it is not the life of Being itself. Life is present in the beating heart, the functioning kidney, the animate limb. It is present in every vital cell of our bodies, yet many cells die every second without our ever noticing. Life is present in our unformed bodies before life becomes experience, and may continue, sometimes for years, after the life experience has ended.
A Humanist ethics respects life, yet distinguishes between life’s mechanics and the Spirit of Being. Life is the vehicle and animating force of soul and spirit, not posited here as separate entities, but as part of the human experience. In describing an “animating force,” I make no pretense of resolving the ongoing debate about what life is, and posit no tangible force, per se; this is only an operating description of the experience we call life.
Life is precious, yet by itself it is without value. Only in the hands of a Being capable of valuing it does it become valuable. We honor it on this first ordinary day of our liturgical year.
Technical and Analytical Readings
What is life? One leading scientist in the field suggests two possible answers, both of which he acknowledges are incomplete: we could say that something is alive if it has certain properties, such as growing and responding to stimuli, or if it evolves by natural selection. [Smith and Szathmáry (see below), pp. 3-4.] Those are among the best definitions we have, but all they tell us is how life functions. They do not seem to tell us what life is, and perhaps we will never know. Because we do not know, we will content ourselves with what we do know.
Our best science suggests that life on Earth first emerged in water from an interaction of inanimate compounds and the natural environment, between 3.5 and 4.0 billion years ago. The story of the origins of life, and our attempts to uncover it, are important parts of our human narrative.
For most non-scientists, this field’s core material alone is quite over our heads. However, even a non-scientist can understand a few basic concepts behind the research. Here are a few of the leading but more accessible works in the field. They tell a fascinating part of the human story, as we set about to uncover who we are and where we came from:

- Sean Carroll, The Big Picture: On the Origins of Life, Meaning, and the Universe Itself (Dutton, 2016): “ . . . Carroll defends what he calls ‘poetic naturalism.’ ‘Naturalism,’ because there is nothing above and beyond nature. In particular, there are no gods or spooks to transcend or interfere with natural laws. So Einstein’s dice are rolling themselves. ‘Poetic,’ because ‘there is more than one way of talking about the world.’”

In the beginning, when God created the heavens and the earth, the earth was a formless wasteland, and darkness covered the abyss . . . Then God said, "Let the earth bring forth vegetation: every kind of plant that bears seed and every kind of fruit tree on earth that bears fruit with its seed in it." [The Bible, Genesis 1:1-2, 11.]
Once when I saw a cripple
Gasping slowly his last days with the white plague,
Looking from hollow eyes, calling for air,
Desperately gesturing with wasted hands
In the dark and dust of a house down in a slum,
I said to myself I would rather have been a tall sunflower
Living in a country garden
Lifting a golden-brown face to the summer,
Rain-washed and dew-misted,
Mixed with the poppies and ranking hollyhocks,
And wonderingly watching night after night
The clear silent processionals of stars.
[Carl Sandburg, "Cripple," from "Chicago Poems" (1916).]
With music strong I come, with my cornets and my drums,
I play not marches for accepted victors only,
I play marches for conquer'd and slain persons.
Have you heard that it was good to gain the day?
I also say it is good to fall, battles are lost in the same spirit in which they are won.
I beat and pound for the dead,
I blow through my embouchures my loudest and gayest for them.
Vivas to those who have fail'd!
And to those whose war-vessels sank in the sea!
And to those themselves who sank in the sea!
And to all generals that lost engagements, and all overcome heroes!
And the numberless unknown heroes equal to the greatest heroes known!
[Walt Whitman, Leaves of Grass, Book III, # 18 (1855).]

Music: Composers, artists, and major works
Several contemporary composers have given us music that sounds like the stirrings of life itself. Most notable, perhaps, is Morton Feldman's String Quartet No. 2 (1983), a five-hour-long minimalist composition that evokes the stirrings of life in a single cell. The work progresses by minute variation, as early life must have done, considering that life did not evolve past the single-celled stage for 500 million years, and complex multi-cellular life took another 2.5 billion years to emerge. This is a long period of time to cover in a single work of music but you may not feel that way if you listen to this String Quartet all at once. If you have the time, it is a rewarding experience – a grand meditation on where we came from. If not, you can get the idea from practically anywhere in the performance. We have recorded performances by Volger Quartett in 1999, Ives Ensemble in 2003 and FLUX Quartet in 2016. A 2002 performance by FLUX Quartet is available on CD.
Other composers have taken up this and related themes, perhaps some intentionally and others not:
- Robert Simpson, Symphony No. 6 (1977): Simpson dedicated the symphony to gynecologist Ian Craft, who had suggested that the emergence of a new form of life from a cell could be paralleled in symphonic form.
- Aaron Jay Kernis, Symphony in Waves (1989): “I think about waves of sound in addition to those of wind and water. Each movement uses some aspect of wave motion: swells and troughs of dynamics, densities, and instrumental color: the ‘sounds’ of light broken into flickering bits by water’s action.”
- Kalevi Aho, Solos for various instruments (1975-2003): these are spare compositions, each for a solo instrument, in minimalist style.
- Aho, Symphony No. 7, "Insect Symphony" (1988) – insects are more complex that one-celled organisms but still are quite primitive, a quality that you can hear in this work.
- John Luther Adams, Everything That Rises: the composer writes: “Time floats and the lines spin out, always rising, in acoustically perfect intervals that grow progressively smaller as they spiral upward…until the music dissolves into the soft noise of the bows, sighing.”
- John Luther Adams, Clusters on a Quadrilateral Grid (1997)
- John Adams, Common Tones in Simple Time (1999): “Part of the piece’s charm lies in the fact that underneath the fast surface movement lies a very slow harmonic movement. . . . The music also concerns itself with registers, both very high and very low. Bass sound is witheld from the entire first part of the piece, making its appearance, when it finally arrives, a genuinely surprising and gratifying event.” (Adams)
- Tan Dun, Dew-Fall-Drops (and here) (2000): “did you see the sound? hear the shape catch the wind can you write it on the sky? the tree wants to rest but the wind never stops” (the composer’s synopsis)
- Christian Wolff, Burdocks (1971), after the plant.
- Wolff, Trio II (1961), similar to Feldman’s String Quartet No 2, for piano, bass and percussion.
- Wolff, Trio III (1996)
- Wolff, Trio IX (2018)
- Luigi Nono, La lontananza nostalgica utopica futura (1989) evokes “the past reflected in the present (nostalgica) brings about a creative utopia (utopica), the desire for what is known becomes a vehicle for what will be possible (futura) through the medium of distance.”
- Scott Wollschleger, String Quartet No. 2, “White Wall” (2014): Wollschleger says that this quartet “represented a break in my own work, or in myself, or in my approach to art, where I wanted to see how you could start from nothing, and pull from within itself something. . . . If you were to drain music from itself, what would be left over?”
- Wollschleger, Brontal Symmety, for piano trio (2015): “Each sound object is revealed and then slowly taken away while new ideas are introduced.”
- Saunders, “Dust” (2018): “The fallible physical body behind the sound, feeling the weight of sound, exploring the essence of a timbre, seeking the grit and noise within.”
- Saunders, “Flesh” (2018): “Each change in the direction of the bellows is closely controlled: the opening of the bellows is accompanied with a fast and regular rhythmic changing of the chin registers, and the closing of the bellows then with the voice.”
- Jiha Park, “The Gleam”: a musical exposition on sunlight, a precursor of life. “She distils light into sound, from the first flicker of morning on the horizon in 'At Dawn' all the way to the moment when full darkness falls again in 'Nightfall Dancer,' capturing the essence of it in notes and silence.”
- Cecil McBee Sextet, “Music from the Source” (1977)
