By an Evolutionist

by Alfred Tennyson

(Poem, Summary, Paraphrase & Analysis) 

By an Evolutionist

The Lord let the house of a brute to the soul of a man,

And the man said, “Am I your debtor?”

And the Lord—“Not yet: but make it as clean as you can,                         

And then I will let you a better.”

 

I.

This is the end of the animal life,

Man is arisen, a reasoning soul!

For I have seen in their anger and strife

The driving of the will,

And the passion that works thro’ the beast,

Which, conscious, would fain control

The works of the foolish will,

And give to the good release,

And add to the evil, woe.

 

II.

But I am a man, and the will of man

Is the will of God, and is strong—

And man is the measure of all,

And things are as they seem to be,

And the voice of man is the voice of God,

And the soul of man is free.

 

III.

For what are men better than sheep or goats

That nourish a blind life within the brain,

If, knowing God, they lift not hands of prayer

Both for themselves and those who call them friend?

 

IV.

For I count it nobler to serve,

And to be ruled by Love,

Than to rule and to reign in pride,

And to fall from a height above;

And the beast that is dead and gone

Would have scorn’d his shuddering soul,

Could he see what he once was—Man,

The Lord of the earth and the sea,

And the stars in their courses roll.

 

V.

I have climb’d to the snows of Age,

And I gaze at a field in the Past,

Where I sank with the body at times,

And the soul by the body was bound,

And the end of my journey seems near,

At the top of the last long hill;

But the Lord of the Sun, the Spirit of God,

Is with me, still and still.

 

VI.

Thro’ the ages I pass, and the dying is life,

And the living is death, and I know

That the earth is a mother of souls,

And the dust of the dust is the whole,

And I die in her bosom below,

And I rise on her bosom above.

 

VII.

I have climb’d from the worm to the man,

From the man to the Lord of Love;

And the Lord of Love, as He loves,

Will raise me to what I shall be,

To the Spirit divine of a man,

That hath conquered and reigns above,

And the Lord of Love is God,

And the man is one with Him.

 

Summary

Once, in the deep dawn of existence, the Lord rented out a humble dwelling — the body of a brute — to a soul newly awakened.

The Lord said, almost with a smile, “Make this house as clean as you can, and one day I will let you a better one.”

Thus began the soul’s long pilgrimage — the great adventure of rising from the beast to the man.

At first, the soul lived in the shadowed house of instinct, caught in the struggle of appetite and survival.

It watched the wild passions of the creatures around it — their hunger, their anger, their will — and slowly felt within itself a faint, rising light.

There was something more than instinct here — a stirring of reason, of conscience, of choice.

The brute was giving birth to the man.

And when at last the soul stood upright and spoke, it said with wonder:

“Now I am man — a reasoning soul!

The will within me is not blind; it is strong, it is divine.

The voice that speaks in me is the voice of God Himself.”

For in that awakening came a new pride — the pride of reason, the belief that man was the measure of all things.

Yet as the years passed, man learned another truth.

He saw that knowledge and mastery alone were not greatness.

He looked upon the beasts again and thought,

“What am I better than they, if I do not lift my hands in prayer?

If I do not serve love, or remember mercy?”

And so, the proud ruler became a humble servant — for he saw that to serve in love is nobler than to rule in pride.

Then came old age — the long climb to the snows.

The soul, weary yet peaceful, looked back at the valleys below where once it struggled and fell.

It saw how the body had often chained the spirit, and how, even so, the spirit had learned to rise.

And though the final summit loomed — the hill of death — the soul no longer feared it, for it knew that the Spirit of God, the Lord of the Sun, journeyed with it still.

Now the soul understood the mystery of life and death:

That dying is but another kind of living,

That the earth itself is a mother of souls — giving birth, receiving, and giving birth again.

In her bosom, the soul dies and rises endlessly, part of the eternal rhythm of creation.

And finally, standing at the edge of time, the soul speaks one last time:

“I have climbed from the worm to the man, and from the man to the Lord of Love.

And He who loves will lift me higher still — to that divine spirit which conquers and reigns in union with God.”

Thus ends the great journey.

From brute to man, from man to love, from love to God —

the soul has come home.

 

Paraphrase

God allowed a human soul to live for a time inside the body of an animal.

The soul asked, “Do I owe You anything for this?”

God replied, “Not yet — but if you make this place as pure and good as you can, I will give you a better one later.”

So began the soul’s journey upward — from brute to human, from human to divine.

 

I.

The animal life has reached its end — man has appeared, a being capable of reason.

In the struggles and passions of animals, the soul has glimpsed a faint reflection of what would later become the human will — a desire to control instincts, to choose good over evil.

The creature strives, suffers, and grows toward self-awareness.

 

II.

Now man stands apart, conscious and strong.

He believes that his will reflects the will of God Himself.

He feels certain that human reason is the true measure of all things — that the world is as it seems to human perception, that the human voice speaks with divine authority, and that the soul of man is free.

 

III.

But then comes a humbler realization:

What makes men any better than beasts if they live blindly, feeding only their minds and bodies, without lifting their hearts in prayer?

If they do not seek God — for themselves and for their friends — their so-called reason is wasted.

 

IV.

Man comes to see that true greatness lies not in ruling or pride, but in loving and serving.

It is nobler to obey the law of love than to dominate in arrogance.

If the animal could look upon the human who misuses his gift of reason, it would pity him — for the beast, in its simple way, never fell so far as man can fall.

The creature once looked up to man as “Lord of the Earth and Sea,” ruler even of the stars — but man’s pride can bring him lower than the beast he rose from.

 

V.

Now old age approaches.

The speaker feels as though he has climbed a long mountain, nearing the summit of life.

He looks back on the earlier stages of his journey — the physical desires that once bound the spirit — and knows that the end is near.

Yet he takes comfort, for the Spirit of God, the “Lord of the Sun,” still walks beside him.

 

VI.

He realizes that through all the ages, dying and living have been one continuous process — each death leading to new life.

The earth is like a mother, giving birth to souls from her dust and receiving them back again.

In her embrace, life and death are part of the same eternal movement.

 

VII.

Finally, the speaker looks back on his evolution — from worm to man — and ahead to his final transformation:

from man to the “Lord of Love.”

And this Lord of Love — God Himself — will raise him to the divine spirit that conquers and reigns above.

In that final union, man and God become one in love.

 

Summary of the Meaning

The poem traces the spiritual ascent of humanity — from animal instincts to human reason, from human pride to humble love, and finally to union with the divine.

It is Tennyson’s vision of evolution not just as a biological process, but as a moral and spiritual journey: the soul’s slow return to God.

 

Analysis in Detail

Alfred, Lord Tennyson’s “By an Evolutionist” is one of his most profound meditations on the unity of science and faith, life and death, matter and spirit. Written in the late nineteenth century, when Darwin’s theory of evolution had stirred both excitement and anxiety, Tennyson’s poem offers not a scientific argument but a spiritual interpretation of evolution — the gradual unfolding of divine purpose within creation. Through the voice of a reflective speaker, he transforms biological evolution into a moral and spiritual ascent: from brute instinct to human consciousness, and from human pride to divine love.

 

The Parable of the Soul’s House

The opening stanza presents a striking parable: God lets “the house of a brute” — the animal body — to the “soul of a man.” The Lord tells the tenant, “Make it as clean as you can, and then I will let you a better.” This allegory sets the tone for the entire poem. The human soul, newly awakened, inherits its body from its animal ancestry. Yet, this is not presented as degradation but as responsibility. Man’s duty is to purify, refine, and spiritualize what he has received — to make the “house” worthy of a higher dwelling. The transaction between God and the soul thus becomes a metaphor for evolution as divine stewardship: progress is not merely biological but moral.

 

From Instinct to Reason

In the first section, the speaker declares that “This is the end of the animal life, / Man is arisen, a reasoning soul.” Here Tennyson envisions humanity as the culmination of a long chain of striving — not a sudden creation but a transformation of energy and will that already existed within the beast. He sees in animal “anger and strife” the seeds of human will — the same power that, once conscious, seeks moral control. The phrase “the driving of the will” suggests a continuous line of force running from animal instinct to human purpose. Evolution, then, is not a random struggle but the gradual awakening of mind and spirit.

 

Man’s Faith in His Own Freedom

In the second section, man asserts his new identity with bold confidence. He proclaims that the human will is one with the will of God, that man is “the measure of all,” and that his soul is free. This declaration echoes the rational humanism of the Enlightenment — the belief that reason and consciousness make man sovereign in the natural order. For Tennyson’s speaker, this is an essential stage in human development: the realization of freedom and divine likeness. Yet beneath this tone of triumph, there is a subtle irony. Tennyson knows that self-reliance can turn to arrogance, that man’s pride in his reason can become his next spiritual test.

 

The Moral Awakening: Beyond Pride

In the third and fourth sections, a note of humility replaces the earlier triumph. The speaker begins to question: “What are men better than sheep or goats / That nourish a blind life within the brain, / If, knowing God, they lift not hands of prayer?” The thought recalls Tennyson’s own religious anxiety — his conviction that intellect alone cannot satisfy the soul. If man’s reason does not lead to reverence and love, then he is no better than the beasts he transcended. The poem thus shifts from evolution as progress in knowledge to evolution as progress in love and moral awareness. To serve and to love, the poet insists, is nobler than to rule in pride. Man’s true elevation lies not in domination but in self-surrender.

Here Tennyson contrasts the proud man with the innocent beast. The irony deepens: the “beast that is dead and gone” might pity the fallen man who misuses his reason. Having risen to moral awareness, humanity also bears the potential for moral fall. The higher the ascent, the deeper the fall — a theme that resonates with Tennyson’s Christian understanding of sin and redemption.

 

The Ascent of Age and Wisdom

In the fifth section, the speaker has reached old age — “the snows of Age” — and looks back on his life as a long climb up a mountain. The image of ascent mirrors both evolutionary progress and spiritual pilgrimage. From this height, he can see the valleys of earlier struggle where “the body at times” bound “the soul.” Yet he now feels the presence of “the Lord of the Sun, the Spirit of God,” guiding him even as he approaches death. This stage represents the culmination of human consciousness — not pride in intellect, but peace in faith. The climb, long and laborious, ends not in exhaustion but in illumination.

 

The Mystery of Life and Death

The sixth section reflects Tennyson’s lifelong meditation on mortality. The poet declares that “the dying is life, / And the living is death,” recognizing that existence is an endless rhythm of transformation. Death is not an end but a passage through which the soul continues to evolve. The earth itself becomes a maternal figure — “the mother of souls” — who receives the dead and gives them new life. Here, evolution expands beyond biology into a cosmic cycle: birth, decay, and renewal are woven into the divine order. The poem transforms the scientific notion of natural recycling into a sacred mystery of resurrection.

 

Union with Divine Love

In the final section, the speaker affirms the ultimate goal of evolution: union with the “Lord of Love.” He traces his long ascent — “from the worm to the man, / From the man to the Lord of Love” — and anticipates another transformation, from human to divine. This closing vision elevates the material process of evolution into a spiritual revelation. Love becomes the final law of the universe — the divine energy that drives all progress. The soul, once a tenant in a brute’s body, will now share the nature of its Creator. The poem ends in harmony, not conflict: man and God are reconciled, science and faith united, time and eternity joined in love.

 

Themes and Vision

Tennyson’s “By an Evolutionist” is deeply theological in its intent but modern in its framework. The poet does not deny Darwin’s theory; instead, he baptizes it with spiritual meaning. Evolution, for him, is not a godless mechanism but a divine method. Through the slow struggle of nature, God brings forth consciousness, morality, and love. The poem traces three great movements: biological growth (from beast to man), moral awakening (from pride to humility), and spiritual union (from man to God). Each stage is both scientific and symbolic, showing that physical evolution mirrors the evolution of the soul.

 

Tone and Style

Tennyson’s tone throughout is reverent yet reflective. The poem reads almost like a sermon delivered by a soul at the end of its pilgrimage — part confession, part prophecy. His language moves from firm assertion to gentle wisdom, mirroring the human journey from confidence to surrender. The diction blends religious imagery (“Lord of the Sun,” “Spirit of God”) with natural and evolutionary motifs (“worm,” “beast,” “man”), binding the scientific and the sacred into one continuous vision.

 

Conclusion

In “By an Evolutionist,” Tennyson turns the controversial concept of evolution into a hymn of faith. For him, evolution does not dethrone God; it reveals the divine purpose woven through matter and time. The poem’s message is one of hope: that the soul, though born in dust, is destined for divinity. It will rise — step by step, age by age — until it becomes one with the Lord of Love who called it into being.

Thus, “By an Evolutionist” stands not as a denial of science but as Tennyson’s poetic reconciliation of faith and progress, body and soul, creation and Creator.
