5.3 Scientific advancements and religious doubt

Evolutionary Theory

The Victorian era experienced a collision between science and faith that reshaped British culture and literature. Charles Darwin's On the Origin of Species (1859) didn't just propose a new scientific theory; it forced an entire society to reconsider its understanding of humanity's place in the natural world. That tension between discovery and belief runs through much of the literature you'll encounter from this period.

Darwin's Theory of Evolution

Charles Darwin proposed that species evolve over time through natural selection. Organisms with traits better suited to their environment are more likely to survive, reproduce, and pass those traits to their offspring. Over many generations, this process gradually transforms species.

Darwin's theory drew on evidence from multiple scientific fields:

• Geology: Charles Lyell's Principles of Geology (1830–33) had already demonstrated that the Earth was far older than the roughly 6,000 years suggested by a literal reading of Genesis. This vast timescale made gradual evolution plausible.
• Paleontology: Fossil discoveries revealed extinct species and transitional forms between known species, suggesting that life had changed dramatically over time rather than being created in a single, fixed act.

Natural Selection as the Mechanism of Evolution

Natural selection works on variation that already exists within a population. Here's how the process works:

1. Individuals within a species vary in their traits.
2. Some of those traits make certain individuals better suited to their environment.
3. Those individuals are more likely to survive and reproduce.
4. Their offspring inherit the advantageous traits.
5. Over many generations, those traits become more common in the population, and the species gradually changes.

Note that Darwin himself didn't know why organisms varied; the mechanism of genetic inheritance wasn't understood until well after his lifetime. What mattered for Victorian readers was the implication: this process required no divine designer. Species weren't created with a purpose; they were shaped by blind, mechanical forces over immense stretches of time.

Religious Doubt

Crisis of Faith in Victorian Society

Darwin's theory struck at the heart of Victorian religious life. If species evolved through natural selection, the Genesis account of creation couldn't be taken literally. And if humanity descended from earlier primates, the special status of human beings as God's unique creation came into question.

But evolution wasn't the only source of doubt. Higher criticism, a method of scholarly analysis imported largely from German universities, applied the same historical and textual scrutiny to the Bible that scholars used on any ancient text. Researchers questioned who actually wrote the books of the Bible, when they were composed, and whether the events described in them were historically accurate. For many Victorians raised to view Scripture as the unquestioned word of God, this was deeply unsettling. A key flashpoint was Essays and Reviews (1860), a collection by seven Anglican clergymen and scholars that embraced higher criticism and actually generated more controversy in its day than On the Origin of Species.

You can see this crisis reflected in poetry of the period. Tennyson's In Memoriam A.H.H. (completed 1849, before Darwin's major publication) already grapples with a natural world that seems indifferent to human suffering, famously describing nature as "red in tooth and claw." Tennyson was responding in part to earlier geological findings, not to Darwin, which shows that religious doubt was building well before 1859. Matthew Arnold's "Dover Beach" (c. 1851) captures the feeling of faith receding like a tide, leaving only uncertainty behind. Pay attention to how both poets use imagery of the natural world to express spiritual anxiety; that connection between landscape and inner life is a pattern you'll see throughout Victorian literature.

The Rise of Agnosticism and Scientific Materialism

Two intellectual responses to this crisis became especially influential:

• Agnosticism: T.H. Huxley coined this term in 1869 to describe the position that the existence of God can be neither proved nor disproved. Agnostics didn't necessarily reject religion outright, but they insisted that honest inquiry meant admitting the limits of human knowledge. Huxley, one of Darwin's most vocal public defenders (often called "Darwin's Bulldog"), became the movement's most prominent figure.
• Scientific materialism: This worldview held that the physical, material world is the only reality and that everything, including human consciousness and morality, can ultimately be explained through scientific inquiry. Proponents argued that religious explanations were unnecessary and that science alone could provide a reliable account of the world.

Both positions challenged religion's traditional authority in Victorian society. Religion had long provided not just spiritual comfort but also the foundation for moral codes, social order, and explanations of the natural world. As science offered competing answers, many Victorians found themselves caught between inherited faith and new knowledge. That tension produced some of the most powerful and searching literature of the century.
