What's Covered

This tutorial will will cover the topic of Social Darwinism, through the definition and discussion of:

  1. Charles Darwin
  2. Herbert Spencer and Social Darwinism


Social Darwinism begins with the work of Charles Darwin and his ideas of evolution and natural selection, ideas that were later co-opted and applied to society.

It’s important to note that these ideas have been mostly discredited in academia in sociology. Sociologists don't call themselves Social Darwinists. Despite this, these ideas are a very important part of Western thought.

Charles Darwin spent a lot of time in South America and the Galapagos Islands. He argued that evolution in animals happens because of natural selection. Random genetic mutations occur within individuals that give them an advantage over other members of the species; these mutated individuals are therefore more likely to reproduce and pass on their genes.


A bird eats termites by fishing them out of a tree where they live. It is advantageous, then, for the bird to have a longer beak. Every bird in the species has a beak that's about two inches long. One day, a bird in the species is born with a beak that is 2 and 1/4 inches long. This allows it to more easily access the termites. He is going to be more successful than anybody else in the species.

It follows, then, that he's going to eat more and will be more likely to reproduce and pass on those genes to his offspring, who themselves may have longer beaks. In this way, over many millennia, genes like this get spread about the population and eventually all the birds have beaks that are that length.

This is how the theory of natural selection works. The bird with the longer beak was selected because it had a mutation that was advantageous. This mutation allowed it to outrival other birds.

Did You Know

Darwin studied finches and their beak shapes on the Galapagos Islands to help develop this theory.


Herbert Spencer (1820-1903) was an English philosopher, a mathematician, and a natural and a social scientist; he wore many hats in his career, as many of the early thinkers did. A contemporary of Darwin, Spencer took Darwin’s theories, particularly natural selection and competition, and applied them to society, formulating the idea of Social Darwinism.

Spencer called evolutionary competition ‘survival of the fittest’. He thought that the same kind of competition that occurs in nature also happens in society. Spencer argued that societies pass through a process of natural selection, and only the most fit societies will win the competition and advance.

Terms to Know

Herbert Spencer

A 19th century thinker who gave us the idea of "survival of the fittest" and applied Darwin's theory of natural selection to society.

Social Darwinism

A theory of society that views society, like nature, to be a survival of the fittest.

Did You Know

Many people think that Darwin gave us the adage ‘survival of the fittest,’ but it was actually Herbert Spencer who coined the term. However, it’s acceptable to associate the two, because it fits Darwin's theories fairly well.


At the time Spencer was doing his theorizing, explorers had begun to discover, research, and catalog tribal societies from all over the world. For the first time in European history, people like Spencer--Englishmen and Europeans--became aware of the startling array of diversity of human life all over the globe.

Compared to these tribal societies, Englishmen like Spencer felt that their own societies were more evolved, more refined. They had already passed through the stages that the primitive societies were currently in.

Given this diversity of human life all over the globe, Spencer felt assured in his belief that societies progress from simplicity towards complexity, similar to Darwin’s argument that the natural organism passes from simplicity to complexity. They thought that this was a law--a rule-bound way that societies will develop. Societies will compete and progress or they will falter.

The idea of the progress of social evolution was extremely influential among Europeans in the late 19th and early 20th centuries, although today it is widely discredited. At that time, though, the scientific community was obsessed with discovering laws of society that would cause society to evolve and progress towards a more harmonious state.

Spencer maintained that more simple forms of social organization were outcompeted and eliminated. This way of thinking has completely fallen out of fashion because it's easy to see how dangerous it can be for a society.

ExampleHitler was motivated by this line of thinking when he advanced the idea that we could develop an Aryan race that was somehow better or more progressed than the rest of society.


Today you learned about the ideas of Charles Darwin, Herbert Spencer and Social Darwinism. Social Darwinism was an important part of the history of Western thought, which is why you study it, but it has since been widely discredited and today only the extreme fringes would subscribe to its tenets.
