Key Concepts of the Philosophy of John Locke

Read on to learn about John Locke and his empiricist philosophy.

Who Was John Locke?

John Locke was a 17th-century British philosopher who contributed to modern political discourse and the foundations of empiricism. He would influence George Berkley and David Hume and a modification of social contract theory that would lay the foundation of the ideas of liberal democracy and classical republicanism.

Locke would be an enormously influential figure in the formation of the early government of the United States and the drafting of that country's constitution. His political theory would also influence the ideas of Jean-Jacques Rousseau, Immanuel Kant, John Rawls, and Robert Nozick.

Many consider Locke's views similar to modern libertarian thoughts, though, like most political philosophers, it is difficult to pigeonhole him into a single ideology.

Locke’s Empiricism

Locke is considered the first of the three great British Empiricists. He objected strongly to the claims made by René Descartes that there are a priori principles from which knowledge can be derived. Locke insisted instead that human beings are born as blank slates or as a “tabula rasa,” as later philosophers would refer to it.

Locke denied that there was an essential human nature and claimed that everything a human being is comes from the senses. He distinguished between simple ideas, like color sensations, tastes, sounds, and shapes (these are similar to what David Hume would call impressions), and complex ideas such as cause and effect, identity, mathematics, and any abstract concept.

Though his writing served as the foundation of the Empiricist school of thought, it is now considered far too simplistic. While his writing received critiques from rationalists, it is often thought that the most devastating critiques came from empiricists themselves.

For instance, Locke objected to the idea that Descartes put forth that a triangle is an a priori concept. He said instead that the idea of a triangle was merely a reflection on the physical form of a triangle. George Berkley pointed out that for this to be true, you would have to simultaneously imagine a triangle that is equilateral, isosceles, and scalene.

While Locke heavily influenced David Hume, he took his ideas to their utmost logical extreme. Hume rejected the idea of there being no human nature; however, his moral theory was based on the concept that human intuitions form the basis of morality. This is a refutation of Locke’s basic claims that the human mind is a blank slate.

Locke’s Political Philosophy

Locke based the foundation of his political theory on the idea of inalienable rights. Locke said that these rights came from God as the creator of human beings. Human beings were the property of God, and Locke claimed that denying the rights of human beings that God had given them was an affront to God.

In this way, Locke had established “negative rights” for all human beings. Humans had the inalienable rights of life, liberty, property, and the pursuit of their own goals. This is in contrast to “positive rights” such as the right to equality, health care, or a living wage that have been claimed as rights by political philosophers since Locke.

Locke adopted the idea of social contract theory to form the basis of what he considered a legitimate government. The most famous previous version of social contract theory was that of Thomas Hobbes, who used the theory to form the basis of a monarchy.

Locke found this form of government to be in contradiction to his ideas of inalienable rights, and while he agreed with the idea that governments were formed by the agreement of society, he disagreed with the idea that they were looking for security as the primary goal of society. Locke instead based his primary value of government on the idea of liberty, and he claimed that the only legitimate form of government was one that operated on the explicit consent of the governed.

This is where Locke’s philosophy becomes a bit complex. His ideal government was that of a Democratic Republic where policy was dictated by the will of the majority, but individual rights were to be respected. Contemporary governments have accomplished this through a series of checks and balances.

Locke believed that the rights that I have described above had come from God, but at the same time, he also believed that Democracy could result in some of the property of the citizens being redistributed. His justification for this was that once a government was formed, it had to function as a ruling body, and functioning as a single body majority rules was the most fair way to implement any policy.

However, because each individual in the body politic would know that while sometimes they would be on the winning side of the majority, other times they may not, and this awareness would somewhat curb the urge to wield tyranny against their fellow citizens. In this way, what Locke was saying was that while the majority could become an oppressive force, the individual’s fear of that force justified the upholding of certain rights among the citizens. The majority would respect the rights of others on the basis of wanting their own rights to be respected on similar issues, and Locke felt that “the golden rule” would ultimately dictate action.

This proved wrong in the short term, but governments that have formed on these principles have been essentially progressive, and the rights of individuals have increased over time as Democratic Republics have developed. Still, both the ideas of individual liberty and democratic principles are often at odds with each other, and the question of positive rights instead of Locke’s strictly negative rights still remains. Future social contract theorists Jean-Jacques Rousseau and John Rawls would both expand on this concept.

@me: "Who would Locke, Hobbes, Hume, and Kant side with in the debate between John Rawls and Robert Nozick?

Nozik doesn’t fully develop the notion of self-possession. He borrows it from an earlier philosopher John Locke. Locke accounted for the rise of private property from the state of nature by a chain of reasoning very similar to the one that Nozik and the Libertarians use. Locke said, “ Private property arises because when we mix our labor with things, unowned things, we come to acquire a property right in those things. The reason? The reason is that we own our own labor. And the reason for that is that we are the proprietors, the owners of our own person. So to examine the moral force of the Libertarian claim that we own ourselves, we need to turn to John Locke and examine his account of private property and self ownership.

Great article Robephiles! So much of this has disappeared from modern education. Pity.

Greed! I can't even imagine how to philosophically justify corporate rights. We have had it hard enough with human beings.

Lee Raynor from Citra Florida on July 05, 2011:

Very timely Hub

It's amazing to me that after 235 years, we are still debating the same issues of individual rights VS collective rights.

Now SCOTUS has decided that corporations have the rights as individuals. Where does this philosophy come from?

I thought it was a good thing to post on the 4th of July.

I really like hubs on philosophy and John Locke's writings are certainly important today with our political parties arguing about the constitution.
