A review of “David Hume” (audiobook)

“It is evident, that all the sciences have a relation, greater or less, to human nature: and that however wide any of them may seem to run from it, they still return back by one passage or another. Even Mathematics, Natural Philosophy, and Natural Religion, are in some measure dependent on the science of MAN; since the lie under the cognizance of men, and are judged of by their powers and faculties … consequently we ourselves are not only the beings, that reason, but also one of the objects, concerning which we reason.”

– Introduction to David Hume’s “A Treatise of Human Nature” (1739-1740), as written by the author himself

I had heard very little about David Hume, before listening to this audiobook. But after listening to this presentation, I was (and still am) convinced that he is one of the greatest philosophers of all time. His influence was massive, and he wrote on many topics – something that was more common then. For example, he wrote on history, politics, and economics as well as philosophy. But he is most famous for his original contributions to the philosophy of science, and the debate over what is the most reliable foundation of human knowledge. It was in this regard that Immanuel Kant once paid him a heartfelt compliment. Kant said that “the suggestion of David Hume was the very thing, which many years ago first awakened me from my dogmatic slumber.” (See the full quote and its citation here.)

A review of “The Classical Economists” (audiobook)

“The statesman, who should attempt to direct private people in what manner they ought to employ their capitals, would not only load himself with a most unnecessary attention, but assume an authority which could safely be trusted, not only to no single person, but to no council or senate whatever, and which would nowhere be so dangerous as in the hands of a man who had folly and presumption enough to fancy himself fit to exercise it.”

– Adam Smith’s “The Wealth of Nations” (1776), Book IV, Chapter II

David Hume criticized social contract theory severely …

“My intention here is not to exclude the consent of the people from being one just foundation of government where it has place. It is surely the best and most sacred of any. I only pretend, that it has very seldom had place in any degree, and never almost in its full extent. And that therefore some other foundation of government must also be admitted.”

– David Hume's “Essays, Moral, Political, and Literary” (1752), Part II, Essay XII (entitled “Of the Original Contract”)

Do governments require the “consent of the people”? If you think they do, you might be a believer in social contract theory, even if you don’t realize it yet. The idea that governments have actual duties to their people, and not just people having one-way duties to their governments, is at the foundation of every democracy; and is at the heart of social contract theory in every way.

What is social contract theory, and why is it important?

In a nutshell, this social contract theory is basically the idea that there is an agreement between government and the people, which believers in this theory may or may not believe to have been written down on paper. In this agreement, it is held that governments agree to do certain things for their people, and that the people agree to do certain things for their society. These would include obeying the laws that their governments are actually authorized to make under this agreement – although not all laws would be authorized by these agreements, since some of these laws might be considered “unconstitutional” under its terms. (More on that later in this post – for now, I will just explain what social contract theory is at its most basic level.) What exactly the duties of each party might be is a matter of some controversy, I should acknowledge here, even among social contract theorists. Thus, I will not attempt here to specify numerous details of the duties owed by either side in this agreement. This would be too long a task for a single blog post, in fact, and would be beyond the scope of a blog like mine. Rather, I will attempt to show how social contract theory influenced the United States Constitution (since I am an American), and show how our own Constitution owes much to the English philosopher John Locke in this regard, since he was a great social contract theorist in a previous century. (For more on the basics of this theory, I will refer interested readers to another of my blog posts, which I link to here. This post will focus more on how this theory has been applied in actual practice, at least in my own country.)

Thomas Hobbes

What's the difference between a “democracy” and a “republic”?

"The United States shall guarantee to every state in this union, a republican form of government ... "

- Article 4, Section 4 of the United States Constitution

Is there a difference between a "democracy" and a "republic"?

The meaning of words tends to change over time, and the words "democracy" and "republic" are no different in this respect. For example, if you were to ask Americans on the streets today whether there's a difference between the two words, many would reply that they are the same (or, at least, close to the same), and some dictionaries even define them as synonymous today. Among them is the website of Princeton University, which offers multiple definitions for each word. One of these definitions is even the same for both words, and their website lists the two words as accepted synonyms for each other in this context. Their shared definition, in case you're wondering, is that they are "a political system in which the supreme power lies in a body of citizens who can elect people to represent them" (Source: entry on "democracy" and entry on "republic") The contemporary use of these words is thus somewhat interchangeable, and the common meaning of these words would admit few (if any) distinctions between them.

James Madison

The Founding Fathers thought there actually was ...

Yet there is a historical distinction between the two that our Founding Fathers recognized. One of them even offered these definitions explicitly in the Federalist Papers. These definitions show a distinction between the two in the mind of this particular Founding Father. This distinction existed in his mind long before the Constitutional Convention, even if he had not yet included it in the Federalist Papers. The Founding Father was James Madison, and he essentially said that a democracy was a direct democracy - or in other words, where people vote on everything directly in person. His phrase for a direct democracy was a "pure democracy," and he defined it as "a society consisting of a small number of citizens, who assemble and administer the government in person" (Source: Federalist No. 10). A good example of this system might be Ancient Athens, the most successful city-state within the lost world of Ancient Greece. Madison's definition of a republic, by contrast, was that it was "a government in which the scheme of representation takes place" (Source: Federalist No. 10). In other words, he said, the definition of a republic is where the people elect others to make those decisions for them. Which is better, you might ask? Are there greater dangers in delegating these powers to our elected representatives, or do the greatest dangers come from other sources, like the "tyranny of the majority"?

David Hume and “The Wealth of Nations”

"Commerce and manufactures gradually introduced order and good government, and with them the liberty and security of individuals, among the inhabitants of the country, who had before lived almost in a continual state of war with their neighbors, and of servile dependency upon their superiors. This, though it has been the least observed, is by far the most important of all their effects. Mr. Hume is the only writer who, so far as I know, has hitherto taken notice of it."

- Adam Smith's "The Wealth of Nations," Book III, Chapter IV

Most people today have never heard of the Scottish philosopher David Hume, a great figure of the Scottish Enlightenment. But many people today have heard of the man who was probably his best friend - a man who was greatly influenced by his philosophy (political, economic, and otherwise), and influenced him in his turn. That man was his fellow Scotsman Adam Smith.

Statues of David Hume and Adam Smith

This is not to say that Mr. Hume's accomplishments were just in economics, or that Adam Smith was the only person that he influenced - he influenced many people, in the natural sciences and elsewhere. However, I shall focus this post on economics, and his influence on Adam Smith; and leave the coverage of his empiricism - and his other contributions to the philosophy of science - to others.
