Enthymeme. The hidden logic that we use every day.

When we talk about rhetoric or logic, we often imagine philosophers of Ancient Greece, deeply pondering the world, or lawyers building arguments in court. However, the truth is that the foundations of these disciplines are used in our everyday lives, and one of the most common forms is the enthymeme.

If you have ever drawn a conclusion without detailing all the premises, then you have most likely used an enthymeme. Essentially, an enthymeme is a shortened syllogism, meaning a logical structure in which one of the premises is omitted because it is obvious to the listener or interlocutor.

To delve deeper into the concept of enthymeme, let's first clarify what a syllogism is. A syllogism is a classical form of logic that was detailed by Aristotle. It consists of three parts:

A syllogism works by combining general and specific facts that lead to an obvious conclusion. It is a powerful tool in logic and rhetoric that helps to argue any claims based on clear and structured logic.

An enthymeme, unlike a complete syllogism, omits one of the premises. This can be either a major or a minor premise – it all depends on what information is considered common knowledge or easily inferred from the speaker's words. For example:

"Socrates is mortal because he is a human."

Here we have omitted the major premise "All humans are mortal," as it is obvious to the audience. This is why enthymemes are so effective: they allow for concise speech while maintaining a logic that the listener or reader can easily reconstruct in their mind.

Enthymemes are not limited to scientific or academic texts. On the contrary, we use them everywhere: in daily conversations, advertising, politics, and even on social media. They allow us to save time by providing conclusions that do not require a full explanation of all the details. Here are a few examples of enthymemes in modern life:

Advertising slogans almost always use enthymemes to influence the buyer. For example:

"This toothpaste is recommended by dentists."

The slogan implies that if dentists recommend it, then it is better or more beneficial than other toothpastes. The omitted part: "Dentists know about teeth and oral health, so their recommendation is authoritative."

In political debates, enthymemes are used to create persuasive arguments without unnecessary details. Here is an example:

"We need to lower taxes to stimulate the economy."

This argument implies that lowering taxes automatically leads to economic growth. The omitted premise is that the economy improves through increased consumption or investment when people have more money left after paying taxes.

Even in ordinary communication, we use enthymemes. Imagine a situation:

"He will be late; he is always late."

Here, the omitted premise is that past behavior is a reliable indicator of future behavior. We do not explain this, but we imply that since the person is consistently late, it can be expected to happen again.

Enthymemes allow us to communicate effectively and condense information, but they can also be used for manipulation. Since one of the premises is hidden, the listener or reader may not be aware of the entire logic of the conclusion. This can lead to decisions being made based on incomplete or misleading information.

For example, in political speeches, enthymemes are often used to simplify complex economic or social issues. People may subconsciously agree with arguments that lack sufficient foundation because the omitted parts seem obvious or logical at first glance.

In advertising, enthymemes can deliberately omit important details about a product to create a positive impression without providing the full picture. The slogan "Buy this phone because it is the best" does not explain by what criteria it is the best and why other options are worse.

In modern culture, the enthymeme has become an almost indispensable part of our communication. It saves time by allowing us to quickly build arguments and draw conclusions. However, it is important to remember that the power of the enthymeme depends on the trust between the speaker and the listener. If the listener believes they know the omitted part of the argument, it can create a sense of logical completeness, even if the argument has significant weaknesses.

The simplicity of the enthymeme sometimes borders on trickery, especially when used for manipulation. But it is also a tool for more effective communication, especially in situations of time scarcity or when there is no need to delve into details. Also read interesting posts on topics:
