Definition

What is it?

An enthymeme is a type of argument where one part of the argument is left unsaid because it's assumed the audience already knows or agrees with it. It's like a logical puzzle with a missing piece that everyone already understands.

Simple Example

Quick Example

Imagine your friend says, 'It's raining, so I'll take my umbrella.' The unsaid part is: 'When it rains, one needs an umbrella.' Everyone knows this, so your friend doesn't need to say it.

Worked Example

Step-by-Step

Let's look at an enthymeme: 'He's a great cricketer, so he'll score a century today.'
---Step 1: Identify the stated premise. The stated premise is: 'He's a great cricketer.'
---Step 2: Identify the stated conclusion. The stated conclusion is: 'He'll score a century today.'
---Step 3: Think about what logical connection is missing between the premise and the conclusion. What idea links 'great cricketer' to 'scoring a century'?
---Step 4: The missing, unstated premise is: 'Great cricketers often score centuries.'
---Step 5: Combine all parts to form the full argument: 'He's a great cricketer (premise), and great cricketers often score centuries (unstated premise), therefore he'll score a century today (conclusion).'
---Answer: The enthymeme relies on the unstated premise that great cricketers score centuries.

Why It Matters

Understanding enthymemes helps you see how people persuade others, even when they don't say everything directly. This skill is crucial for future journalists, lawyers, and politicians who need to build strong, convincing arguments or understand hidden messages in speeches and news.

Common Mistakes

MISTAKE: Thinking an enthymeme is just an incomplete sentence. | CORRECTION: An enthymeme is an incomplete *argument* where a logical step is missing but understood, not just any sentence that's cut short.

MISTAKE: Believing the missing part of an enthymeme is always a secret or trick. | CORRECTION: The missing part is usually a common truth or belief that the speaker assumes everyone shares, making the argument more efficient.

MISTAKE: Confusing an enthymeme with a fallacy (a flawed argument). | CORRECTION: An enthymeme is a *structure* of argument with an unstated premise; it can be logically sound or unsound, but it's not a fallacy itself.

Practice Questions

QUESTION: What is the unstated premise in: 'My phone battery is low, so I need to charge it.' | ANSWER: Unstated premise: 'When a phone battery is low, it needs to be charged.'

QUESTION: Identify the enthymeme in this statement: 'The new express train started, so my daily commute will be faster.' What is the hidden assumption? | ANSWER: The enthymeme is the whole statement. The hidden assumption/unstated premise is: 'Express trains make commutes faster.'

QUESTION: A politician says, 'We must ban plastic bags because they harm the environment.' Explain the enthymeme by stating its explicit and implicit parts. | ANSWER: Explicit premise: 'Plastic bags harm the environment.' | Explicit conclusion: 'We must ban plastic bags.' | Implicit (unstated) premise: 'Things that harm the environment should be banned.'

Real World Connection

In the Real World

You see enthymemes often in advertisements! When a mobile network ad says, 'Get our new plan, and enjoy seamless streaming!' The unstated idea is: 'Seamless streaming is desirable, and our plan provides it.' Political speeches also use them to connect with voters by appealing to shared values without explicitly stating them.
