Lesson 1.2: Arguments, Premises and Conclusions
Introduction
Welcome, students! 🎉 In this lesson, we will dive into the world of arguments. Our main objective is to understand what an argument is and how it differs from mere assertions, explanations, and disagreements. By the end of this lesson, you will be able to identify the components of an argument, including premises and conclusions, and recognize the key indicators that signal them.
Learning Outcomes
Students should be able to:
- Define the technical meaning of "argument" as a set of premises supporting a conclusion.
- Identify the conclusion (the point being argued for) and the premises (the reasons given).
- Recognize premise and conclusion indicator words like "because", "since", "therefore", "so", and "hence".
- Distinguish between an argument and a non-argument (assertion, report, instruction).
- Differentiate between arguing for a claim and explaining why something is the case.
What is an Argument?
An argument is a structured set of statements where some statements (premises) are put forward as reasons to support another statement (the conclusion). 🤔 It's crucial to understand that not everything you hear or read is an argument!
Example of an Argument
Consider the following:
Premise 1: All humans are mortal.
Premise 2: Socrates is a human.
Conclusion: Therefore, Socrates is mortal.
In this example, the premises provide reason to accept the conclusion. This makes it an argument!
Components of an Argument
Let's break down the components of an argument: premises and conclusions.
Premises
Premises are the statements that provide support for the conclusion. They stand as the foundation of an argument. đź’Ş You can often spot a premise by looking for indicator words such as:
- because
- since
- as shown by
- given that
Conclusion
The conclusion is the main point or claim being made in the argument. It's what the argument seeks to prove. Look for words that signal a conclusion, such as:
- therefore
- so
- hence
- it follows that
Example of Premises and Conclusion
Let’s analyze another argument:
Premise 1: The road is wet.
Premise 2: It is raining.
Conclusion: Therefore, rain causes the road to be wet.
Here, the premises lead us to accept the conclusion that rain creates wet roads, making it an argument!
Differentiating Arguments from Non-Arguments
It's essential to distinguish between what constitutes an argument and what does not. Many times, we encounter assertions, explanations, or instructions that may look like arguments but don’t fit the definition.
Assertions
An assertion is simply a statement that something is true without providing any support or reasons. For example:
Assertion: The sky is blue.
This statement doesn’t provide reasons to support its truth, so it's not an argument.
Explanations
An explanation clarifies why something is the case. For example:
Explanation: The sky appears blue because of the scattering of sunlight by the atmosphere.
While this provides a reason, it's informing rather than arguing for a specific conclusion, thus not qualifying as an argument.
Instructions
Instruction provides direction and typically includes commands. For example:
Instruction: Please close the window.
Here, there is no premise or conclusion involved, just a request.
The Art of Arguing vs. Explaining
Finally, it’s important to understand the difference between arguing for a claim and explaining something. When you argue, you're trying to convince someone of a specific belief or action:
Arguing: You should exercise regularly because it improves your health!
This presents a claim supported by a reason.
In contrast, when you explain, you clarify how something works or why it is:
Explaining: Exercise improves your health because it strengthens the heart and lungs.
Here, there’s no attempt to convince but to inform.
Conclusion
To wrap things up, students, understanding the anatomy of an argument is essential for critical thinking. Recognizing premises, conclusions, and their indicators will enhance your ability to analyze any claim you encounter in everyday life. Arguments play a crucial role in forming opinions, making decisions, and engaging in meaningful discussions. 🗣️
Study Notes
- An argument consists of premises and a conclusion.
- Premises: statements that support the conclusion.
- Conclusion: the main point being argued.
- Indicator words for premises: "because", "since", "as shown by".
- Indicator words for conclusions: "therefore", "so", "hence".
- Differentiate between arguments and non-arguments (assertions, explanations, instructions).
- Know the difference between arguing for a claim and explaining why something is the case.
