## What makes a strong and valid argument?

Definition: A **strong argument** is a non-deductive **argument** that succeeds in providing probable, but not conclusive, logical support for its conclusion. A **weak argument** is a non-deductive **argument** that fails to provide probable support for its conclusion.

## Is it possible to prove that an argument is valid?

A **sound argument** must have a **true** conclusion. **TRUE**: If an **argument is sound**, then it is **valid** and has all **true** premises. Since it is **valid**, the **argument** is such that if all the premises are **true**, then the conclusion must be **true**. If a **valid argument** has a false conclusion, then at least one premise must be false.

## What does it mean for an argument to be formally valid?

An **argument** is termed **formally valid** if it has structural self-consistency, i.e. if when the operands between premises are all true, the derived conclusion is always also true. In the third example, the initial premises cannot logically result in the conclusion and is therefore categorized as an invalid **argument**.

## Are all arguments valid?

**All valid arguments have all true** premises and **true** conclusions. **All** sound **arguments** are **valid arguments**. If an **argument** is **valid**, then it must have at least one **true** premise. Every **valid argument** is a sound **argument**.

## What are the 5 keys to winning an argument?

## What is required to prove an argument?

An **argument**, more fully a premise–conclusion **argument**, is a two-part system composed of premises and conclusion. An **argument** is valid if and only if its conclusion is a consequence of its premises. To determine validity in non-obvious cases deductive reasoning is **required**.

## Can a valid argument have all false premises but a true conclusion?

No, a **valid argument** cannot **have all false premises** and derive from them a **true conclusion**.

## Is logic always right?

**Logic** is a very effective tool for persuading an audience about the accuracy of an argument. However, people are not **always** persuaded by **logic**. Sometimes audiences are not persuaded because they have used values or emotions instead of **logic** to reach conclusions.

## What is validity and soundness of an argument?

A deductive **argument** is said to be **valid** if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. A deductive **argument** is **sound** if and only if it is both **valid**, and all of its premises are actually true.

## What is a valid argument in critical thinking?

**Validity** is a most important concept in **critical thinking**. A **valid argument** is one where the conclusion follows logically from the premises. An **argument** is **valid** if and only if there is no logically possible situation in which the premises are true and the conclusion is false.

## Can something be logical but not true?

In **logic**, an argument **can** be invalid even if its conclusion is **true**, and an argument **can** be **valid** even if its conclusion is **false**. All of the premises are **true**, and so is the conclusion, **but** it’s **not** a **valid** argument.

## Can valid arguments have false premises?

A **valid argument can have false premises**; and it **can have** a **false** conclusion. But if a **valid argument has** all **true premises**, then it must **have** a **true** conclusion. Since a **sound argument** is **valid**, it is such that if all the **premises** are **true** then the conclusion must be **true**.

## Can a valid argument be unsound?

**Arguments can** be **valid** but still have one or more false premises. If an **argument** is both **valid** and has all true premises, we will say that the **argument** is sound. An **argument** is **unsound** if it either has a false premise, or is invalid.

## Can a cogent argument have a false conclusion?

A **cogent** inductive **argument** doesn’t rule out even this combination—that is, it’s possible but unlikely that a **cogent** inductive **argument has** true premises and a **false conclusion**. For instance, if it turns out that Tweety is an ostrich, then the premises are true but the **conclusion** is **false**.
