When dissecting arguments, please try to examine its two parts: premises and conclusion. Both are made of true or false statements. The premises are designed to be support statements, leading to a conclusion. However, if an argument has a false conclusion, it is unsound. Although please remember that it can still be valid. "If an argument has at least one false premise, it is unsound. If the premises don't imply the conclusion, then the argument is invalid"
Here is an example of an unsound argument:
1. All heavenly bodies are comprised of blue cheese.
2. The moon is a heavenly body.
3. Thus, the moon is made of blue cheese.
Since statement 1 is false, it deems the argument as unsound.
Another idea includes:
1. All heavenly bodies rotate around the earth.
2. The sun is a celestial body.
3. Therefore, the sun rotates around the earth.
This argument is unsound because premise (1) is false. Even if an argument is valid and has a true conclusion, it can still be unsound if its premise is false.
