Study Notes

Understanding Arguments

  • An argument involves a set of statements (premises) offering support for another statement (the conclusion)
  • The purpose of an argument is to persuade or justify a claim

Argument Characteristics

  • Minimum requirement of one premise and one conclusion
  • Premises should be statements that provide evidence or reasons
  • The conclusion represents the argument's central point
  • Arguments can be categorized as valid/invalid, sound/unsound

Recognizing Arguments

  • Differentiate arguments from explanations, descriptions, and personal opinions
  • Premise indicators include: because, since, given that
  • Conclusion indicators include: therefore, thus, hence, so, consequently

Argument Example

  • Premise 1: All humans need oxygen to survive
  • Premise 2: John is a human
  • Conclusion: Therefore, John needs oxygen to survive

Non-Argument Example

  • Statement: John needs oxygen because all humans do
  • Note: This is an explanation instead of an argument

Premises Defined

  • A premise offers evidence or support for a conclusion

Conclusions Defined

  • A conclusion is what the premises aim to prove as true

Premises and Conclusions Example

  • Premise 1: If it rains, the ground will be wet
  • Premise 2: It is raining
  • Conclusion: Therefore, the ground is wet

Argument Aspects

  • Truth Content: Verification of premises in reality
  • Logical Content: Premises' logical connection to the conclusion

Argument Types Based on Logic/Truth

  • Valid: Conclusion logically follows the premises
  • Invalid: Premises fail to provide logical support
  • Sound: Valid argument with true premises
  • Unsound: Argument is invalid or has false premises

Sound Argument Example

  • Premise 1: All mammals have lungs
  • Premise 2: A dog is a mammal
  • Conclusion: Therefore, a dog has lungs

Valid but Unsound Argument Example

  • Premise 1: All birds can talk (False)
  • Premise 2: A parrot is a bird (True)
  • Conclusion: Therefore, a parrot can talk

Invalid Argument Example

  • Premise 1: Some cats are black
  • Premise 2: Some dogs are black
  • Conclusion: Therefore, some dogs are cats

Argument Evaluation

  • Verify truthfulness of the premises
  • Confirm logical flow from premises to conclusion
  • Identify logical fallacies

Common Logical Fallacies

  • Strawman: Distorting an argument to make it easier to challenge
  • Ad Hominem: Attacking the person presenting the argument
  • False Dilemma: Limiting options to only two when more exist
  • Circular Reasoning: Using the conclusion as a supporting premise
