Study Notes
Radical Skepticism
- Radical skepticism questions if knowledge is attainable.
- It differs from everyday skepticism, which questions specifics.
- It challenges the very possibility of knowledge.
Arguments in Philosophy
- A philosophical argument isn't a quarrel; it's a logical process.
- A conclusion is presented as following from premises (supporting claims).
- Premises are statements that support the conclusion.
Types of Arguments
- Deductive Arguments:
- If premises are true, the conclusion must be true.
- A certain relationship exists between premises and conclusion.
- Example: All humans are mortal, Socrates is human, therefore Socrates is mortal.
- Inductive Arguments:
- Conclusion is likely or probable based on premises.
- Premises give evidence, but don't guarantee the conclusion.
- Example: Most birds fly, a penguin is a bird, so a penguin likely flies.
Validity and Soundness
- Validity: The structure of an argument; if premises are true, the conclusion must be true.
- Soundness: Validity + true premises.
- Example: All cats have tails, Felix is a cat, so Felix has a tail. This argument is valid and sound if both premises are true.
Inductive Arguments (Strength and Probability)
- Strength: In inductive arguments, if premises make the conclusion likely, it's considered strong.
- Statistical Reasoning: Arguments using statistics show the probability of a conclusion.
- Example: 35/103 students walk to school, so about a third of students at the school likely walk.
Inference to the Best Explanation
- The conclusion is the best explanation for the premises.
- Example: Car engine sputtered and stopped, gas gauge reads empty. The car is out of gas (best explanation).
Certainty, Probability, and Chance
- Certainty and probability are ambiguous; they're used in many ways.
- In mathematics, probability is a function between 0 and 1, and displays how likely something is.
- Everyday use of probability can differ from the mathematical definition.
Evaluating Arguments
- Philosophers evaluate arguments for validity and soundness in deductive reasoning.
- In inductive reasoning, philosophers asses strength.
- A good argument's conclusion logically follows from true premises.
Skeptical Argument Example (Descartes)
- Descartes argued that senses can deceive, so we shouldn't blindly trust them.
- This is a radical skeptical argument questioning the reliability of knowledge.
