What is the relativism objection ?
Claims that there is no objective truth and that what we know is relative to society
What is an example of JTB from false premises? (Gettier Case)
- Smith & Jones
Both apply for the same job. Smith is told that Jones will get the job. Jones has counted 10 coins in his pocket. So, Smith deduces that the man who will get the job has 10 coins in his pocket. However, Smith gets the job and - unknown to him- has 10 coins in his pocket. - Jones & Brown
Smith knows that Jones owns a Ford. Smith guesses that Brown is in Barcelona. Smith creates the disjunction;
•Jones owns a Ford, or
•Brown is in Barcelona, or
•Both are true
However, Jones has sold his Ford. But, Brown happens to be in Barcelona.
