# Gettier problem
The Gettier problem challenges the definition of knowledge as "justified true belief." It presents scenarios where one has a belief that is true and justified, but not knowledge due to the reasons for the belief being incorrect.
## Examples of Gettier Problem
1. **Smith and Jones job example**: Smith has strong evidence that Jones will get the job. He also knows that Jones has 10 coins in his pocket. From this, Smith infers that "the man who will get the job has 10 coins in his pocket." However, it turns out that Smith gets the job and also, coincidentally, has 10 coins in his pocket. So, his belief was true and justified, but it wasn't knowledge because the reason for the belief was incorrect.
2. **Sheep in the field example**: A man looks into a field and believes he sees a sheep. His belief is justified because he's looking at a white, fluffy object that looks like a sheep. However, the object is actually a dog that looks like a sheep from a distance. But, unbeknownst to the man, there is a real sheep hiding behind the hill in the field. So, his belief that there is a sheep in the field is true and justified, but it's not knowledge because the reason for the belief was incorrect.
