A commonsense definition of "knowledge" is that it is a belief that is justified and true. Does this make sense? Can you think of things rightly call "knowledge" that are false or unjustified? Question 2: Imagine you see what appears to be a sheep in a field, and claim to know that there is a sheep in the field. Now, it turns out that what you saw was a dog in a sheep outfit, but that there is a sheep in the field; it's on the other side of a hill, where you can't see it. Your belief was justified, and true, but would you call it knowledge?
