Knowledge - Conditions of Knowledge

The first philosopher to define knowledge was Plato, who stated that for us to say that we know something:

1. It must be true.
2. We must actually believe it.
3. There must be sufficient evidence for it (it must be justified).

Using the following table, think of things that fit these criteria in different ways (true but not justified belief, untrue but justified, etc.). I have given you one example to start you off.

Statement	True?	Justified?	Believed?	Explanation
I see a red car	Yes	Yes	Yes	This would be true if I saw the car in normal conditions and was consciously aware of the fact (i.e. I believed it).
There is life on a planet in the Sirius star system	yes	no	yes	A person may believe thsi and it may one day prove to be true. However, if their justification is just a hunch or intuition, they cannot be said to know it.
Jim is on the phone	no	yes	yes	Someone may answer the phone and think that they hear someone's voice (Jim) when in fact it is someone else (say, Fred). In this case they have justification, they believe it - but it is untrue, a mistake.
The moon is made of cheese	no	no	yes	I may believe this as a child, or on an insane whim, but it is not true or justified - therefore not knowledge.
UFOs exist	yes	yes	no	I may see a UFO or flying saucer and therefore it may be true and have justification. However, if I choose to doubt my experience, I cannot know it (I do not believe it). The same would apply if I had forgotten or repressed such an experience (knowledge has to be conscious).
God exists	yes	no	no	This may be true, but if there is no justification and I do not consciously hold to this view, I do not know it.
There is a blue chiar in the next room	no	yes	no	There may be justification of this - someone might tell me. However, if I don't hear them, I cannot be said to belief it. Also, if the statement further turns out to be false, the statement is neither true nor believed (though possibly justified).
The Sun is made of magarine	no	no	no	Something which is not true, has no justification and is not consciously held by anyone cannot be called knowledge.
