Knowledge is perception |
-if knowledge is perception, and any creature is capable of perceiving/knowing, then knowledge is not a human characteristic -if knowledge is perception, then whatever I perceive is true. if each individual perceives things differently then the world cannot be one thing. -Perception comes in degrees, knowledge does not. you either know something or you don't. |

Man is the measure of all things |
If man is the measure of all things, then it is impossible for someone to be mistaken, since how it is to that person is how it "is". Nobody can be wiser than anyone else, because we are all right. -this leaves no room for specialization or predicting the future (doctors) |

Heraclitean View: there are no fixed things, there is only motion. constant change |
-things constantly changing depending on your viewpoint. what appeared to you to be a certain way minutes ago is totally different now. -when you are no longer perceiving something you no longer know it, memory does not amount to knowledge -after the perception is over, the perceiver is no longer the same person. -knowledge must be of "what is" if everything is constantly changing and in motion, then nothing ever "is" |

Knowledge is true judgment -how is false judgment possible? |
-false judgment is not possible because we either know something or we don't. a man who is judging something which is not, is judging nothing. a man who is judging nothing, is not judging at all. judging which is not = no judgment at all. a man who has two things before his mind when he judges cannot possibly judge one thing to be the other. we must know the things of which we are judging in order to judge them, therefore we cannot possibly mistake one thing for another if we know what each of those things is. if a man has only one thing before his mind in judging, and the other is not present to him at all, he will never judge one to be the other. |

Knowledge is true judgment with an account Dream Theory |
The dream theory suggests that there are primary elements of which everything is composed that have no account, each can only be named
Elements: are unaccountable, and unknowable, but perceivable. Complexes: are knowable and perceivable, objects of true judgment but you must know the elements in order to know the complexes. you learn by acquiring the building blocks first |

knowledge is true judgment with an account what does it mean to give an account |
going through something element by element is giving an account. NO we can do this and still not have knowledge to give an account is being able to verbally state what you are talking about. NO. knowledge cannot be so only once spoken, if not in your thoughts to give an account is to be able to differentiate that thing from something else. NO. the definition of knowledge is circular; you need knowledge of everything in order to process knowledge of one thing. you cannot pass judgment without first having knowledge of something. |
