Plato

So I was just rereading my philosophy notes from this semester and there is something that has been bothering me and it lies in one of Plato’s theories.

No one wishes to harm themselves
and evil is what is ultimately harmful,
therefore no one does evil intentionally.

Aristotle tried to disprove this by saying there was more then one kind of knowledge. I don’t agree with this either I think Plato was right one he said there was only one type. After much thought I finally think I came up with a solution to why this is wrong. I believe issue is found in the premise, “evil is what is ultimately harmful,” and more specifically the word “ultimately.” I believe if you take this word out and make it: evil is what is harmful then it will fit. Because “what is harmful” encompasses all people and all harm. So acts that only cause some harm but aren’t ultimately harmful will be considered evil.
