1."There is only one good, knowledge, and one evil, ignorance." How is this so? If that is then the case, then why do we see in color, yet not in black and white? It is impossible for there to be only god and only evil, all humans are both good and evil. With some, the balance between the two may be more good than evil, and more evil than good. Nevertheless one can not be simply good nor simply evil. Example, an elderly woman while walking home gets mugged and knocked over by a man. YOU might say that this was an act of pure evil and thus the man WAS pure evil; but i say something different. Do the intentions of a man not count for anything? Say the robber needed money because his son was in terrible condition and his family needed the money for medical purposes... Yes what he did was most certainly wrong, but his motivation was to help someone in need, a loved one; or vice versa. If you do the wrong thong for the right reason are you evil? What about if you do the right thing for the wrong reason, does that make that person any better?
2. Plato believes that justice is determined by the four greta virtues; courage, wisdom, temperance and justice. He uses these characteristics to identify what justice in a state is. He gives examples how certain professions attract certain types of people. One example would be that brave, strong and courageous people are fit for defensive and political professions.
3. Plato believed that the perfect government would be run by the best, acsentially an aristocracy; "run by the best". I would agree to the aspect of being run by the best, but i would ask him, does higher rankings and more money mean you are the more superior in the race? Does Plato believe in self made man? I feel that government simply controlled by aristocrats, the most educated (we must keep in mind the types of intelligence, innate wisdom vs. educated stupidity) and richest would eventually become a monarchy. This is because eventually the richest family(ies) would be able to afford the best education and it would then be quite possible that they could then declare themselves the best of the race and (according to Plato's ideal) they then would have the right to rule the utopia.
4. My ideal republic/ lifestyle would be a democracy where the people were overseen by an elected few, and that there was no paper money, but instead each person with a trade would help each other. I believe this is a simpler approach. THis is how it would work, some people would be lawyers, others shoe makers, clothing sellers, farmers, ranchers, in short, each person would have something to bring to the the table and something to take back with them. "A pair of shoes for a week's meal" things like that. Without the complication of money. THis system (as long as people aren't corrupted with their own greed) would last for a long time, you take what you need and give what you don't. This would not only encourage the population to interact and get to know each other, but also encourage and stress the importance of education, discovering yourself, and being able to share your love of... (profession) with everyone else.
5. "The only thing standing in the way of knowledge is our insistence that the visual universe is reality." This follows up on the line that everything is not as it seems. If one only believed in things they could see then there would be no such thing as love, physics, imagination, history and more. To only believe in what you see means that first of all, your knowledge is very very limited and second, that you have no trust. To have faith and believe you'd nee physical evidence and some things just existence that can't be seen. Feelings can't be seen (though emotions can)but you can feel them and they are most certainly in existence. Important things like that would then not exist to that person.
