that reason, Theaetetus is more concrete than other two earlier views although Socrates is not satisfied at all with Plato’s views in Meno, Republic and Theatetus about the definition of knowledge.After comparing and contrast Plato’s views in Meno, Republic, and Theaetetus, I find that the similarity is the uniqueness of knowledge in Plato’s argument. I also find that the differences are the degree of weaknesses of each of his view. I think Plato presents a strong argument on we define knowledge. In Theaetetus’s case, realistically we can tell that we have some degrees of knowledge by having tests; I think this argument is the best. This definition of knowledge, I think, can apply to our world today. Most importantly, knowledge is involved not only in what we learn, but also in what interpret and process from what we learn in our mind....
