Plato found not only answers but also a method for humans everywhere to work out answers without needing to rely on memorizing the official answers of previous generations and to repeat them over and over again, despite obvious problems with them.

Plato is an author of "dialogues" (The Republic, Laws etc etc.) where the main character is Socrates. Socrates is a philosopher who uses a special kind of dialogue (so-called dialectic dialogue or dialectic method) which leads him to the truth. In other words he follows LOGOS who leads him to uncovering the Truth.

Explanation: Greek word ALETHEIA means "disclosure" and "truth" at the same time. It means that truth is always hidden. Much older Greek philosopher (pre-Socratic) Heraclitus had a dictum: "Truth likes to hide"it seems that Socrates/Plato followed this thesis.
