In Plato’s Meno, Socrates asks “what if someone is right in his opinion about what the road is, but has not gone there, nor knows the road, would he not also direct them rightly?” (68). Plato sees knowledge as an interlocking of true opinions that are subject to a thorough process to achieve its validity when challenged by doubt. Plato explains that recollection helps one acquire episteme and its most basic aspects of reality. Plato explains that although ortho doxa gives you the same outcome as episteme, it however differs, from episteme since it is not grounded on logos.
Meno, student of Gorgias a sophist, provided a list of different types of virtues, but was unable to articulate a clear generalized definition that encompasses all virtues.
