Part 1: In part 1, Meno and Socrates are talking about what is a virtue. This can be taught? And they used a series of examples.

Is it possible to manage a state well, or a house, or anything at all, if you do not

manage it temperately and justly?

Meno

Surely not.

Socrates

Then whoever manages temperately and justly will manage with temperance and justice?

Meno

That must be.

Socrates

Then both the woman and the man require the same qualities of justice and temperance, if

they are to be good.

Meno

Evidently.

Socrates

And what of a child or an old man? Can they ever hope to be good if they are intemperate

and unjust?

Meno

Surely not.

Socrates

Only if they are temperate and just?

Meno

Yes.

Socrates

So all mankind is good in the same way; for they become good when they acquire the

same qualities.

Meno

So it seems.

Socrates

And I presume, if they had not the same virtue, they would not be good in the same way. 

For me, everyone has the ability to see things in the true light. That’s like a ruler in your life, help you measure your future. And we know what should do, what should not do. virtue may be taught by our parents and our teachers, we may get ideas from our own selves,  or maybe that is the gift from the god. However, there is no single criterion for virtue. We need to use our own knowledge to determine whether is a virtue or not.
