What leads to right decisions? This seems to be a subject of debate. In the famous speech of Pericles it was mentioned that  discussion always precedes right action.
That is to say that there is an infinite difference between right action and wrong action. The repercussions go on and on forever. But to be able to perceive the difference before action is taken is very hard. each course of action can be argued for and against. The only way the right choice is made clear is by discussion.

If this was the only thing I had learned from Pericles' speech, that would already be enough. For I have heard of many other approaches the supposedly lead to right action and by experience -my own an others-I have found this idea of Pericles to be the best.

[This idea was also mentioned by Reb Nachman when he says that in the future people will get together and discuss their issues and by means of that, the Truth will be revealed. This is exactly what Pericles said. Discussion always precedes right action.
