Yes, which is and has been practiced in AES countries. Just because higher-stage Communism, ie a Stateless, Classless, Moneyless society hasn't been reached globally yet doesn't mean we don't know if it will work or not.

Unless you have investigated a problem, you will be deprived of the right to speak on it. Isn't that too harsh? Not in the least. When you have not probed into a problem, into the present facts and its past history, and know nothing of its essentials, whatever you say about it will undoubtedly be nonsense. Talking nonsense solves no problems, as everyone knows, so why is it unjust to deprive you of the right to speak? Quite a few comrades always keep their eyes shut and talk nonsense, and for a Communist that is disgraceful. How can a Communist keep his eyes shut and talk nonsense?

It won't do!

It won't do!

You must investigate!

You must not talk nonsense!
