NVC Non-Violent Communication, how to identify needs in self and others and how to speak without shaming, blaming and criticising is one of the four or five disciplines that I’d like everyone in the world to know how to do.
Language is important, but as Moreno said:
The analysis of language, useful as it is in itself. does not lead to any change in behavior. It has to be followed up by methods of action learning which train the pupil to think and act below and beyond the boundaries of language.
That’s why I think there are four or five disciplines, but none of them sufficient alone.
