Is there still a possibility of public truth?
The prime condition for that would be that you pose your own questions, not just answer them. The questions of others have a distorting influence, one adapts to them, accepts words and concepts that should be avoided at all costs.
Ideally, you should use only words which you have filled with new meaning.
