Theory about Debating (TaD)

My resources for this theory are:
The text of Jo Reichertz "Qualitativ Sozial Research" in German " Qualitative Sozialforschung",
point 2:
http://www.qualitative-research.net/fqs-texte/2-00/2-00reichertz-d.htm
and the things I have heard from J.Hopfner this morning in the lecture of general pedagogics. (Allgemeine Pädagogik)

So thats my theory:
I) 4 ideal types of argueing

Wenn I do a declaration about reality, I have to watch out which arguments I use for it.
Jo Reichertz differentiates 4 ideal types of used arguments in siences.
1) The empiric type
-> The sentence:" All swans are white" is guilty because I have seen just white swans at the lake.
2) The rational type
-> This Argument uses logic and rationality to convine the others of the own reality. For example: 1 + 1 = 2 because we humans have decided that 1 + 1 = 2 is true.
3) The authority type
-> Something I say is guilty, because a very important person said it too.
For example: God exists, because it stands in the bible. Or the theory of relativity is true because Einstein said it, and he was a genious.
4) The own ability to convince others type
-> This way of argueing is the easiest way. Something is true, because I say it, (+in a way that convinces you.)

II) The difference between written and spoken words.

J.Hopfner, said today in the lecture, that the written word is a stronger argument than the spoken ones. The reason is, that the written word allways can be proved by reading the text the own who arguments has her/his insights (Erkenntnisse) from.
The same happens her. I do a theory which is argueing with something, someone said in a lecture.
It is not sure if
a) I understood J.Hopfner right
b) I got all importent information
c) Im telling you exactly the same as she told me.
At this point of view the written word realy is the stronger argument.

Closuring I could say, that there is a hierachy between this different ideal types of debating.
1) The written word is allway stronger than the spoken word
2) Empiric - Rational - Authority - Ability to convince others, in exactly this order.
I think sience it self is not sure if the empiric type comes before or afterwards the rational one, but I dont want to write about this battle yet.
