I'm on a course at college and I'm a little stuck?

Question

Whats the diffence between radical and rational theories and which theorist supports which thoughts, if you know of any that might help i'd be gratefull if you can help me understand it all a little more.

Answer 1

In our Darwinian world, a rational theory is one where the
majority chooses it so; well,thats what we are taught but i
admit doesnt always happen(a class may choose the less
rational one,but the presiding authority-may be one teacher
or not- acts against).
A radical theory,say.communism,looks
and sounds rational until it is subject not only to real life but
also to darwinian criticism. Criticism such as- what about the
free-market and its unhinderance? (.Cuba and vietnam are
real life examples)
Another radical theory is the theory of mass representation in politics; And it IS radical, and has not been
subject to enough (darwinian) criticism; this can be seen if
we said that random selection would be just as democratic-
for all democracy means is service-to-the-people by the
people(and random selection meets that as does mass
representation!).
So you should be able to see that "radical"
theories are held or are embedded in the very fabric of our
world.And beware those who say otherwise(!)

Answer 2

I'm guessing, to be honest, that a radical theory is a new insight that is totally flying in the face of previous theories, something unsuspected and out of the blue. A rational theory is more 'commonsense' in approach, based on (scientific style) research.
