The didactic environment of a discussion club. There are three stages for any discussion:

• Agreement on basic principles.
• Agreement about details. What to do and how to do it.
• Agreement in way of application. How to apply in to different conditions.

The first level of agreement is easy to achieve. The real battle starts at the second stage when the discussion goes into the offensive if there are two sides. Arguments and counterarguments arise, analogies are thrown left and right.

It takes a long and effortful way, and only really strong participants can walk this slippery slope of opposing opinions.

The last stage is where the stress test comes into play, we have to test what we have agreed on in new conditions. Start with ideal and gradually move to anything but ideal.
