Why only six? Are there ONLY six ideals worthy of consideration? Are the people too stipid to remember more than six?
It's a nice round, small number.
Are there ONLY six ideals worthy of consideration?
There are many more, but then you are just like the other parties. And the more you add, the fewer number of people will agree and join.
Are the people too stipid to remember more than six?
No, the people are not in agreement on more than six. In fact, six may be too many.
