there is a 'controlled folly' type of pride one is allowed.
I do this often, with a special smile on my face - no one ever seems to get what it means. It allows me to experience the benefits of feeling proud to be standing in a group, to experience and enjoy the group's pride, while knowing the whole thing is bollocks.
and there is another word, or another meaning to 'pride'. a sense of having pride in being alive. but that is not group pride.
Gurdjieff had an excellent metaphor or things like group pride or any other identity issue. he described the new system of moving through the universe in a space ship. They realised one day, these inter-galactic people, that to propel the ship via one's own power, was too great a burden, for such long distances.
So instead, all they had to do was allow their ship to be pulled gravitationally by each large planet or sun roughly in the direction they wished to go. Then just before they crossed that critical threshold passed which they would be sucked into the denser gravitational power field of that planet/sun (read identity), they would refocus the ship to another planet/sun, and allow it to pull them towards it - till again, just before that critical threshold, they would re-focus again on another.
This way they used the innate attractive force of each object along their intended path, to 'pull' them through the universe, rather than self-power the whole way.
The trick was knowing when to pull out, before you inevitably donned the identity badge of the object - read group. By balancing alignment with the attractive forces in one's world, one is then able to borrow the enthusiasm of an object (like a job, a family, a nation, a religion, a sport club). That way we get to experience the world, pick out the juicy eyes of each passing energetic package, but always move on... forever moving on.
you should realise that underneath all this is a very dangerous message. It leads to becoming disconnected to our 'world' - esp our social world, but also our entire world of meaning. Juan once said, even his teachings to CC were folly. We cut ourselves off on a very deep level, till there is only one link left, our stem.
If you aren't ready for that adventure, best to go slowly, or not at all.
