The essays are meant to give some ideas for the discussions we have. That is, if people feel like using them that way. I also use these essays to express some of my ideas and thinking on the subject.
However, because I usually write these essay at short notice, I have no time to do in depth research on the subject. And any ideas I feel are my own, might have already been expressed by others. But I did not come across them in the limited research I some times do.
Finally, most times I do not have time to polish my essay as they ought to be. I apologise for this.
