Essays are wonderful, and simultaneously very difficult to write, for the same reason: one can write about anything, but not everything. There is freedom in the abscence of plot, story or characters one has to keep track of in fictitious story, but with this freedom all the distractions and decorations are stripped off as well. The essay should explore one topic or thought to the furthest extent and stay as sharp and concise as possible.

This brings me to the point: writing a good essay is very hard and takes a crystal clear understanding of the subject along with writing skills. And reading one is a delight and an intellectual challenge. If you have any good essays on your mind, ideally on the topics of science and technology, but other domains will do as well - please tag me. In return I suggest you "Cinque scritti morali", or "Five Moral Pieces" as an entertaining read, by Umberto Eco.
