Blog and opinion republishing

I used to have personal webpages, opinion pages, archived scientific and philosophic correspondence, even blogs on the web on various periods but most of them are now unreachable, deleted or non editable. This forms what I use to call volume XVI of my collected works (volume XIV being notes taken during seminars and lectures, volumes XIII being postal correspondance). All the posts in this blog with a date before April 1st 2010 are republications of previous contributions of this kind. New information or new ideas added after the original publication will be outlined with the date.
