The different pages of this site

The site contains a limited number of main pages. This choice is intended to facilitate the first reading. However, all important notions and expressions give access to other pages, comments or definitions, which you can reach by clicking on the highlighted words.

Highlights appear in the text if you pass the cursor over the commented words or passages, then just click to make the comment appear. You can also click on the button at the top of the page to make the highlight appear, and lock them if that is your preference.
