Plato's
Tetralogies 
The array below presents the suggested organization of the dialogs in seven tetralogy, one by line of the array. For each tetralogy, the first column lists the "introductory" dialog, and the next three colums list the associated trilogy. From there, you can get to a general comment on the organization of the tetralogies (Overview of Tetralogies), or to comments on individual tetralogies or dialogs.
Note: in this array, only the tetralogies and dialogs for which a comment is currently available, in full or in part, show up as links. As new comments are made available, all titles should eventually become links.
