We do things differently around here. (Or rather, we like to think we do.) The South African Institute for Advanced Constitutional, Public, Human Rights and International Law (SAIFAC) opts for seminar formats that place individuals in conversation with one another – in a manner that is rigorous yet collaborative, spirited rather than competitive. One result of this methodology is this book. Professor Frank Michelman neatly captures the book’s ethos: ‘Our aim is to learn: aggressively to learn what there is to be learnt from puzzles our interlocutors pose to us, by assuming there is method in their madness and doing our best to ferret that out, using everything else we know or can guess (in part from their likeness and kinship to us) about where they are coming from.’ The purpose in crediting our interlocutors is to sharpen the critical bite of outstanding differences. Sometimes a pair of conversants will even wind up singing off the same hymn sheet. Whatever the outcome, it’s safe to say that each presenter in this series has been forced to rethink her or his initial position. O dialogo continua!!
