Be that as it may it s still a preface and prefaces are ultimately works of puffery They are not independent third party sources at all If Pons thought Polak s work was so wonderful I have to ask why he didn t write a review for Le Monde In my view most prefaces are the equivalent of someone putting testimonials on a business website It s always good to get named people because it makes the business like the author somehow look better In any case it should be removed definitely from the lead and put in a lower part of the text if at all Currently it s misleading to open the article with that citation
