Concerning the remark "on spite of the advice of Grothendieck"
(that I concluded following some readings I do not remember where, and
that if I remember correctly, Grothendieck wanted to rewrite the whole
project (before it was published) using Category Theory, and presented a
proposal that after some consideration was turned off by Bourbaki)
I received a private mail that can be of interest to many and that I
copy and paste below:
===================================================================
Pierre Cartier, Chritian Houzel, Andrej Rodin and Ralf Krömer wrote
about that issue.
You will find the source material, i.e. the early Bourbaki archives
(1934-1954), which show various early attempts at defining "structure",
online at http://mathdoc.emath.fr/archives-bourbaki/
A bibliography of sources on Bourbaki is at
http://poincare.univ-nancy2.fr/Actu/?contentId=9473
One may not confuse any edition of the first volume of the Elements with
Bourbaki relatively evolving thoughts on this matter.
There is a lot to be learnt from reading the sources. Please notice that
I replied to you personally and not to the whole list. Be kind to a shy
person. Best regards, LB
