Ronnie Brown: from Esquisse d’un Programme by A Grothendieck

I just came across again the following (English translation):
 The demands of university teaching, addressed to students (including
those said to be “advanced”) with a modest (and frequently less than mod-
est) mathematical baggage, led me to a Draconian renewal of the themes
of reflection I proposed to my students, and gradually to myself as well.
It seemed important to me to start from an intuitive baggage common to
everyone,  independent of any technical language used to express it,  and
anterior to any such language
– it turned out that the geometric and topo-
logical intuition of shapes, particularly two-dimensional shapes, formed such
a common ground.
(my emphasis)
It seems to me a good idea, and expressed with AG’s usual mastery of language.
Ronnie
