How can we make the decade 1965-1975 come alive again, how can we highlight what was at stake in the world and in France, its scope, our commitment, our activist universe? Through analysis certainly, but reinforced by lived experience, which is necessarily more personal. This is a delicate exercise, with a constant coming and going between general considerations, the transmission of a political history that is sometimes specific (that of my political current) and its individual, daily implications. To this end, I am mobilizing my own memories - and I am wary of memory and especially of mine, which I know is incomplete. I am therefore appealling for a confrontation of recollections (or archives) that could lead me to correct or qualify some of my remarks.
