Algebra, chapter II, § 1. Modules

For a family (at)t∈T(a_t)_{t \in T} of elements of an A-module E to be a generating system of E, it is necessary and sufficient that the linear mapping As(T)→EA_s^{(T)} \to E determined by this family be surjective.

This is just another way of expressing Proposition 9 of no. 7.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
