Algebra, VIII, p. 154, § 9. Radical

The Jacobson radical (or simply radical) of a ring A, denoted by R(A)\mathfrak{R}(A), is the radical of the A-module AsA_s, that is, the intersection of the maximal left ideals of A.

By abuse of language, we say that the ring A is without radical if we have R(A)=0\mathfrak{R}(A) = 0.

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
