Integration, chapter IX, § 6. Promeasures and measures on a locally convex space

— When EE is finite-dimensional, every character of EE is of the form x↦ei⟨x,x′⟩x \mapsto e^{i\langle x, x' \rangle} with x′∈E′x' \in E' (Théor. spect., Ch. II, §1, No. 9, Cor. 3 of Prop. 12). In this case, Prop. 3 follows from the uniqueness theorem for the Fourier transformation (loc. cit., §1, No. 6, Cor. of Prop. 6).*

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