One of the classical results of ring theory is due to Levitzki ((3), p. 199) and asserts the equivalence of the notions of nil and nilpotent one-sided ideals in a ring satisfying the ascending chain condition on left ideals. Recent, distinctive proofs of this result have been given by Goldie (1) and Herstein (2). We present below yet a fourth way of proving Levitzki's theorem.
