An alternate method is described to extract the quark contribution to the spin of the nucleon directly from the first moment of the deuteron structure function, g^d_1. It is obtained without recourse to the use of input on the nucleon wave function from hyperon decays involving the flavor symmetry parameters, F and D. The result for the quark polarization of the nucleon, ΔΣ_ N, is in good agreement with the values of the singlet axial current matrix element, a_0, obtained from recent
