DISCUSSION: There was no formal discussion, although many members made comments and asked questions about various aspects of the paper. Dr. Heinz Hartmann expressed his general agreement that the degree or range of neutralization is difficult to quantify and cannot be explained completely by the economic approach. He wished to state, however, that neither he nor Kris believes that sublimated activities are the expression of the highest degree of neutralization. Nor does Dr. Hartmann feel that the maximum of neutralization is optimal. He essentially agrees with the author that the degree of neutralization is optimal for the function to which it is geared.
