Robert Goodin claims that he has undermined my ``proof of theinevitability of rational consensus among all patient people of goodwill.'' I did not intend my position as a proof of the inevitabilityof rational consensus, however, and, in fact, I insist on thereasonableness of dissensus in some cases. I welcome the opportunity,provoked by Goodin's interesting reflections, to clarify my position. Iproved with Carl Wagner that iterated weighted averaging converges towardconsensus under conditions of connectedness and constancy resulting fromthe positive weight that individuals give to each other. I allow, nevertheless,that individuals may rationally assign zero weight to each other in a waythat blocks convergence and yields dissensus. The assignment of zeroweight to others will be rational, for example, when the interests ormoral concerns of the individual would be co-opted as a result of givingpositive weight to others. The assignment of positive weight to othersrequires modification of one's position, however, for the refusal to modifyone's position is mathematically equivalent to assigning zero weight toothers. Dissent is rational to avoid being co-opted, but the cost ofdisensus may be the assignment of zero weight to others and theirrational reciprocation.
