In Hobbes, freedom of choice requires nonfrustration: the option you prefer must be accessible. In Berlin, it requires noninterference: every option, preferred or unpreferred, must be accessible—every door must be open. But Berlin’s argument against Hobbes suggests a parallel argument that freedom requires something stronger still: that each option be accessible and that no one have the power to block access; the doors should be open, and there should be no powerful doorkeepers. This is freedom as nondomination. The claim is that freedom as noninterference is an unstable alternative between freedom as nonfrustration and freedom as nondomination.

Taken as a model for how groups should make collective judgments and decisions, the ideal of deliberative democracy is inherently ambiguous. Consider the idealised case where it is agreed on all sides that a certain conclusion should be endorsed if and only if certain premises are admitted. Does deliberative democracy recommend that members of the group debate the premises and then individually vote, in the light of that debate, on whether or not to support the conclusion? Or does it recommend that members individually vote on the premises, and then let their commitment to the conclusion be settled by whether or not the group endorses the required premises? Is deliberative democracy to enforce the discipline of reason at the individual level, as in the first possibility, or at the collective level, as in the second?

A generation of social theorists have argued that if free-rider considerations show that certain collective action predicaments are unresolvable under individual, rational choice – unresolvable under an arrangement where each is free to pursue their own relative advantage – then those considerations will equally show that the predicaments cannot be resolved by recourse to norms (Buchanan, 1975, p. 132; Heath, 1976, p. 30; Sober and Wilson, 1998, 156ff; Taylor, 1987, p. 144). If free-rider considerations explain why people do not spontaneously keep the streets clean, though they would each prefer unlittered streets, then those considerations will also explain why there is no effective norm against littering the streets.
