The representative institutions of democratic government require the public sphere; but this in turn rests on the fellow‐feeling of citizens. In this article, I explore some recent ways of fleshing out Mill’s thought that patriotic fellow‐feeling is instrumental for a form of trust that the public sphere requires. Deliberation, argument and negotiation in the public sphere require a willingness to discuss, alter one’s position, compromise with others, and do so in good faith and in the belief that other participants are (...) broadly also taking part in the same fashion. Since politics is a realm in which interests and identities clash, we have at least a prima facie reason to worry that others may in fact not be trustworthy in the desired way. Some potential for distrust is inherent in political deliberation, since it presupposes that there is some important conflict or disagreement that needs to be overcome through discussion: in other words, that I cannot simply rely on others to further my interests for the right reasons, or at all. While trust seems inherently problematic, political dialogue in the public sphere seems to require it from those who take part. I look at four accounts of the basis of democratic trust, viz. the communitarian, the ‘societal culture’ account, the public culture account, and what is known as the ‘constitutional patriotism’ account. In outline, my argument is that all four accounts fail to explain the basis of trust in the democratic sphere. I conclude that sharing a national identity still leaves the politics of trust to be negotiated by the participants concerned. (shrink)
