In this article the author argues that solidarity can be used as an analytical concept in order to understand the dynamics of discourses in the public spheres of contemporary democracies. He begins by discussing conceptions of solidarity in political theory, followed by descriptions of its manifestations in recent public debates in different countries. After that, he relates solidarity to Habermas’s formal-pragmatic concept of communicative rationality, which enables him to sketch out notions such as discursive and selective solidarity, as well as discursive modulations of solidarity, which are formulated through analogies of discourse theory and musical theory. In the last part of the article, the author applies these notions to three specific examples of public debates in the Brazilian public sphere.

在本文中，作者认为团结可以用作一种分析概念，以便理解当代民主国家公共领域话语的动态。他首先讨论了政治理论中的团结概念，然后描述了最近在不同国家进行的公开辩论中其团结的表现。之后，他将团结与哈贝马斯的交际理性的正式语用概念联系起来，这使他能够勾勒出话语理论和音乐理论的类比，从而形成了话语和选择性团结以及对话语的调性调制等概念。在文章的最后部分，作者将这些概念应用于巴西公共领域公共辩论的三个特定示例。
