At a recent Brunch Talk, Olivier Lembcke offered an in-depth exploration of democratic theory, focusing on the distinction between “thin” and “thick” concepts of democracy and the critical role of political parties in maintaining democratic life.

Lembcke explained that the “thin” concept of democracy highlights the procedural framework that makes a system democratic, including structures such as elections, voting, and the rule of law. In contrast, the “thick” concept goes further, stressing substantive elements such as active participation and the degree to which democracy fosters a just society.

He emphasized that representative democracies rely heavily on political parties, which not only function as administrative apparatuses but also as social movements and vehicles for elected representatives. Operating across these three levels, parties play a decisive role in shaping the quality of democracy. According to Lembcke, they must continuously balance the relationship between the electorate and the government, a challenge that defines both their strength and their long-term success.
