Quite often we hear about issues with “identity politics”, but what about ‘identity’ itself? In a recent episode of ‘The Philosopher’s Zone’ Laurance Splitter and Laura D’Olimpio discuss this. In particular, a distinction is made between a strict or quantitative notion (briefly stated as what makes something or someone unique) and a looser notion, qualitative and somewhat colloquial, yet in some ways more socially relevant. This second notion relates not to what is unique, but what is similar (i.e. by what attributes can people or things be categorized together). There is a tension here, which has analytic and social implications.
Philosopher’s zone is a great podcast, and the entire series (which is quite large) is publically available. It’s a tremendous resource.
