"It is once again the vexing problem of identity within variety; without a solution to this disturbing problem there can be no system, no classification"

This quote by Roman Jakobson speaks with the trouble of producing a system or category when faced with a range of identities. It suggests that without a service to the issue of identity within range, it is difficult to produce a system or classification. This is due to the fact that the variety of identities present in any given scenario can make it difficult to create a system that is both extensive and accurate. Jakobson's quote highlights the complexity of producing a system or category when confronted with a variety of identities, and recommends that without an option to this problem, it is difficult to develop a system or classification. This quote talks to the problem of creating a system or classification that is both detailed and precise, and highlights the importance of discovering a solution to the vexing problem of identity within variety.
