Here, by class I simply understand the extension of some predicate. Due to Russell\u2019s paradox, the naive comprehension schema is inconsistent. The orthodox solution to the class-theoretic paradoxes is found in the theory of types. However, this theory comes with severe expressive limitations, e.g. there can be no universal class (i.e. a class containing all objects). Based on some ideas of G\u00f6del, I present a type-free theory of classes according to which there is a universal class containing all objects, including itself. I have published the basic ideas of my theory in my paper <a href=\"https:\/\/doi.org\/10.1007\/s11098-017-1022-2\">\u201cClasses, why and how\u201d (Phil Studies 2019)<\/a>.
