Types are 'ramified' when there are further differences between the type of quantifier and its range [Linsky,B]
The ramified theory subdivides each type, according to the range of the variables [Linsky,B]

For those who abandon logicism, standard set theory is a rival option [Linsky,B]
Extensionalism means what is true of a function is true of coextensive functions [Linsky,B]
Higher types are needed to distinguished intensional phenomena which are coextensive [Linsky,B]
The task of logicism was to define by logic the concepts 'number', 'successor' and '0' [Linsky,B]
