Is naive set theory, simply set theory that has been left unformalised as the entry in Wikipedia suggests? One example is Russell’s Paradox, also known to Zermelo: consider the property of sets of not being … If R is not a member of itself, then its definition dictates that it must contain itself, and if it contains itself, then it contradicts its own definition as the set of all sets that are not members of themselves. Set theory is the most fundamental part of mathematics. Set theory is often viewed as the ``mother of all mathematics''. Much mathematics can be cleanly and axiomatically developed beginning with axiomatic set theory and then associating axiomatic rules to suitably defined sets and constructive relations. Sets count as objects. naive set theory in English translation and definition "naive set theory", Dictionary English-English online. Any two sets containing precisely the same members are the same set (Principle of Extensionality). For example, spam filters Email app uses are built on Naive Bayes. naive set theory.

The definition of almost any kind of mathematical object (a group, a ring, a vector space, a topological space, a Hilbert space...) begins: a consists of a set, together with some extra structure in the form of operations, relations, subsets, sets of subsets, functions to the real numbers, or whatever. However, the SEP, in its entry on inconsistent mathematics, suggests that:. Naive Set Theory is a mathematics textbook by Paul Halmos originally published in 1960.
