In mathematics particularly set theory , a finite set is a set that has a finite number of elements. Informally, a finite set is a set which one could in principle count and finish counting.

In set theory , an ordinal number , or ordinal , is one generalization of the concept of a natural number that is used to describe a way to arrange a possibly infinite collection of objects in order, one after another. Any finite collection of objects can be put in order just by the process of counting: labeling the objects with distinct natural numbers. The basic idea of ordinal numbers is to generalize this process to possibly infinite collections and to provide a "label" for each step in the process. Ordinal numbers are thus the "labels" needed to arrange collections of objects in order. An ordinal number is used to describe the order type of a well-ordered set though this does not work for a well-ordered proper class.

## Why Numbers Are Sets

This entry focuses on the axiomatisation; a further entry will consider later axiomatisations of set theory in the period —, including Zermelo's second axiomatisation of The introduction to Zermelo's paper makes it clear that set theory is regarded as a fundamental theory:. Zermelo goes on:. In solving the problem [this presents] we must, on the one hand, restrict these principles [distilled from the actual operation with sets] sufficiently to exclude all contradictions and, on the other, take them sufficiently wide to retain all that is valuable in this theory. Perhaps the best way to state the suggested solution [of the Russell-Zermelo contradiction] is to say that, if a collection of terms can only be defined by a variable propositional function, then, though a class as many may be admitted, a class as one must be denied.

I follow standard mathematical practice and theory to argue that the natural numbers are the finite von Neumann ordinals. I present the reasons standardly given for identifying the natural numbers with the finite von Neumann's e. Natural numbers are sets. They are the finite von Neumann ordinals.

Она вглядывалась в глаза Танкадо - и видела в них раскаяние. Он не хотел, чтобы это зашло так далеко, - говорила она.  - Он хотел нас спасти. Но снова и снова он протягивал руку, так, чтобы люди обратили внимание на кольцо. Он хотел объяснить им, но не .

Халохот приблизился к внешней стене и стал целиться. Ноги Беккера скрылись из виду за поворотом, и Халохот выстрелил, но тут же понял, что выстрел пришелся в пустоту. Пуля срикошетила от стены. Рванувшись вниз за своей жертвой, он продолжал держаться вплотную к внешней стене, что позволило бы ему стрелять под наибольшим углом.
