The problem of the relation of a single and multiple

In this paper, we consider the problem of the ratio of single and multiple. The concepts of "single" and "plural" are rather abstract. The one is the absolute, which does not depend on anything, while all other existence depends on it. The whole is a certain set, representing a unity, or some unity, which is a set. In conclusion, it is told that the plural are people, and the single is what unites them in one whole: the language in which they all speak, a single religion, common views on life, common interest.
