Abstract: The problem of social equality and social inequality is investigated in the light of the concept of justice, the concept of just inequality and unfair equality. The author substantiates the interrelation of justice and equality as concepts and phenomena that are presented in an indissoluble unity and are actually a two-pronged problem. Justice is interpreted by the author as a measure of social equality and social inequality. The author explores the problem of social inequality from the point of view of a materialistic understanding of history, the principle of development and an axiological approach. The concept of natural justice is investigated as the basis of justice established by people, that is, social justice. The legitimacy of the conditional use of the concept of natural justice as a natural right of an individual to use his natural gifts, which under certain conditions of social life activity can be decisive in human life, can give him fair advantages over other members of the society.
The natural personal potential of an individual can cause significant differences in the intellectual and spiritual abilities of people, which, in the presence of diligence, determination and appropriate social norms, necessarily generate social inequality in society. Fair inequality does not contradict natural justice. Natural justice is contradicted by unfair inequality. A person by nature has the right to life, freedom and property in compliance with the mandatory norms established in this society. Justice established by people should not contradict natural justice. The validity of the use of the concept of legitimate elite as the most outstanding personalities in various respects, having high achievements and services to society in various spheres of human activity, is substantiated.

Abstract: The article examines the main provisions of the idea of social justice in the philosophy of the famous Russian philosopher Vladimir Solovyov. His interpretation of the idea of justice is studied in the context of his understanding of such concepts as morality, kindness, mercy, altruism, compassion, etc. It is emphasized that in his works V. Solovyov pays special attention to the question of the relationship and interdependence of justice and morality. A socially just and moral society is considered by him as a possible future. The idea of social justice in the philosophy of V. Solovyov is studied as an original teaching in the light of the enrichment of this problem. The author considers the views of V. Solovyov as a reflection of the realities of modern Solovyov society and tries to identify ideas in it that can be used in the implementation of social justice in the conditions of modern realities.
The author explores the idea of justice in the philosophy of V. Solovyov in the context of the unity of all spheres of social life, causal and functional relationships, from the point of view of the relationship and interdependence of needs, interests, material and spiritual values. The interpretation of the idea of justice by V. Solovyov seems to the author interesting and original. This interpretation reflects the worldview of certain social strata of society and their wishes. His idea of justice has its absolute merits. The most interesting in the views of V. Solovyov is the provision according to which all the peoples of the world should have freedom of choice in terms of religion and religious orientation, proposals on the need for religious tolerance in society and in relations between peoples are interesting. The idea of social justice in V. Solovyov's philosophy requires further in-depth research in the context of current and subsequent social realities. At the same time, the author does not observe in the views of V. Solovyov the interrelation of the concepts of due and good, the interrelation of needs, interests and moral values.

Abstract: Separate issues of possible relations between generations in the context of the concept of social justice are investigated. Special attention is paid to the need to preserve the environment, natural resources, the preservation of life on earth, biological diversity, the need to search for alternative energy sources, to ensure favorable living conditions for future generations. The author draws attention to the theoretical difficulties in unambiguously defining the rights of future generations, to the difficulties of their legal formulations.
The author explores the problem of justice in relations between generations from the point of view of the materialistic understanding of history, the dialectic of social existence and social consciousness, the relationship of needs, interests and values, the principle of development and the principle of historicism.
The study of possible relations between generations in the context of the realities prevailing in the modern world contributes to the reassessment of the established values of modern society and the formation of a new worldview that takes into account the need to preserve peace, the cultural heritage of mankind, natural resources, human habitat, biological diversity, the transfer of resources to future generations. In this regard, there is a reassessment of the known norms of justice, morality and law. Modern interpretations of global problems, including issues of intertemporal justice, were a reflection of new historical realities. The creation of favorable conditions for future generations should not harm the necessary and reasonable needs of modern society.

Abstract: The article explores the main ideas of the concept of justice by John Locke, one of the most prominent representatives of the social and political philosophy of Modern times. The article considers the contractual theory of the origin of the state and the concept of justice in the context of the relevance of the realities of the modern world. D. Locke's concept of justice is investigated in the light of the enrichment of this problem. The author considers D. Locke's views as a reflection of the realities of social life of this era and tries to identify in them ideas that can be used in the realization of justice in modern society.
The author explores D. Locke's concept of justice from the point of view of a materialistic understanding of history, the unity of various spheres of public life, the relationship of causal and functional relationships, in the context of the dialectic of economics and politics, from the point of view of the relationship and interdependence of needs, interests and moral values. The concept of D. Locke is considered as a pronounced contractual theory. The socio-political views of D. Locke in the light of the concept of justice seem interesting and original. The concept of D. Locke has its merits, for example, the position on the priority of the idea of the public good over the private selfish interests of an individual, the position on the need to correspond to the mind of individual interests and freedom. The unconditional merits in his research can be attributed to the further enrichment of contractual theory, his interpretation of the concept of fair equality and property rights. This interpretation was a reflection of new historical realities. D. Locke's ideas remain relevant in the context of modern socio-political realities and require further research.
