Ubuntu is a concept of southern African and specifically Nguni origin, usually conveyed through the maxim umuntu ngumuntu ngabantu, a person is a person through other persons. Its claim is that personhood is constituted relationally: one becomes fully human through community, recognition and participation, rather than possessing humanity as an isolated individual and then entering society with it.
The word is an ordinary Nguni noun meaning humanness, and cognate terms exist across a wide range of Bantu languages, botho in Sotho-Tswana, hunhu in Shona. In everyday use its content covers generosity, hospitality, compassion, respect and communal solidarity, and the sharpest available reproach in these terms is that a person has no ubuntu.
Its public prominence is recent and largely South African. It was taken up during the transition from apartheid and appeared in the epilogue to the interim Constitution of 1993, which spoke of a need for understanding rather than vengeance, for reparation rather than retaliation, and for ubuntu rather than victimisation. Desmond Tutu invoked it repeatedly in connection with the Truth and Reconciliation Commission, offering it as the ground for a restorative rather than a retributive approach to the past, and the Constitutional Court has referred to it in judgments, notably in the 1995 decision abolishing the death penalty. It has since been taken up in African philosophy, in theology, in management and leadership literature, and as the name of a widely used computer operating system.
It is genuinely contested, on several distinct grounds. Philosophically, Mogobe Ramose and others have developed it into a systematic African philosophy, while other African philosophers have questioned whether a proverb can carry that weight. Critically, it has been argued that ubuntu can subordinate the individual to the group and be used to suppress dissent; that its emphasis on reconciliation functioned in post-apartheid South Africa to limit accountability and material redress; and that its rapid commercialisation in corporate and Western self-help settings has hollowed it out. Some scholars have argued that the modern formulation is substantially a twentieth-century construction, drawing on genuine linguistic and social material but shaped by the political needs of a particular moment. Defenders reply that political concepts are always articulated when they are needed, and that the relational anthropology underlying the maxim is well attested across the region long before anyone had a use for it in a constitution.
