I am, because we are; and since we are therefore I am.
John Mbiti (1969): African Religions and Philosophy. Nairobi: East African Educational Publishers, p. 106
John Mbiti (1931-2019) was a Kenyan theologian. This quote is based on Ubuntu philosophy which has spread across many parts of Africa, e.g. in Zulu: ‘Umuntu ngumuntu ngabantu’ (A man is a man through other men).

Ubuntu gets applied to many fields that include philosophy, a freely available computer operating system, and as an inspiration for an economic system beyond capitalism. In contrast to Descartes' cogito ergo sum (I think, therefore I am), this attitude of mind shows that unlike in the Enlightenment’s individualistic world view, people’s well-being is interlinked. It follows that success is therefore not the accumulation of material wealth by individuals, but the ‘
restoration of vitality, the living spirit that permeates our existence and the world of which we are a part’ (Naudé 2010: 113). Naudé, a professor at Nelson Mandela University in South Africa, suggests that African Ubuntu philosophy could be the basis for a new trading system.

Descartes was wrong: ‘a person is a person through other persons’.
