The name Fundação PI carries three layers of meaning. In mathematics, pi relates a circle to its own measure, a constant without end. The circle is among the oldest symbols of wholeness: metaphysically it stands for unity, socially for the gathering of equals around a shared center. In Portuguese, PI abbreviates “Porque Importa,” because it matters, naming the foundation's reason for acting before any strategy does.

The effective exercise of citizenship, political participation and respect for Human Rights are more than mere legal abstractions — they depend on basic biopsychosocial conditions of dignity. Chronic stress arising from housing and financial scarcity alters brain function, limits prosocial decision-making and amplifies reactive behaviour. Our Foundation was established to demonstrate, with scientific rigour, that by guaranteeing housing and economic stability, we disarm the biological mechanisms of exclusion. We free the social brain for empathy, literacy and community building.
— Mariline Gomes da Silva Cristóvão
Driven by this conviction, I decided to devote part of my time and resources to actively supporting the defence of Human Rights. This philanthropic initiative aims to support people, causes, communities and organisations that work every day for greater justice, protect the most vulnerable and promote equal opportunities. I invite everyone who shares this vision to join this reflection and action. Together, we have the power and the responsibility to build a fairer and more humane world.
