Brazil's former President Luiz Inacio Lula da Silva, in a letter to the 8th Conference of the Latin American Council of Social Sciences (Clacso), affirmed that "another world is possible and necessary."
In the letter, Lula states that he is convinced that "at a time when part of Latin America and the world is experiencing the rise of backwardness; of lies, now called 'Fake News;' of political violence; and judicial persecution... that another world is possible and necessary."
The Workers Party veteran - who remains imprisoned over the past seven months - for alleged acts of corruption, acknowledges solidarity of his supporters, and express regrets at not being able to attend the conference - which will be attended by some 50,000 delegates from across 50 countries.
The Clacso conference, which takes place in Argentina, allows politicians, intellectuals, activists, and students to analyze issues such as global geopolitics, climate change, environmental governance and other challenges of popular movements.
The meeting has become a valuable space for critical thinking as well as a platform for activists, who fight for a better world, and others who seek alternatives to neoliberalism and capitalism.
Clacso - established in 1967 - is an international non-governmental institution that brings together 624 research and postgraduate centers in the field of social sciences and humanities in 47 countries.
Political figures, such as Argentina's former President Cristina Fernandez, Brazil's former President Dilma Rousseff, Colombia's former President Ernesto Samper, Bolivia's Vice President Alvaro Garcia Linera and Nobel Peace Prize winner Adolfo Perez Esquivel are expected to attend the conference.
