For Freire, solidarity as an act of support leads people starting from different ideological standpoints and using different paths.

The essential common trait in all instances is the support for the oppressed in everything they need – both in "a glass of water" and in the political struggle against the violation of their rights, against exploitation, discrimination, racism, and social exclusion.

In this sense, the act of solidarity can function as a binding thread among people who have different opinions on a variety of other issues.

This belief, which characterizes his life and permeates his entire work, is perhaps the most significant message of this book to those who struggle for a truly humane society.
