From the article SOLIDARITY, published in Regeneración, October 29, 1910
"Solidarity is the consciousness of the common interest, and the actions that follow from this consciousness."
"Ignorance of humanity's common interest, that is, ignorance of solidarity, makes each man see in the other man a competitor who must be vanquished so that he can live."
"One must consider an injury to one an injury to all."
- Ricardo Flores Magón
