Silo travelled around Argentina, South America and Europe and undertook various jobs. By 1960 – following "a rearrangement of his inner truths" as a newspaper slogan of the time reported – he began to present his proposals, while still forming study groups in Argentina and Chile. With members of these groups he organized a public talk, which was initially banned by the military government but later was permitted in the mountains, away from the centres of population. The military dictatorships which subsequently beset the country were present throughout the life of Silo with successive arrests and detentions.
