They do not know that dream is a constant of life so concrete and defined as any other thing, […] They do not know, neither dream, that dream commands life. That whenever a man dreams the world jumps and advances like a colourful ball between the hands of a child.

Excerpt of the poem Philosophal Stone by António Gedeão,
In Perpetual Movement, 1956. Coimbra: Of. Atlântida
