He is part of a tradition of visionary thought that includes Father António Vieira and the poets Luís de Camões and Fernando Pessoa. Like Joachim de Fiore, he speaks of the coming of one (last?) age in History, the Age of the Holy Spirit, in which mankind and society attain perfection.

It also means that the nature of mankind and the nature of God will become the same. In this sense his philosophy is both an eschatology and an utopy.
