Light (1919), Ch. XX The Cult
Context: The idea of motherland is not a false idea, but it is a little idea, and one which must remain little.
There is only one common good. There is only one moral duty, only one truth, and every man is the shining recipient and guardian of it. The present understanding of the idea of motherland divides all these great ideas, cuts them into pieces, specializes them within impenetrable circles. We meet as many national truths as we do nations, and as many national duties, and as many national interests and rights — and they are antagonistic to each other.

“I sell an idea, an idea in a can.”
Quote of Manzoni, (refering to his art-work in 1961 'Artist Shit'); as cited on 'Heart', in the aricle 'More about Piero Manzoni' http://www.heartmus.dk/en/about-heart/our-collection/piero-manzoni/more-about-piero-manzoni.html

“Truth is the agreement of our ideas with the ideas of God.”

“A god is the idea of a god. The idea of a god is a god.”
De Abaitua interview (1998)
Context: A god is the idea of a god. The idea of a god is a god. The idea of Glycon is Glycon, if I can enhance that idea with an anaconda and a speaking tube, fair enough. I am unlikely to start believing that this glove puppet created the universe. It’s a fiction, all gods are fiction. It’s just that I happen to think that fiction’s real. Or that it has its own reality, that is just as valid as ours. I happen to believe that most of the important things in the material world start out as fiction. That everything around us was once fiction – before there was the table there was the idea of a table, and the idea of a table before tables was fiction. This is the most important world, the world of fictional things. That’s the world where all this starts.
