“Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe.”

Introduction to Blast Off : Rockets, Robots, Ray Guns, and Rarities from the Golden Age of Space Toys (2001) by S. Mark Young, Steve Duin, Mike Richardson, p. 6; the quote on hydrogen and stupidity is said to have originated with an essay of his in the 1960s, and is often misattributed to Frank Zappa, who made similar remarks in The Real Frank Zappa Book (1989): "Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe."
Context: NO ONE GETS OUT OF CHILDHOOD ALIVE. It's not the first time I've said that. But among the few worthy bon mots I've gotten off in sixty-seven years, that and possibly one other may be the only considerations eligible for carving on my tombstone. (The other one is the one entrepreneurs have misappropriated to emboss on buttons and bumper stickers: The two most common elements in the universe are hydrogen and stupidity.
(I don't so much mind that they pirated it, but what does honk me off is that they never get it right. They render it dull and imbecile by phrasing it thus: "The two most common things in the universe are..."
(Not things, you insensate gobbets of ambulatory giraffe dung, elements! Elements is funny, things is imprecise and semi-guttural. Things! Geezus, when will the goyim learn they don't know how to tell a joke.

Context: The current worldview has it that everything is made of matter, and everything can be reduced to the elementary particles of matter, the basic constituents — building blocks — of matter. And cause arises from the interactions of these basic building blocks or elementary particles; elementary particles make atoms, atoms make molecules, molecules make cells, and cells make brain. But all the way, the ultimate cause is always the interactions between the elementary particles. This is the belief — all cause moves from the elementary particles. This is what we call "upward causation." So in this view, what human beings — you and I think of as our free will does not really exist. It is only an epiphenomenon or secondary phenomenon, secondary to the causal power of matter. And any causal power that we seem to be able to exert on matter is just an illusion. This is the current paradigm.Now, the opposite view is that everything starts with consciousness. That is, consciousness is the ground of all being. In this view, consciousness imposes "downward causation." In other words, our free will is real. When we act in the world we really are acting with causal power. This view does not deny that matter also has causal potency — it does not deny that there is causal power from elementary particles upward, so there is upward causation — but in addition it insists that there is also downward causation. It shows up in our creativity and acts of free will, or when we make moral decisions. In those occasions we are actually witnessing downward causation by consciousness.
