“We sift reality through screens composed of ideas. (And such ideas have their roots in older ideas.) Such idea systems are necessarily limited by language, by the ways we can describe them. That is to say: language cuts the grooves in which our thoughts move. If we seek new validity forms (other laws and other orders) we must step outside language.”

Context: It is often said that experiments should be made without preconceived ideas. That is impossible. Not only would it make every experiment fruitless, but even if we wished to do so, it could not be done. Every man has his own conception of the world, and this he cannot so easily lay aside. We must, for example, use language, and our language is necessarily steeped in preconceived ideas.

De Abaitua interview (1998)
Context: As I understand, or as I hallucinate conceptual space, nearly all form in conceptual space is language, I might even say all the form in non-conceptual space is language, I’m not even sure of what the difference between physical space and conceptual space is anymore, in the interface. All form is language. The forms that we see, or imagine, or perceive, or whatever it is Remote Viewers are doing, in conceptual space are mindforms made from language, and by language I also mean images, sounds. We dress these basic ideas in language we can understand. Sometimes there are sizable errors of translation.

Context: Our ability to destroy ourselves is the mirror image of our ability to save ourselves, and what is lacking is the clear vision of what should be done... What needs to be done is that fundamental, ontological conceptions of reality need to be redone. We need a new language, and to have a new language we must have a new reality... A new reality will generate a new language, a new language will fix a new reality, and make it part of this reality.
