"At some point we will have to decide whether Hebrew in the next thirty or three hundred years will serve merely as a channel of immediate and basic communication, as a language at the top of a pyramid, without any pyramid beneath it, a claustrophobic language not much different from Esperanto, or whether it will embody an entire non-Western culture that we know is worth preserving. Since language shapes us more than we shape it, this decision will be essentially about our own identity. It seems more and more certain that this will be a matter of a conscious decision."
