Inquiry into the philosophy of Derrida

In class we discussed Jacques Derrida and his belief that language has always been there, since before we were born. It is not something we create, but something in us. This is interesting because it makes me wonder if words have any meaning without a reader. If I wrote a book tomorrow and the next day the sun went out and no one could see or read, would my story have any less importance? It might have none. It might even mean that the story did have meaning in a past world, lost with the light of the sun. Or, perhaps it would be good for starting a fire.
