"...we have to recognise the positivity of difference. There is no origin (such as consciousness) that must negate the world, for consciousness must already be differentiated. Difference is therefore not grounded on anything other than itself. It is only through difference that we can think of any origin, including consciousness....The differences of a language produce meanings, produce consciousness or produce our world. These language differences are in themselves meaningless: the sounds of our language are so much noise, script so much material marking. But sound and script make sense because they are systemised, repeated and exchanged. We use a word not because we grasp some mental event of the speaker, but because we also use, exchange and repeat the same system. When we 'translate' from one language into another, we move from one set of differences into another. "
