In fact, Whitehead describes any entity as in some sense nothing more and nothing less than the sum of its relations to other entities – its synthesis of and reaction to the world around it. A real thing is just that which forces the rest of the universe to in some way conform to it; that is to say, if theoretically a thing made strictly no difference to any other entity (i.e. it was not related to any other entity), it could <answer>not be said to really exist.</answer> Relations are not secondary to what a thing is, they are what the thing is.
If an object made no difference to any other entity, what could be said about it?
