Of course she is. She is an American actor who played Rachel in Friends.
But there is another Jennifer Aniston: the Jennifer Aniston represented in my pattern of neural activity through which I recognize, remember and imagine her. Experiments with so-called “concept cells” have even found individual neurons that respond selectively when a person is shown or thinks about a particular individual.
And then there is a third Jennifer Aniston.
Not the woman herself,and not my neural representation of her, but the “culturally transmitted pattern”: the network of images, names, descriptions, stories, associations and references through which Jennifer Aniston can be represented and communicated between minds.
This Jennifer Aniston isn’t located in any one brain. She is instantiated in brains, photographs, films, books, conversations and other media. Those instances allow the pattern to be transmitted, modified and reconstructed.
So in what sense is this third Jennifer Aniston real?
She is not an additional physical object hiding somewhere behind the photographs and neurons. Yet she is not simply imaginary either. She is a pattern with physical instantiations and real causal effects.
Perhaps, then, reality isn’t restricted to things. Perhaps patterns can be real too.
If Jennifer is real, is love also real?
