Depression isn't just being a bit sad. It's feeling nothing. It's not wanting to be alive anymore.
[Photography] allows me to accede to an infra-knowledge; it supplies me with a collection of partial objects and can flatter a certain fetishism of mine: for this 'me' which like knowledge, which nourishes a kind of amorous preference for it. In the same way, I like certain biographical features which, in a writer's life, delight me as much as certain photographs; I have called these features 'biographemes'; Photography has the same relation to History that the biographeme has to biography.
