Derrida in conversation with Maurizio Ferraris, translated by Giacomo Donis in I Have a Taste for the Secret (2001):
I have a taste for the secret, it clearly has to do with not-belonging; I have an impulse of fear of terror in the face of a political space, for example, a public space that makes no room for the secret. For me, the demand that everything be paraded in the public square and that there be no internal forum is a glaring sign of the totalitarianization of democracy. I can rephrase this in terms of political ethics: if a right to the secret is not maintained, we are in a totalitarian space.
Belonging—the fact of avowing one’s belonging, of putting in common—be it family, nation, tongue—spells the loss of the secret.
