This paper answers Adorno's question, once asked in a lecture, about whether we, by forbidding the thought of the non-identical, fall in radically completed enlightenment back into the darkest form of mythology. In arguing for this in the question implied observation of enlightenment's fallback, the paper analyses Adorno's and Horkheimer's critique of enlightenment and its relapse due to excluding the non-identical, suggesting that emotions and memory represent this non-identical. As the darkest form of mythology Adorno is referring to is not (...) to be understood as a myth itself but actually happened with the Holocaust, the paper then demonstrates how enlightenment, chiefly its exclusion of the non-identical, led to central conditions of the Holocaust that Adorno named ‘Auschwitz’. As enlightenment, according to Adorno, remains in its relapse, the paper finally discusses how his philosophy after Auschwitz advocates for the reintegration of the non-identical, mainly through the recollection of the past and the remembrance of nature within the subject.
