Pharmakos - a purification ritual

From Wikipedia :

In ancient Athens, the ritual of the pharmakos was used to expel and shut out the evil (out of the body and out of the city). To achieve this, the Athenians maintained several outcasts at public expense. In the event of any calamity, they sacrificed one or more than one outcasts as a purification and a remedy. The pharmakos, the 'scapegoat', the 'outsider' was led to the outside of the city walls and killed in order to purify the city's interior. The evil that had infected the city from 'outside', is brought out and returned to the 'outside', forever. But, ironically, the representative of the outside (the pharmakos) was nonetheless kept at the very heart of the inside, the city, and that too in public expense. In order to be led out of the city, the scapegoat must have already been within the city. 'The ceremony of the pharmakos is played out on the boundary line between the 'inside' and the 'outside', which it has as its function ceaselessly to trace and retrace'. Similarly, the pharmakos stands on the thin red line between sacred and cursed, '... beneficial insofar as he cures - and for that, venerated and cared for - harmful insofar as he incarnates the powers of evil - and for that, feared and treated with caution'. He is the healer who cures, and he is the criminal who is the incarnation of the powers of evil. The pharmakos is like a medicine, pharmakon, in case of a specific disease, but, like most medicines, he is, simultaneously, a poison, evil all the same. Pharmakos, Pharmakon: they escape both the sides by at once being and not being on a side. Both words carry within themselves more than one meaning, that is, conflicting meanings.

Pharmakos does not only mean scapegoat, It is a synonym for pharmakeus, a word often repeated by Plato, meaning 'wizard', 'magician', even 'poisoner'. In Plato's dialogues, Socrates is often depicted and termed as a pharmakeus. Socrates is considered as one who knows how to perform magic with words, and notably, not with written letters. His words act as a pharmakon (as a remedy, or allegedly as a poison as far as the Athenian authority were concerned) and change, cure the soul of the listener. In Phaedrus, he fiercely objects to the evil effects of writing, which, obviously, is what makes Derrida so interested in this book. Socrates compares writing to a pharmakon, a drug, a poison: writing repeats without knowing, creates abominable simulacra. Here Socrates deliberately overlooks the other meaning of the word: the cure. Socrates suggests a different pharmakon, a medicine: dialectics, the philosophical form of dialogue. This, he claims, can lead us to the truth of the eidos, that which is identical to itself, always the same as itself, invariable. Here Socrates again overlooks the 'other' reading of the word 'pharmakon': the poison. He acts as a magician (pharmakos) - Socrates himself speaks about a supernatural voice that talks through him - and his most famous medicine (pharmakon) is speech, dialectics and dialogue leading to ultimate knowledge and truth. But, ironically, Socrates also becomes Athens's most famous 'other' pharmakos, the scapegoat. He becomes a stranger, even an enemy who poisons the republic and its citizens. He is an abominable 'other'; not the absolute other, the barbarian, but the other (the outside) who is very near, like those outcasts, who is always-already on the inside. He is at once the 'cure' and the 'poison', and just like him, the Athenians chose to forget one of those meanings according to the need. And, at the end, Plato put Socrates in what he considered to be the vilest of all poisons: in writing, that survives to this day. Phaedrus and Socrates both stand as a metonym [very significantly meaning "beyond names"] for the whole contest between speech and letters, for the central (if such inappropriate word can be excused) theme of the Derridian project. The interplay between the words pharmakon-pharmakos-pharmakeus is another example of Derridian 'Trace'.
