Boo-Hurrah for the Enlightenment

One should always try and rescue words from the work they are made to do in the current rhetorical marketplace, to set aright what stupidity and polemic have turned upside down or reduced to convenient and misleading abbreviation. . One presently rather overworked term is ‘Enlightenment’.

The Virtual Stoa has some questions about the term. He writes:

I think it's worth having answers to questions like these -- otherwise you just end up in a position where you can cheerlead for "the Enlightenment" (the rule of law! democracy! science!) or just slag it off for the bad things you vaguely associate with it somewhere along the way (racism! sexism! Revolutionary Terror!) without letting anything as complicated as history or evidence get in the way of your arguments. And that'd be a shame.

The conditional tense is presumably ironic. But if Chris or anyone thinks that the polemicists who have reduced 'Enlightenment' to a cheap catchphrase just need a few hours in the library, or that the said phrasemongers would welcome enlightenment as to the meaning of Enlightenment, that they actually care about this as a historical or philosophical question, then we are dealing with something akin to a category error.
