'Words, words, words' I love words and I love linguistics. I know next to nothing of the whole subject but I just enjoy 'word talk'. Where they come from, how and when they came. What they mean or used to, how they die their slow death in dusty pages. Or revive, and jump at you in a guise they never before wore in your mind's eye.
The latest jewel of my wonderment is 'idiot'. No risk to forget this one though, no need to mobilize the vacuum-cleaner to allow its meaning to enter the brain. And yet I only recently realized that 'idiot' and 'idea' might come from the same place, don't they look alike? And which comes first is self-evident; the idiot speaks, ideas follow in the wake of his words and trailing after them, who? but the philosopher, thinking; thinking thoughts, in other words pondering what idiots say, being smart about stupidity. Throughout the day they contemplate and consider and far into the night, day in and day out, confusing at last dusk and dawn they start making up propositions... for politicians to further elaborate on the workings of morons!
In fact this is what 'idiot' says (and how to say it to speak Idiotish), but not 'idea' although they do come from the same place, the Pontic Caspian steppe, where our indo-european languages were spoken around 3500 bce; same people, different roots (thefreedictionary.com).
But there are so many of these roots and it was a long time ago and as roots grow they get entangled and bury themselves further and further away from the light and it is ever more difficult to take them apart, to make them out without special tools to dig the truth from so deep down... which is why politicians can make us believe they got ideas and philosophers often speak like idiots.

La France, ai-je entendu dire, culpabiliserait d'avoir coupé la tête de son roi aux temps héroïques de la révolution. Et j'ai même entendu certains avancer que pour expier cette ignominie la meilleure preuve de repentance, devant l'histoire et la communauté internationale, serait de guillotiner un président. Ou deux, ou trois; depuis 1793 ça en fait des intérêts composés! Et les économies qu'on ferait!


S'il n'est plus à prouver que nos aïeux n'étaient pas aussi uniformément Gaulois que le voulait certaine habitude de pensée, il serait temps quand même que l'on reconnaisse que les ancêtres de nos actuels maîtres étaient Francs, venus d'outre-Rhin, salauds d'immigrants. Francs, complètement. Ce que l'on observe sans peine chez leurs descendants qui se font appeler "Nos élus" par les électeurs, "vos représentants" par les journalistes et "leurs" parlementaires par les étrangers. Nos, Vos, Leurs par tout le monde en somme!"
