Ah yes, my alma mat(t)er. But I prefer to (de-re)phrase it the saectum saectorum (from sanctum sanctorum), given my atheist bent, meaning the most common of the common. (In real terms this would be hydrogen.) Not to be confused with the rectum santorum.
Balder: I like saectum saectorum -- though given common connotations of 'common,' it has the danger of presenting 'matter' as 'all summed up,' fully known, nothing 'withdrawn' about it.
I don't like rectum santorum. That's just nasty!! :-0
me: Pannikar's use of saeculum is interesting referring to mystery. That's why I chose my de-re Latin phrase based on that usage, as intoning resonantly in that language creates a mysterious aura about it (as in Church). It is not just the common usage of common but that which is most common, like the most holy. Hydrogen is the most common and prevalent element in the universe, the very foundation of All but particularly stars. It's the fuel of cosmic combustion and yet the most mysterious phenomenon of All.
On a practical level, this is why hydrogen fuel-cell tech is on the forefront of clean, efficient energy. And no surprise that Rifkin plans to store energy as hydrogen once generated from his smart buildings. Hydrogen, the saectum saectorum, is the key to our sustainable future. It is quite literally hot stuff.
