    "Are you people daft? The material _absorbs_ light! That doesn't mean it is invisible! It means it is black!"

    That's not true. The point it is not that it absorbs light; it is that it doesn't *reflect* light. While a method not to reflect light is being black, it is not the only one: a transparent thing doesn't reflect light either. And since this material's refractive index is compared to that of glass or even thin air, you can go figure.

    Your must remember that air is, for the most part just "dirty" vacuum: there's aplenty of empty space among air molecules, and they all are just "wandering at will". Of course, there's a chance that by mere casuality all air molecules wander just to a corner of a room, so all the rest of the volume is empty and you suffocated. Of course too, when you consider the *hughe* number or molecules there are in a room (just remember Avogadro's number), you can expect having to wait quite a lot universe lifes to see such an event.

    "Once again, you pose a false dichotomy."

    I think you are playing words. Of course "revelation" dictionary-sense, can be reasonable: I can revelate to you that I won the lotto. You knowing I'm trustworthy, and looking at my new luxury car will reasonably believe it.

    But this is not the theologal meaning for "revelation". Revelation is what God told us because a) He is in mood to tell us and b) we have no natural means to know it.

    Believing a revelated truth requires no reasonement but *faith*. Even if God came down from heaven to tell me, a poor ignorant, that apples do fall at a speed that increases 9.8 metres per second each second at ground level, that wouldn't be a revelation (theological sense), because we can see and understand that ourselves. It is when God comes to Earth to tell that His Almightyness is somehow One and Three at the same time, or that we will live beyond death that it's a revelation since there's neither no reasonement nor natural means to know that for a fact, except God Himself coming here to tell us.

    "Revelation can sometimes be varified independently, but it is not a pre-requisite for it."

    Revelation can *never* be independently verified. The nearest thing to it is prophecy, but -again theologically, a prophecy and a revelation are different beasts.

    Well, well... To Caesar that from Caesar. On one hand you mean to imply that it was some "Catholic Church" oscurantism that that went after muslims in Spain. While that (as always) it an explanation to the masses (and probably make the fight), it was (as always is) a fight for power, for land and sea power those days. Is not by chance that the christian king of the day was "the Catholic Fernando" which is pondered as a mirror for statemen to learn their bussiness by no less than Machiavelo.

    On the other hand, by the end of the fifteenth century (Granada was taken by the catholic kings on february the 2nd, 1492, the same year Colon -sponsored by those same kings, arrived the New Continent) all the south of Spain (till the time it went conquered by spanish christian kings) was known as "Taifas Kingdoms", short of little warlord reigns that fought against each other (even within kingdoms: Cordoba caliphate was destroyed by a civil war) no less than against the pressure from the christian principals. So, while the merit (and the history fact) came on the side of the Spanish christian kings it was muslims themselves the real makers of their own defeat (under this insight it takes a new sense the words that the Granada's king's mother told him when flying from the taken city: "cry like a woman what you weren't able to defend like a man").

From more or less X century to the end of IWW the "big" Europe (including Asia Minor, North of Africa and East Europe to Caucasus) is the time when societies come from warlordships to modern states at a highest price in blood.

Today is quite fair to say that current standards are low because both their true level and where we come from (the standards that people wanted for themselves by the years following the end of IIWW) cast deep shadows of shame on us.
