Quote:So all those outside places influenced western civilisation.
They were western civilisation. The "west" didn't magically emerge from a bunch of clever european hunter gatherers a few centuries ago at the start of the industrial revolution. It has been developing very slowly since farming started in earnest in the middle east about 10000 years ago.
Quote:Find one author who says the West was outside Europe at that time.
Same answer to the last time you asked.
Quote:Again, how can Islam destroy what was already destroyed?
Rape. Pillage. Slaughter. Oppression. Basically, what Muhammad did to the previously multicultural society of Mecca and surrounds, expanded over nearly all of western civilisation. The term I used was "locked in". Civilisation has a habit of re-emerging from the ashes. It is very difficult to destroy. The destruction of the Roman Empire was not necessarily the same thing as the destruction of western civilisation. Same with all the previous civilisations in Egypt and further east that collapsed and sprang up again. They did not re-invent the wheel every single time, and just happen to do it bigger and better. People remember and do it all again on a grander scale. Unless something like Islam comes along and doesn't let it.
That's why the European fringe was able to build on what they inherited from Rome and all the previous civilisations. It inevitably inherited much of the knowledge, culture etc during Roman occupation, but escaped the degradation of Islam. Many Americans today still throw the word "republic" around with more reverence than the word democracy. This is not because the Muslims failed to destroy every copy of The Odyssey and allowed the Europeans to get hold of a copy. It's because their ancestors were ruled by Rome and spent centuries marvelling at the infrastructure left behind by them, which piqued their interest in how the Romans managed to create such a grand empire, and their ability to relate to the efforts of the early Romans (and Greeks etc) to avoid being ruled by tyrants.
