Most of it, but don’t discount the Latin impact (not from Spain) the Norman-French (which took us out of something of an extension of Scandinavia and brought us firmly into the embryonic Western culture) and later England’s part in the Renaissance meld with the scientific revolution. Only a culture strongly influenced by Classical civilisation could have achieved the feat of separating Plato and Aristotle from science. England has existed as a somewhat unique blend of the north and south.

The Celts have barely had a look in, it is practically impossible to trace any real Celtic influence on the English mind, which is quite remarkable really when you think the Celts probably account for at least a good half, if not most, of English population genetics.
