Thanks for this comment. Spengler referred to the Medieval Era as Spring because that was when what he saw as the key cultural forms first emerged -- such as linear perspective in painting, and soaring Gothic cathedrals - all of which he saw as manifesting a new cultural tendency to reach out to infinity which later seeped into maths and music. For Spengler, this sense and longing for infinitely wide and profound 3D space marked out the Western individual. I think what constitues the West is constantly changing. The historical base is Western Europe. If W. Europe and the US diverge in ideology over the next few decades (not necessarily a bad thing) then as a category the West will shrink back to the base. Possibly a bit larger if the EU stays intact or integrates further, as I hope it does.
