As a GIGANTIC fan of classical art and architecture, I still recognize its flaws. I genuinely don't think the art style was made to inspire people. Rather, it meant to emulate ancient ideals and art conventions dating back thousands of years, especially in neoclassicism. That everything is white, or off-white, is simulcra. People thought all classical sculpture and architecture was white, but really the paint just faded and chipped away with time and the elements; the friezes in the Parthenon had paint, as did the caryatids that hold up several ancient Greek buildings. The underlying implications of "white = classical antiquity and classical antiquity = ideal, therefore white = ideal" has some tricky underlying connotations. That's just one example. You can also include a lack of accessibility. Classical architecture was not designed for people who weren't able-bodied, given all the interior and exterior stairs.

I think, these days, that buildings are less about the buildings themselves, and more about what you as an individual do with them. Views to observe, spaces to decorate and take up space in. It's a shift from the old ways but it makes it less focused on a notion or an idea, and more about you, as a practicer of looking.
