Thanks to Christina Cogdell, here's a rundown on both.
In terms of philosophy:
Modernism retains a hierarchical theory in its approach. It's that of the purist and mainstream mindset that rejects or marginalizes other groups/cultures. Generally this group is white/elitist and celebrates the cerebral individuality- rational and functional. There's also a kind of universal truth behind modernism- modernists espouse the belief that their way is best/pure. It values newness and uniqueness and caters to an audience that is supposedly elite, sophisticated and serious.
This is Phillip Johnson's Glass House, a typical modernist example- pure, minimal, exposed, simplified.
The Lovell House by Richard Neutra, (Pacific Palisades) was one of the first examples of the International Style- note the horizontal orientation, rooftop garden, free facade, and pillar support foundation.
In terms of style: Modern architecture, and especially the International Style, emphasizes volume rather than mass, utilizes skeletal structures rather than heavy massed supports that form the exterior facade, promotes technology in its design- often at the expense of the client or social context. It rejects any ornamentation, partly in the attempt to create a "purist" structure and at times to exclude anything extraneous that is not cost effective. Modernism is a universal approach to architecture and the problem is that cultures function so differently from one to another that it often neglects the needs of its inhabitants- like it's a one-size-fits-all kind of structure. That said, there are many different styles of modern architecture that reflect different sociopolitical ideals, cultures, and theories, though the essence of modernism is aimed at improving social conditions while using new building technologies and materials.
So between the shift from modernism to postmodernism came the thought of "less is more" to "less is a bore" type of thing.
Postmodernism, in theory, seeks to break apart and deconstruct the purist and ideal mindset. Its style is really a hybrid pastiche approach that doesn't really reference any particular point in history. Its form doesn't bear a resemblence to its function. It's a melting pot of different styles that attempts to poke fun at the seriousness of modernism, create humor in its design and emphasize diversity. It acts as if it's opposed to hierarchy (although this too was practiced almost solely by white men). It also blurs the distinction from what was previously considered separate, celebrates complexity and contradiction, and addresses the social context in its design.
The Best building is probably the best representation of postmodern architecture I could find. It's literally a deconstructed box.
Team Disney Building, in Burbank is a good example of how it postmodernism pokes fun of different styles. It mocks the seriousness of the neo-classical style using the dwafts as the column and pediment.
Here's an example of postmodern design that mocks the Gothic Revival style. It's also modern in the sense that it's paired down to one piece- simplified in its structure.
Probably my favorite example of PM design. It completely mocks modernist ideals of "less is more"
and deconstructs down to nothingness...
Part of the emergence of postmodernism reflected what was happening with different social movements in the 60's, i.e. women's liberation, civil rights, drop-out culture of hippies and communes, anti-war movement, etc. Postmodernism is a bit of a sham in a way since it didn't actually do what it set out to do and is hypocritical in that the architects behind it were the same "type" of people postmodernists criticized to begin with- rich, white and elitist. It eventually failed mid '90's as it was not taken seriously, or all that functional or cost effective, or environmentally conscious.
