You might like Kenneth Burke's Permanence and Change. Burke was not a philosopher per say; he was more of a philosophical literary theorist.

Alain Badiou's work on "the event" might also interest you. The gist of it is that "the event" is the name for a radical change in a situation such that the situation can no longer go back to normal. It happens in four domains: science, love, art, politics. Just to give two examples, a love-event can just be when two people fall in love and they cannot accept their previous conditions anymore. Think Romeo and Juliet, for example (note that it doesn't have to be only two people). In politics, the idea of democracy seems to persist through the ages, even when it is being suppressed. There is something about the idea of society run by the people that has an enduring calling on people across time and cultures.

Badiou lays this out in his major work, Being and Event. It is a doozy of a book, but you can find a pretty good summary of it in Zizek's The Ticklish Subject.
