Here’s an interesting site where the author breaks it down into simplistic steps. There are some that I wouldn’t agree with on what is conservativism. It might make sense in today’s climate (and that’s what the author is saying), but as a philosopher, conservativism is something different than how it’s being used today.
On the flip side, he also has a list of what is progressivism. Again, not everything on the list I agree with, but it’s a very nice summary on both counts to suggest what the differences are.
