Who is the philosopher of American Progressivism?

In describing some of the history of American Progressivism, Dinesh D'Souza asks a very provocative question:

Think about this: we know the name of the philosopher of capitalism, Adam Smith. We also know the name of the philosopher of Marxism, Karl Marx. So, quick, what is the name of the philosopher of fascism? Yes, exactly. You don’t know. Virtually no one knows. My point is that this is not because there were no foundational thinkers behind fascism – there were several – but rather that the left had to get rid of them in order to avoid confronting their unavoidable socialist and leftist orientation. This is the big lie in full operation.

Now, what about Progressivism? Who is the foundational thinker behind that? Like Italian Fascism, American Progressivism has several. They are:

1) Henry George

2) Edward Bellamy

3) Herbert Croly

4) Woodrow Wilson (Prior to 1912)

Just as those behind fascism have been erased out of the history books, so too have these men - with the exception of Woodrow Wilson, but only because he was a president. Nobody hears the name of Wilson and considers his "philosophical" writings, despite just how impactful they really were when they started to be written in the late 1880s. If Wilson never would have been president, he would've been erased too.

Because people do not know the names of George, Bellamy, Croly, and Wilson, that is the big lie in action.
