Yeah it's not an article. It's just a snippet on Wikipedia about the Five Moral Foundations and then talks about how liberals over value "Fairness" and "Care" and undervalue (compared to conservatives) "Loyalty", "Authority", and "Sanctity". And then libertarians are their own offshoot and they value a hypothetical 6th category called "Liberty", which matters to them way more than anything else.
You're supposed to buy the book to get an in-depth breakdown with concrete examples, etc. I just thought this snippet was kind of an interesting look at why liberals and conservatives think differently. It's just one academic way of trying to quantify the differences in values between the two groups. Does that make sense?
