Anti Parsimonialism, Underrated or Overrated?

Iskno: The pursuit of parsimony is a bad idea. It becomes almost a religious quest. People think, if i can explain this phenomenon with one principle, i've produced a better explanation. And that's a disaster for the social sciences. I'm trying to advocate for what i'm calling a anti parsimonialism. You're a pluralist, and not like a utilitarian or no normativey. That means a that there are many human values. And if you take one, let's take liberty. Extremism in defence of liberty is no vice. Wrong. In defence of anya virtue becomes a vice. It becomes something that leads to horribln humanity and brutality
