Arguing about facts gets us nowhere. Instead, we argue about the interpretation of facts and the trustworthiness of their representation. Both aspects are matters of preference. They boil down to your basic assumptions about human society, human thought and the human universe. They are ideological, a word that immediately brings to mind blind faith, false consciousness and lies.
Ideology is a bad word for good reasons.
Ideological thinking is inferior thinking. It is narrow-minded and blind to anything that veers off the ideological path. We rarely choose ideologies for their logical and factual merits. Even when we do, the choice itself limits us to continuing that train of thought. We are bound up in something greater than the intellectual debate, being cast up and pushed forward by the waves of history.
