Pragmatism is the first refuge of a scoundrel

Good quote.  Hattip Samizdata:

In politics, many debates are polarised for a reason. There are usually profound differences in the ideological priors underlying viewpoints and the interpretation of evidence. We should therefore be suspicious of the arrogance of those who feel they don’t have to formulate arguments from first principles, and instead unilaterally announce themselves and their ideas as above debate.

How often do we hear, for example, “it’s time to take the ideology out of this debate”, or, worse, “I’m only interested in what works”? Often these are rhetorical devices which simply mean “shut up, and accept I’m right”. But in other instances, users of these banal phrases seem genuinely unaware that what they are saying has any sort of ideological assumptions underpinning it.
