The intersting question then is how do I find out if my model is adequate?

If every model is prone to bias through the perspective that it takes is it even possible to overcome the "perspective-ness" of models?

The answer of the postmodern thinkers would be: no. And they'd add that everything therefore is a power struggle where the winner takes it all.

It's not so easy to argue against this model, but anyone who is interested in doing so, I'd warmly recommend the book by James K.A. Smith: The Fall of Interpretation.

A hint where to look and what to look: a community that guards an agreed upon set of interpretation-rules...!
