Critical Realism

This article takes a look at Alistar McGrath's endorsement of crtical realism. This is a very important topic. Here is a little tibdit from it- feel free to read the entire article at the bottom.

Naïve realism: Reality impacts directly upon the human mind, without any reflection on the part of the human knower. The resulting knowledge is directly determined by an objective reality within the world.
Critical realism: Reality is apprehended by the human mind which attempts to express and accommodate that reality as best it can with the tools at its disposal – such as mathematical formulae or mental models.
Postmodern antirealism: The human mind freely constructs its ideas without any reference to an alleged external world.
