Reification is a specific form of alienation. It is actually confusion of model with reality. Or In other words it is error of treating something which is not concrete such as a thought or idea as a concrete thing. It is basically confusion of thought with reality. This term is used during natural language for instance and its use in logical language is misleading. Berger and Lockmann have defined it in subjective form. They were of the notion that reification is the tendency to see human yeild as if they were some other facts. It is basically providing a definite value to an abstract form.
