Weber meets Marxist under the Sociology tree

Proof of a causal relationship in reference to a logical scheme defines what counts as proof based upon what we are looking for. The proof including a description of the phenomena to be explained it helped out a lot if we keep as precise as possible the descriptions that arranged in observable and abstract categories. These discernible and conceptual groupings keeps is arranged through detailed statements of facts using generalized theoretical categories. This allows for comparison with other studies creating new and more complete generalizations. This is why Weber along with Marx were the parents of Sociology.
