Abstract
Hegel (methodological qualification)
For Hegel, "abstract" means: one-sided, isolated, poor in determinations. The abstract has abstracted from mediation, treating a moment as though it stood on its own. Examples: pure being (the most abstract category), formal identity (A=A), the isolated consideration of a single thing. "Abstract" functions as critique: something has been grasped too one-sidedly. Understanding [Verstand] works abstractly (it separates, it fixes). Reason [Vernunft] wants to become concrete (mediated, living). The movement of the Logic runs from abstract to concrete.
Origin
From Latin abstrahere (to draw away, to take away). Traditionally, abstraction is what forms general concepts. Hegel reverses this: abstract = poor, one-sided (not: general). The general can itself be concrete — as a developed totality.
