Relation
Hegel (synonym for "Verhältnis")
Relation is a bond, a connection. In Kant, one of the four groups of categories (substance/accident, causality, reciprocal action). Important throughout in Hegel: relations are not external between ready-made terms; rather, the terms exist only through their relation. Example: teacher/student are relational concepts - neither exists without the other. Highest form: self-knowing relation (reciprocal action, concept).
