Each domain has its own organizing distinction. The political is not derived from the others — click each to compare.
The Political
Friend / Enemy
The political distinction is not about who is morally good or economically useful. The enemy is simply the other — the stranger — who poses an existential threat to one's own way of being. The political is the highest intensity of association and dissociation.
Aesthetics
Beautiful / Ugly
Aesthetic judgments concern form, harmony, and taste. They are not political. A political enemy may produce beautiful art; aesthetic disagreement alone never rises to political enmity.
Economics
Profitable / Unprofitable
Economic relationships are about exchange, profit, and interest. Liberalism tries to reduce the political to economics — to replace enemies with trade partners. Schmitt argues this always fails: economic conflict can become political, and commerce never eliminates enmity.
Morality
Good / Evil
Moral categories are not political categories. When a political conflict is framed as good vs. evil, morality has been borrowed by politics to add intensity. The enemy is not evil — he is the enemy. Moralizing warfare is, for Schmitt, the most dangerous form of politics.
