The "Left - Right" philosophical divide is nothing new. Both sides see a different reality from the other. This can be traced to Plato vs. Aristotle's view of reality.
Plato (Theory of Forms):
The abstract is primary and more real. Eternal, perfect Forms (e.g., Beauty Itself, Justice Itself, Equality itself) exist in a transcendent realm. Reality flows from abstract ideal to concrete world; knowledge is of the Forms via reason.
Aristotle (Primary Substances & Hylomorphism):
The concrete is primary and foundational. Individual, tangible particulars (this man, this horse) are the basic realities (primary substances). Abstracts (universals, forms, essences, ideals) are secondary—they exist only in or derived from concretes via abstraction from particulars. Without concrete particulars, abstractions could not exist. Knowledge starts from sense perception of the tangible world.
In short: Plato (current day Left) Places the Abstract first (Platonic idealism: ideals shape reality).
Aristotle (current day Right) Prioritize Concrete first (realism: reality grounds abstractions).
The implications of this difference are profound.
