The regulation was not put in place to foster violence; somewhat, it aimed to limit it. The Lex Taleonis envisioned a authorized world the place all the pieces might be described by linear equations: each crime would create an output proportional to its enter. And for the reason that punishment for an offense was proportional to the crime, it averted extreme retribution and explosions of violence that left all the pieces of their wake destroyed.
Past the world of retribution, linearity performs an necessary position in our fascinated with the world: in linear methods, all the pieces is known. There isn’t a chaos, no difficult maths. All scientists must do all day was remedy these sorts of equations:
For each motion, there’s an equal and reverse response.
— Newton’s Third Legislation of Movement
Sadly, the truth we inhabit is much from this linear utopia. Historical past is ripe with examples of the world responding to small issues in extremely disproportional methods: the Defenestration of Prague sparking the Thirty…
