PHL100Y1 Lecture Notes - Lecture 4: Reductio Ad Absurdum, Aporia, Thrasymachus
Document Summary
Justice consists in whatever you can away with. Justice is the advantage of the stronger (338c) Whatever you"re powerful to get, that"s justice. Socrates: not in physical strength but power: what counts then are the rulers who make the law. What is the point of a craft: argument strategy: redefining terms. Rightly interpreted, no craftsman ever errs , so a ruler qua ruler never makes errors (341a) This removes the factual premise: socrates: what is the point of the craft that you call ruling. Every craft aims at the good of something other than the craftsman (doctor, shepherd, etc. ) It is to his subjects and what advantageous and proper to them that (the ruler) looks : thrasymachus. Rejects the conclusion (i. e. make it a reduction: find a way around the argument) Takes the challenge of showing that injustice is not more profitable (345a)
