Discard all stereotypes and choose your fundamental logics from the mountain of history to create your own system for interpreting the world.
What's important is not the completeness of the logic, but how much the logic corresponds with common sense in the world. Rather than the standard of what should be (당위의 잣대), if we look from the standard of understanding (이해의 잣대) why it is so, we don't need to justify ourselves as victims (피해자 코스프레로 정당화). Because human perception has its limits, if my logic feels perfect, it's a delusion.
Logic - Wikipedia
Logic is the study of correct reasoning or good arguments. It is often defined in a more narrow sense as the science of deductively valid inferences or of logical truths. In this sense, it is equivalent to formal logic and constitutes a formal science investigating how conclusions follow from premises in a topic-neutral way or which propositions are true only in virtue of the logical vocabulary they contain.
