Interpreting Informal Logic

Informal logic is a logic of argument or philosophy (theory) of argument. It resulted from the response of university logic course to the need of actual life. There are different understandings about the object and nature of informal logic. There are also oppositions to informal logic. Though informal logic is still out of the vision of the mainstream philosophy, it is worth attaching importance to in that it examines a series of argument problems from unorthodox logic vision.
