Johnstone's theory of informal logic

Johnstone's theory of informal logic focuses on how people reason and communicate in everyday situations, outside strict formal logic. It emphasizes understanding arguments as they naturally occur, highlighting the importance of clarity, context, and reasoning processes like evaluating evidence and identifying assumptions. The approach encourages critical thinking about arguments encountered in daily life, teaching us to recognize weak reasoning, fallacies, and persuasive techniques. Essentially, Johnstone’s theory promotes interpreting and assessing arguments in real-world conversations, making reasoning more accessible and meaningful beyond formal structures.
