Some study of logicians - from Aristotle to the twentieth century. An introduction to simple formal logic, which can be applied in our daily lives to help with correct reasoning and hence clear thinking. This will assist us in exposing fallacies in the statements and reasoning of others - whether in casual, friendly conversation or the serious attempts of advertisers, politicians and public figures to influence our thought. Flawed and false arguments abound and in this course we will try to show ways to untangle them.
