Iván Szelényi’s course on the Foundations of Modern Social Theory is a fascinating trip through some key thinkers, from political philosophers to economists, psychologists and more broadly based social scientists. If anything, perhaps, it shows how blurred the lines are between the disciplines; linking Marx, Nietzsche, Freud and Weber to me at least was not clear: Marx was either a political scientist or an economist; Nietzsche was an existentialist philosopher; Freud was a psychologist; and Weber a sociologist. Where they coalesce, Szelényi suggests, is that they are all critical theorists. They are concerned with consciousness, with what is in the mind. Giving voice to their common purpose, he said they are suggesting that ‘[w]hat is in your mind is not necessarily what you think it is. Let’s subject your consciousness to critical scrutiny.’ His heavily accented presentation is both compelling and dramatic, and the course is to be recommended, as is the Open Yale program in general. A fabulous educational resource.
