For those of you completely uninterested in philosophy, I can’t blame you, at least based on the current and elitist state of the discipline. Philosophy, however, hasn’t always been viewed in the terms that it is today; for Plato, philosophy was, after all, an erotic expression of love for the true order of things, a definition that formed the basis for a good chunk of Christian theology both then and now. So if you’re interested in learning how to do philosophy at a deeper and more constructive level, these introductory lectures by Roderick on the history of ethics are a great way to learn.

Here Roderick talks about the need for absolutes without being willing to define them.
