To think and learn without realising it, because you are having fun! Students will understand the Time-Lag Argument and the debate between Direct and Indirect Realism and the implications this has on our access to external reality as a foundation for empirical knowledge and Epistemology. We also briefly look at Presentism and Eternalism as modern Theories of Time and finish by looking at the Evolution of Mind and how we access external reality in relation to the Philosophy of Mind and Perception.

I have a PhD in Philosophy and have taught this class many times - it's one of my favourites and all my students have really enjoyed it too.

The Stanford Encyclopedia of Philosophy is a well respected reviewed source of great introduction into a Philosophical Topic. There also many follow on references at the bottom of each article. Wikipedia is also a good starting point, but is obviously less reliable as it is not peer reviewed.
