Many people are convinced that modern science has made religious belief impossible. But this way of thinking may be based on an oversimplified idea of what religious belief is. This course will explore the idea that spiritual truth is a different kind of truth than factual truth — a truth not about the physical universe but about our own human nature. Recent biological and psychological studies of the human brain and human experience suggest that our sense of reality is not as simple and straightforward as it seems. The ultimate truth about our own nature may not be something we can understand–it may instead be something we can realize only through practice. This insight suggests that religions are systems for enabling people to realize spiritual truth in practice.
