Definitely one of the most insightful books on depression I have read.
The current 'progressive' approach to depression, seems to be that it is an illness, just like any
illness that can be treated. Treat infectious disease with antibiotics; treat depression with medication or talking. But as the author write 'Dark nights of the soul are not ailments to be removed or
overcome, but are an acknowledgment that 'progress' through life is not necessarily linear, consciously directed or, at times, even possible' and 'Depression, with all its shapes and expressions, is just one of the necessary expressions of human existence.' Such an approach offers more hope to sufferers of depression. It's part of life and you can learn to manage it and learn from it.
