Are Virtues Reliant on the Metaphysical Elements?

Do you have to believe in God to engage in those sort of spiritual exercises which could give you the emotional power to carry on in the face of absurdity? Well in my more recent book, The Spiritual Dimension, I addressed that question. The relationship between praxis, spiritual praxis and belief. Praxis being engagement in disciplines and traditions of action and practice. For example meditation which are aimed at the cultivating of these virtues we've been talking about such as hope.
