Indeed, magic and spirituality play an important role not only in the practice of many forms of Paganism, but also in the shaping of Pagan ethics. Magic is grounded in a recognition that self-interest and care for one's own family and tribe are acceptable principles of action; in this sense, Pagan spirituality functions quite well within a democratic capitalist economy, where self-interest is a foundational social principle. However, some magical communities impose restraints on the morality of self-interest, whether in terms of the Rede's "harm none," in terms of classical or mythological concepts of virtue, or in terms of balancing the competing interests of personal self-interest with the mandate for environmental responsibility and sustainable living.
Ultimately, no universally observed ethical principles define the Pagan movement as a whole, although mythologically-derived notions of virtue and honor, the wiccan Rede, the acceptance of magic as a tool for exercising spiritual power, and a balanced sense of the importance of caring for the environment are widely held values.
