The New Age places strong emphasis on the idea that the individual and their own experiences are the primary source of authority on spiritual matters. It exhibits what Heelas termed "unmediated individualism", and reflects a world-view that is "radically democratic". It places an emphasis on the freedom and autonomy of the individual. This emphasis has led to ethical disagreements; some New Agers believe helping others is beneficial, although another view is that doing so encourages dependency and conflicts with a reliance on the self. Nevertheless, within the New Age, there are differences in the role accorded to voices of authority outside of the self. Hammer stated that "a belief in the existence of a core or true Self" is a "recurring theme" in New Age texts. The concept of "personal growth" is also greatly emphasised among New Agers, while Heelas noted that "for participants spirituality "is" life-itself".
