I boka «Hidden wholeness» av Parker J. Palmer var det et avsnitt om dette jeg synes var fint:
Philosophers haggle about what to call this core of our humanity, but I am no stickler for precision. Thomas Merton called it true self. Buddhists call it original nature or big self. Quakers call it the inner teacher or the inner light. Hasidic Jews call it a spark of the divine. Humanists call it identity and integrity. In popular parlance, people often call it soul. And thus far in this book, I have called it by most of these names!
