The Need for More (Part 2)
As we have seen, ‘having’ — the concept of ownership — is a fiction created by the ego to give itself solidity and permanency and make itself stand out, make itself special. Since you cannot find yourself through having, however, there is another more powerful drive underneath it that pertains to the structure of the ego: the need for more, which we could also call “wanting.” No ego can last for long without the need for more. Therefore, wanting keeps the ego alive much more than having. The ego wants to want more than it wants to have. And so the shallow satisfaction of having is always replaced by more wanting. This is the psychological need for more, that is to say, more things to identify with. It is an addictive need, not an authentic one.
