Some wisdom from Seth Godin:
An organization uses structure and resources and power to make things happen. Organizations hire people, issue policies, buy things, erect buildings, earn market share and get things done. Your company is probably an organization.
A movement has an emotional heart. A movement might use an organization, but it can replace systems and people if they disappear. Movements are more likely to cause widespread change, and they require leaders, not managers. The internet, it turns out, is a movement, and every time someone tries to own it, they fail.
A philosophy can survive things that might wipe out a movement and that would decimate an organization. A philosophy can skip a generation or two. It is often interpreted, and is more likely to break into autonomous groups, to morph and split and then reunite. Industrialism was a philosophy.
The trouble kicks in when you think you have one and you actually have the other.
