 When I read about the Prophet's motive, immediately my mind came the Gordon Gagel phrase, greedy is good or lunch is for whims. But I sense that you give a different flavor to the Prophet's motive. And indeed, Einrand in Atlas Triumph gives a totally different aspect of the Prophet's motive. Could you brief us on what's the position of the Prophet's motive into the objective in the philosophical system? Well, the idea is that Prophet is good, Prophet is moral because Prophet represents, it's a market signal for the value you create. So when Apple builds an iPhone and it sells it for $400, it cost Apple a lot less than $400 to put it together. But that combination, I'm willing to pay $400 for. Why? Because that iPhone is going to be much more valuable to my life than $400.
