A philosopher called Ortega y Gasset said one time “When someone believes in an idea, the idea lives”. When I was thinking about the idea “share”, it reminds me to this phrase. If this phrase is true, to share means to intensify the existence of an idea (or creation), to make it more real, because some more people are believing or thinking in the same idea.
The bowl of the ideas are the minds of the people. To share is to spread the idea into new minds.
