I don't think the effectiveness will go away - not in a society that wants to narrowly define what the meaning of 'is' is.

Our world swings between two distinctly different ways of thinking - Semitic Thought is story based. Hellenistic Thought is definition (think, list) based. Semitic thought is a narrative where principles and precepts are communicated as part of an incredible picture painted with words. Hellenistic thought is a detail driven exploration of the beauty found in exactness. Interestingly enough, modern Islamic cultures most closely represent Semitic Thought these days while the rest of the world thinks like Hellenists.

The best blogs - and teachers - I know effectively combine the story with the list. Powerful principles illustrated with compelling stories.

God Bless,
