According to Stephen Pinker, "The Blank Slate", cultural traditions advance the level of education and knowledge when they interact and are not isolated geographically.

Cultural heritage is only as important as it defines your personal journey but to stay in
that and not recognize others' cultural heritages is destructive to personal growth.

The best explosions in music have been when musical cultures collide such as in jazz,
most folk music (unlike the popular conception that it is isolated), classical music and other
creative forms including rock, r and b etc.

When the palette is larger, the pictures are often richer.
