Humanity has mostly been comprised of philistines for much of its history.

Primal interests.
Primal needs.
Survival-focused coupled with a rational mind.

Now that we are less concerned, day to day, about survival, some of humanity is less primal and driven by survival instincts.

This group tends to look forward. It projects the potential of humanity and desires to get there quickly.

But the philistines hold everyone back.

This situation has been improving all along, but slowly.
