Watch: a visit to the mysterious Georgia Guidestones

No one knows who erected the Georgia Guidestones in 1980. The Stonehenge-like monument is inscribed with 10 guidelines in eight languages:

Maintain humanity under 500,000,000 in perpetual balance with nature.
Guide reproduction wisely — improving fitness and diversity.
Unite humanity with a living new language.
Rule passion — faith — tradition — and all things with tempered reason.
Protect people and nations with fair laws and just courts.
Let all nations rule internally resolving external disputes in a world court.
Avoid petty laws and useless officials.
Balance personal rights with social duties.
Prize truth — beauty — love — seeking harmony with the infinite.
Be not a cancer on the earth — Leave room for nature — Leave room for nature.
