Thor Heyerdahl was a Norwegian explorer and ethnographer who is best known for his Kon-Tiki expedition, in which he sailed a balsa wood raft from South America to Polynesia to prove that it was possible for ancient people to have made the same journey. Heyerdahl was also a vocal critic of racism, and he coined the term "temporal racism" to describe the tendency to view people from different times as being inferior to those from the present.
In his book "The Kon-Tiki Expedition", Heyerdahl wrote:
"The most harmful of all these phantoms is the acrochronism, the belief that our own time is the highest and that all earlier times were inferior. We believe firmly that our time is the time of the greatest progress, the greatest civilization, the greatest humanity, and that far behind us lie the times of savagery and barbarity. We call our time the Age of Reason and behind us we imagine the times of faith and superstition."
Heyerdahl argued that temporal racism is a form of prejudice that can lead to discrimination and oppression. He believed that it is important to challenge temporal racism and to remember that all people are equal, regardless of their time period.
