Humani generis

Humani generis is an encyclical published by Pope Pius XII on August 12, 1950, on false opinions against the foundations of Catholic doctrine. It is a document that consolidates and extends the sentences that Saint Pius X accuses in the encyclical Pascendi Dominici gregis.

In it, the compatibility between Catholic religious beliefs and scientific research is reaffirmed, but, at the same time, it reaffirms the immutability of the fundamental postulates of religion.

No truth that the human mind has been able to discover through sincere research can be in contradiction with the already known truth because God Suma Truth has created and tolerated human intelligence not to oppose every day new truths to the firmly acquired truths, but to have once the mistakes that arise, that intelligence adds truths in the same order and with the same organicity that we see in the very nature of the things where the truth is born.
