As a scientist who used evolutionary change through time throughout my career to determine geologic sequences of sedimentary rocks and to identify determine past environmental conditions, mostly in aid of petroleum exploration, I regard the encyclical "Humani generis" at the Vatican website as complete nonsense.

In our supposedly enlightened age it is superstition that leads to statements such as "some imprudently and indiscreetly hold that evolution, which has not been fully proved even in the domain of natural sciences..." "and audaciously support the monastic and pantheistic opinion that the world is in continual evolution." "Communists gladly subscribe to this opinion..." "Dialectical materialism."

The Catholic Church is the great fount of superstition in our world; it is not alone, but the brain-washing tactics of this giant structure do the most damage.
