“Si materialistes qui fussent les premiers evolutionistes il ne leur venaient pas l’idee que leurs intelligence de savants eut rein a faire en Elle-meme, avec l’evolution” Pierre Teilhard de Chardin
Teilhard de Chardin is here making a point about materialists in the field of evolution, such as Darwin and the moden day Richard Dawkins. What he means is that materialists imagine themselves as observers, separate from what they comment upon. Yet they, and their brains are a result of and part of evolution.
Another human trait is to feel superior to what you observe. The act of viewing something as separate leads to a sense of boundary; from which follows..
Materialism, arrogant. Illogical.
