Pierre-Paul Grassé

“Natural order was not invented by the human mind or set up by certain perceptive powers... The existence of order presupposes the existence of organizing intelligence. Such intelligence can be none other than God's.”

“The study of contemporary species does not establish the existence of evolution; it provides facts which support it, but which do not fully demonstrate its existence. This is understandable, since at present we cannot show the series of successive stages which make up evolution, but only a fleeting picture of evolution.”

“The mutation of bacteria and viruses are merely hereditary fluctuations around a median position; a swing to the right, a swing to the left, but no final evolutionary effect.”

“The philosopher considering the Universe in its entirety is led to admit that there is only one necessary, absolute being, God. All other beings are contingent; this is why Pascal said of himself: "I feel that I might not have been... therefore I am not a necessary being" (Pensées, No. 597). The proposition applies equally to every living thing.”
