Agricultural practice served Darwin as the material basis for the elaboration of his theory of Evolution, which explained the natural causation of the adaptation we see in the structure of the organic world. That was a great advance in the knowledge of living nature.

Scientific knowledge is in perpetual evolution; it finds itself changed from one day to the next.

Religion and science are the two conjugated faces or phases of one and the same complete act of knowledge - the only one which can embrace the past and future of evolution and so contemplate, measure and fulfil them.

Men are at every stage of evolution, from the most barbarous to the most developed; men are found of lofty intelligence, but also of the most unevolved mentality; in one place there is a highly developed and complex civilisation, in another a crude and simple polity.
