“Mammals were added next, until Nature became what she now is, by the addition of Man. …the generalisation, as laid down by the Woodwardian Professor, still holds good in all essential particulars.”

Context: The doctrine of progression... was thus given twelve years ago by Professor Sedgwick, in the preface to his Discourse on the Studies of the University of Cambridge. 'There are traces,' he says, 'among the old deposits of the earth of an organic progression among the successive forms of life. They are to be seen in the absence of mammalia in the older, and their very rare appearance in the newer secondary groups; in the diffusion of warm blooded quadrupeds (frequently of unknown genera) in the older tertiary system, and in their great abundance (and frequently of known genera) in the upper portions of the same series; and lastly, in the recent appearance of Man on the surface of the earth.' 'This historical development,' continues the same author, 'of the forms and functions of organic life during successive epochs, seems to mark a gradual evolution of creative power, manifested by a gradual ascent towards a higher type of being.' 'But the elevation of the fauna of successive periods was not made by transmutation, but by creative additions; and it is by watching these additions that we get some insight into Nature's true historical progress, and learn that there was a time when Cephalopoda were the highest types of animal life, the primates of this world; that Fishes next took the lead, then Reptiles; and that during the secondary period they were anatomically raised far above any forms of the reptile class now living in the world. Mammals were added next, until Nature became what she now is, by the addition of Man.... the generalisation, as laid down by the Woodwardian Professor, still holds good in all essential particulars.

“Because the purity of the eye of the soul is obscured and weighed down by the corrupt body, all the powers of this rational soul born in man are laid hold of by the mass of the body and cannot act and so in a way are asleep.”

Robert Grosseteste (1175–1253) English bishop and philosopher

Accordingly, when in the process of time the senses act through many interactions of sense with sensible things, the reasoning is awakened mixed with these very sensible things and is borne along in the senses to the sensible things as in a ship. But the functioning reason begins to divide and separately consider what in sense were confused. ...But the reasoning does not know this to be actually universal except after it has made this abstraction from many singulars, and has reached one and the same universal by its judgement taken from many singulars.
