118 페이지 - Most wretched men Are cradled into poetry by wrong, They learn in suffering what they teach in song.
113 페이지 - As buds give rise by growth to fresh buds, and these, if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever-branching and beautiful ramifications.
111 페이지 - It is a truly wonderful fact — the wonder of which we are apt to overlook from familiarity — that all animals and all plants throughout all time and space should be related to each other in groups subordinate to groups, in the manner which we everywhere behold...
95 페이지 - Altogether at least a score of pigeons might be chosen, which, if shown to an ornithologist, and he were told that they were wild birds, would certainly be ranked by him as well-defined species.
111 페이지 - On the view that each species has been independently created, I can see no explanation of this great fact in the classification of all organic beings; but, to the best of my judgment, it is explained through inheritance and the complex action of natural selection, entailing extinction and divergence of character, as we have seen illustrated in the diagram.

In the case of bodies more highly phosphorescent than paper, the spectres of many different objects which may have been laid on it in succession will, on warming, emerge in their proper order. This is equally true of our bodies and our minds. We are involved in the universal metamorphosis. Nothing leaves us wholly as it found us. Every man we meet, every book we read, every picture or landscape we see, every word or tone we hear, mingles with our being and...
97 페이지 - Latin ; if all historical documents previous to the fifteenth century had been lost ; if tradition even were silent as to the former existence of a Roman empire, a mere comparison of the six Romance dialects would enable us to say that at some time there must have been a language from which all these modern dialects derived their origin in common ; for without this supposition it would be impossible to account for the facts exhibited by these dialects.
98 페이지 - But a change from je suis to tii es is inexplicable by the light of French grammar. These forms could not have grown, so to speak, on French soil, but must have been handed down as relics from a former period — must have existed in some language antecedent to any of the Romance dialects.
