Page 4 - The question of questions for mankind the problem which underlies all others, and is more deeply interesting than any other is the ascertainment of the place which Man occupies in nature and of his relations to the universe of things.
Page 11 - Thus, whatever system of organs be studied, the comparison of their modifications in the ape series leads to one and the same result that the structural differences which separate Man from the Gorilla and the Chimpanzee are not so great as those which separate the Gorilla from the lower apes.
Page 4 - Man occupies in nature and of his relations to the universe of things. Whence our race has come; what are the limits of our power over nature, and of nature's power over us; to what goal we are tending; are the problems which present themselves anew and with undiminished interest to every man born into the world.
Page 86 - ... part; and he maintained that, since nature takes no sudden leaps, even organs which are superfluous in any given species, if they have played an important part in other species of the same family, are retained as rudiments, which testify to the permanence of the general plan of creation. It was his conviction that, owing to the conditions of life, the same forms had not been perpetuated since the origin of all things, although it was not his belief that existing species are becoming modified....

Page 94 - He also demonstrated the presence of neuroglia in the brain and spinal cord, and discovered crystalline haematoidine, and the true structure of the umbilical cord. In pathology, strictly so called, his two great achievements the detection of the cellular activity which lies at the bottom of all morbid as well as normal physiological processes, and the classification of the important group of new growths on a natural histological basis have each of them not only made an epoch in medicine,...
Page 12 - In fact it is very difficult to show why man should not be classed with the large apes in the same zoological family. We all know a man from an ape; but it is quite another thing to find the differences which are absolute and not of degree only.
Page 157 - The primal conception of monism is, first, "that there lives one spirit in all things, and that the whole cognizable world is constituted and has been developed in accordance with one common fundamental law.
Page 91 - Perhaps all animals are alike, and nothing but hollow globes at their earliest developmental beginning. The farther back we trace their development, the more resemblance we find in the most different creatures. And this leads to the question whether at the beginning of their development all animals are essentially alike, and referable to one common ancestral form. Considering that the germ (which at a certain stage appears in the shape of a hollow globe or bag) is the undeveloped animal itself,...
