No naturalist has devoted more painstaking attention to the structure of the barnacles than Mr. Darwin.

The powers, aspirations, and mission of man are such as to raise the study of his origin and nature, inevitably and by the very necessity of the case, from the mere physiological to the psychological stage of scientific operations.

Mr. Darwin refers to the multitude of the individual of every species, which, from one cause or another, perish either before, or soon after attaining maturity.

Rapid innovation is the cure for the ills we face, but because innovation is difficult and susceptible to failure, we might need to rethink the way we approach innovation and how we drive it through our companies.

Mr. Darwin contributes some striking and ingenious instances of the way in which the principle partially affects the chain, or rather network of life, even to the total obliteration of certain meshes.

Every step in the progress of this study has tended to obliterate the technical barriers by which logicians have sought to separate the inquiries relating to the several parts of man's nature.

Manifold subsequent experience has led to a truer appreciation and a more moderate estimate of the importance of the dependence of one living being upon another.
