I mean also to include such a cultivation of the intellect, as shall enable it to discover those permanent and mighty laws which pervade all parts of the created universe, whether material or spiritual. This is necessary, because, if we act in obedience to these laws, all the resistless forces of Nature become our auxiliaries and cheer us on to certain prosperity and triumph ; but if we act in contravention or defiance of these laws, then Nature resists,...
Page 173 - A struggle for existence inevitably follows from the high rate at which all organic beings tend to increase. Every being, which during its natural lifetime produces several eggs or seeds, must suffer destruction during some period of its life, and during some season or occasional year, otherwise, on the principle of geometrical increase, its numbers would quickly become so inordinately great that no country could support the product. Hence, as more individuals are produced than can possibly...

Page 87 - I hardly need to say, that by the word Education, I mean much more than an ability to read, write, and keep common accounts. I comprehend, under this noble word, such a training of the body as shall build it up with robustness and vigor, — at once protecting it from disease, and enabling it to act, formatively, upon the crude substances of nature, — to turn a wilderness into cultivated fields, forests into ships, or quarries and clay-pits into villages and cities.
