Strona 244 - The hell to be endured hereafter, of which theology tells, is no worse than the hell we make for ourselves in this world by habitually fashioning our characters in the wrong way. Could the young but realize how soon they will become mere walking bundles of habits, they would give more heed to their conduct while in the plastic state. We are spinning our own fates, good or evil, and never to be undone.
Strona 244 - Habit is thus the enormous fly-wheel of society, its most precious conservative agent. It alone is what keeps us all within the bounds of ordinance, and saves the children of fortune from the envious uprisings of the poor.
Strona 244 - Well! he may not count it, and a kind Heaven may not count it; but it is being counted none the less. Down among his nerve-cells and fibres the molecules are counting it, registering and storing it up to be used against him when the next temptation comes.
Strona 245 - ... death, the girl herself refused to stay. Anxious inquiries were then, of course, made concerning the pastor's habits, and the solution of the phenomenon was soon obtained.

Strona 244 - ... in a word, from which the man can by-and-by no more escape than his coat-sleeve can suddenly fall into a new set of folds. On the whole, it is best he should not escape. It is well for the world that in most of us, by the age of thirty, the character has set like plaster, and will never soften again.
Strona 121 - Arms of old were hands nails and teeth and stones and boughs broken off from the forests, and flame and fire, as soon as they had become known. Afterwards the force of iron and copper was discovered ; and the use of copper was known before that of iron, as its nature is easier to work and it is found in greater quantity.
Strona 52 - What a detestable feeling this fluttering of the heart is! I know it is nothing organic, and that it is entirely nervous; but the sickening effects of it are dispiriting to a degree. Is it the body brings it on the mind, or the mind that inflicts...
Strona 51 - No foxhunter ever prepared himself for the field by more substantial appliances. His table was always provided, in addition to the usually plentiful delicacies of a Scotch breakfast, with some solid article, on which he did most lusty...
