It is a terrible thing to be happy! How pleased we are with it! How all-sufficient we think it! How, being in possession of the false aim of life, happiness, we forget the true aim, duty!

In this world, which is so plainly the antechamber of another, there are no happy men. The true division of humanity is between those who live in light and those who live in darkness. Our aim must be to diminish the number of the latter and increase the number of the former. That is why we demand education and knowledge.

In winter there is no heat, no light, no noon, evening touches morning, there is fog, and mist, the window is frosted, and you cannot see clearly. The sky is but the mouth of a cave. The whole day is the cave.... Frightful season! Winter changes into stone the water of heaven and the heart of man.

Revery, which is thought in its nebulous state, borders closely upon the land of sleep, by which it is bounded as by a natural frontier.

One can no more keep the mind from returning to an idea than the sea from returning to a shore. For a sailor, this is called the tide; in the case of the guilty it is called remorse. God stirs up the soul as well as the ocean.

The book which the reader now holds in his hands, from one end to the other, as a whole and in its details, whatever gaps, exceptions, or weaknesses it may contain, treats of the advance from evil to good, from injustice to justice, from falsity to truth, from darkness to daylight, from blind appetite to conscience, from decay to life, from bestiality to duty, from Hell to Heaven, from limbo to God. Matter itself is the starting-point, and the point of arrival is the soul. Hydra at the beginning, an angel at the end.

Equality does not mean that all plants must grow to the same height - a society of tall grass and dwarf trees, a jostle of conflicting jealousies. It means, in civic terms, an equal outlet for all talents; in political terms, that all votes will carry the same weight; and in religious terms that all beliefs will enjoy equal rights.
