Heaven is under our feet as well as over our heads.

To be awake is to be alive.

We can never have enough of nature. We must be refreshed by the sight of inexhaustible vigor.

I, on my side, require of every writer, first or last, a simple and sincere account of his own life, and not merely what he has heard of other men's lives; some such account as he would send to his kindred from a distant land; for if he has lived sincerely, it must have been in a distant land to me.

The mass of men lead lives of quiet desperation.

What the essential difference between man and woman is, that they should be thus attracted to one another, no one has satisfactorily answered. Perhaps we must acknowledge the justness of the distinction which assigns to man the sphere of wisdom, and to woman that of love, though neither belongs exclusively to either. Man is continually saying to woman, Why will you not be more wise? Woman is continually saying to man, Why will you not be more loving? It is not in their wills to be wise or to be loving; but, unless each is both wise and loving, there can be neither wisdom nor love.

If a man is alive, there is always danger that he may die, though the danger must be allowed to be less in proportion as he is dead-and-alive to begin with. A man sits as many risks as he runs.
