No spiritual mind remains within itself; it is always aspiring and going beyond its own strength.

A hair shirt does not always render those chaste who wear it.

All the fame you should look for in life is to have lived it quietly.

We took advantage of [the Indians'] ignorance and inexperience to incline them the more easily toward treachery, lewdness, avarice, and every sort of inhumanity and cruelty, after the example and pattern of our ways.

So it is with minds. Unless you keep them busy with some definite subject that will bridle and control them, they throw themselves in disorder hither and yon in the vague field of imagination... And there is no mad or idle fancy that they do not bring forth in the agitation.

The least strained and most natural ways of the soul are the most beautiful; the best occupations are the least forced.

Men do not know the natural infirmity of their mind: it does nothing but ferret and quest, and keeps incessantly whirling around, building up and becoming entangled in its own work, like silkworms, and is suffocated in it. A mouse in a pitch barrel...thinks it notices from a distance some sort of glimmer of imaginary light and truth; but while running toward it, it is crossed by so many difficulties and obstacles, and diverted by so many new quests, that it strays from the road, bewildered.
