Look sharply after your own thoughts. They come unlooked for, like a new bird seen on your trees, and, if you turn to your usual task, disappear; and you shall never find that perception again; never, I say-but perhaps years, ages, and I know not what events and worlds my lie between you and its return.

Everything good is on the highway.

History is the action and reaction of these two, nature and thought.

Every wall is a door.

Do what you know and perception is converted into character.

Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.

I am become a transparent eyeball.
