No bird soars too high, if he soars with his own wings.
Prisons are built with stones of Law, Brothels with bricks of religion.
Joys impregnate.  Sorrows bring forth.
Always be ready to speak your mind, and a base man will avoid you.
The eagle never lost so much time as when he submitted to learn of the crow.
Expect poison from standing water.
Damn braces.  Bless relaxes.

If the doors of perception were cleansed every thing would appear to man as it is, infinite.
For man has closed himself up, till he sees all things thro' narrow chinks of his cavern.

The man who never alters his opinions is like standing water, & breeds reptiles of the mind.

-William Blake, from The Marriage of Heaven and Hell.
