Every spirit builds itself a house; and beyond its house a world; and beyond its world, a heaven. Know then, that the world exists for you. For you is the phenomenon perfect. What we are, that only can we see. All that Adam had, all that Caesar could, you have and can do. Adam called his house, heaven and earth; Caesar called his house, Rome; you perhaps call yours, a cobler's trade; a hundred acres of ploughed land; or a scholar's garret. Yet line for line and point for point, your dominion is as great as theirs, though without fine names. Build, therefore, your own world.

Nature suffers nothing to remain in her kingdom which cannot help itself.

What art can paint or gild any object in after life with the glow which nature gives to the first baubles of childhood? St. Peter's cannot have the magical power over us that the red and gold covers of our first picture-book possessed.

Murder in the murderer is no such ruinous thought as poets and romancers will have it; it does not unsettle him, or fright him from his ordinary notice of trifles; it is an act quite easy to be contemplated.

Nature is thoroughly mediate. It is made to serve. It receives the dominion of man as meekly as the ass on which the Saviour rode.It offers all its kingdoms to man as the raw material which he may mould into what is useful. Man is never weary of working it up.

A weed is a plant we've found no use for yet.

I shun father and mother and wife and brother, when my genius calls me.
