The intellectual power, through words and things,Went sounding on a dim and perilous way!

Dreams, books, are each a world; and books, we know,
Are a substantial world, both pure and good:
Round these, with tendrils strong as flesh and blood,
Our pastime and our happiness will grow.

I am already kindly disposed towards you. My friendship it is not in my power to give: this is a gift which no man can make, it is not in our own power: a sound and healthy friendship is the growth of time and circumstance, it will spring up and thrive.

With an eye made quiet by the power of harmony, and the deep power of joy, we see into the life of things.

Love all, trust a few, do wrong to none; be able for thine enemy rather in power than use; and keep thy friend under thine own life's key; be checked for silence, but never taxed for speech

The rise of Islam offers perhaps the most impressive example in world history of the power of words to alter human behavior in sudden, surprising ways.
