A still great voice: The golden sovereignty of Science and Human Behavior.

And now, I will unclasp a secret book,
And to your quick-conceiving discontents
I'll read you matter deep and dangerous,
As full of peril and adventurous spirit
As to o'erwalk a current roaring loud
On the unsteadfast footing of a spear.
Shakespeare, Act 1, Scene 3, Henry IV, Part 1
