[Skull]

We figure to ourselves Intellect as an ethereal sea, which ebbs and flows, which surges and washes hither and thither, carrying its whole virtue into every creek and inlet which it bathes. To this sea every human house has a water front. But this force, creating nature, visiting whom it will and withdrawing from whom it will, making day where it comes and leaving night when it departs, is no fee or property of man or angel. It is as the light, public and entire to each, and on the same terms.

R.W. Emerson, "Natural History of Intellect"
