Within ourselves, we strangers are thereto.

We seek to know the moving of each sphere,

And the strange cause of th' ebbs and floods of Nile;

But of that Clock, which in our breasts we bear,

The subtle motions we forget the while!

We that acquaint ourselves with every zone,

And pass both tropics, and behold both poles;

When we come home, are to ourselves unknown

And unacquainted still with our own souls!

We study Speech, but others we persuade;
