Careful Words

obstruction (n.)

Ay, but to die, and go we know not where;

To lie in cold obstruction and to rot;

This sensible warm motion to become

A kneaded clod; and the delighted spirit

To bathe in fiery floods, or to reside

In thrilling region of thick-ribbed ice;

To be imprison'd in the viewless winds,

And blown with restless violence round about

The pendent world.

William Shakespeare (1564-1616): Measure for Measure. Act iii. Sc. 1.
