There is a history in all men’s lives,

Figuring the nature of the times deceased;

The which observed, a man may prophesy,

With a near aim, of the main chance of things

As yet not come to life; which in their seeds

And weak beginnings lie intreasured.

Shakespeare, 2 Henry IV., III. i.

They pass through whirl-pools, and deep woes do shun,

Who the event weigh, ‘ere the action’s done.

Webster, Duchess of Malfi, II. 4.
