Robert Browning Quote

It's wiser being good than bad;
It's safer being meek than fierce;
It's fitter being sane than mad.
My own hope is, a sun will pierce
The thickest cloud earth ever stretched;
That after Last returns the First,
Though a wide compass round be fetched;
That what began best can't end worst,
Nor what God blessed once prove accurst.

Apparent Failure, vii. - Bartlett's Familiar Quotations, 10th ed. (1919)
