Pain and pleasure no more tally in our sense than red and green;
Still, without what seems such mortal's pleasure, pain, my life were lost
—Life, my whole sole chance to prove—although at man's apparent cost—
What is beauteous and what ugly, right to strive for, right to shun,
Fit to help and fit to hinder,—prove my forces every one,
Good and evil,—learn life's lesson, hate of evil, love of good,
As 't is set me, understand so much as may be understood—
Solve the problem: "From thine apprehended scheme of things, deduce
Praise or blame of its contriver, shown a niggard or profuse
In each good or evil issue! nor miscalculate alike
