many negative emotions can actually be positive when shed under a different light.
As A. Pope put it:
As fruits, ungrateful to the planter's care,
On savage stocks inserted, learn to bear;
The surest virtues thus from passions shoot,
Wild nature's vigor working at the root.
What crops of wit and honesty appear
From spleen, from obstinacy, hate or fear!
See anger, zeal and fortitude supply;
Ev'n av'rice, prudence; sloth, philosophy;
Lust, thro' some certain strainers well refin'd,
Is gentle love, and charms all womankind;
Envy, to which th' ignoble mind's a slave,
Is emulation in the learn'd or brave;
Nor virtue, male or female, can we name,
But what will grow on pride, or grow on shame.
Thus nature gives us (let it check our pride)
The virtue nearest to our vice ally'd:
Reason the byas turns to good from ill,
And Nero reigns a Titus, if he will.
The fiery soul abhorr'd in Catiline,
In Decius charms, in Curtius is divine:
The same ambition can destroy or save,
And makes a patriot as it makes a knave.
This light and darkness in our chaos join'd,
What shall divide? The God within the mind.
Extremes in nature equal ends produce,
In man they join to some mysterious use;
Tho' each by turns the other's bound invade,
As, in some well-wrought picture, light and shade,
And oft so mix, the diff'rence is too nice
Where ends the virtue or begins the vice.
Fools! who from hence into the notion fall,
That vice or virtue there is none at all.
If white and black blend, soften, and unite
A thousand ways, is there no black or white?
Ask your own heart, and nothing is so plain;
'Tis to mistake them, costs the time and pain.
