Love, Hope, and Joy, fair pleasure's smiling train, Hate, Fear, and Grief, the family of pain, These mix'd with art, and to due bounds confin'd Make and maintain the balance of the mind.
Trace Science, then, with Modesty thy guide,
First strip off all her equipage of Pride,
Deduct what is but Vanity or Dress,
Or Learning's Luxury or idleness,
Or tricks, to show the stretch of the human brain
Mere curious pleasure or ingenious pain.
