So spake the Fiend, and with necessity, — Necessity

"A wise man never refuses anything to necessity."

"Necessity relieves us from the embarrassment of choice."

"Now sit we close about this taper here, And call in question our necessities."

"Freedom is only necessity understood."

"The art of our necessities is strange, That can make vile things precious."

"Art imitates nature, and necessity is the mother of invention."
