"Consideration, like an angel came And whippd the offending Adam out of him, Leaving his body as a paradise, To envelope and contain celestial spirits."
"What you have said I will consider; what you have to say I will with patience hear, and find a time Both meet to hear and answer such high things."

Consideration is a concept of English common law and is a necessity for simple contracts but not for special contracts. The concept has been adopted by other common law jurisdictions. It is commonly referred to as one of the six or seven elements of a contract.
