Professor Llewellyn claims
that the number of promises made in society has risen over time from early
history to the present. He claims that
reliance on promises has grown as the number of promises made has grown. He claims that in early history, the rule for
enforcing promises was that they shall not be enforced unless a specific good
reason is shown. Now, Llewellyn says,
promises are enforced unless good reason is shown that they shouldn’t be
enforced.
This is not to say that all
promises are enforced. But more and more
promises are being enforced over time.
