Genesis 25:33

33 And Jacob said, Swear to me this day; and he sware unto him: and he sold his birthright unto Jacob.

CS Lewison Genesis 25:29-34AD 1963
The longer I looked into it the more I came to suspect that I was perceiving a universal law... It may be stated as follows: every preference of a small good to a great, or a partial good to a total good, involves the loss of the small or partial good for which the sacrifice was made.

Apparently the world is made that way. If Esau really got the pottage in return for his birthright, then Esau was a lucky exception. You can't get second things by putting them first; you can get second things only by putting first things first. From which it would follow that the question, What things are first? is of concern not only to philosophers but to everyone.
