Genesis 25:32

This vice of gluttony delivered Adam up to death; by the pleasure of the appetite consummate evil was brought into the world. Through it Noah was mocked, Canaan was cursed, Esau was deprived of his birthright and married into a Canaanite family. Lot became his own son-in-law and father-in-law, by marrying his own daughter.

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.
