am lived in peace with all the animals. God gave Adam eternal life. But Adam was lonely in the gar den, so God made Eve. When Adam was asleep one night, God took a rib from him and made Eve, the first woman. Adam was happy when he woke up the next morning and found Eve beside him. God said to them, "Here in the Garden you have everything. But you cannot have one thing: you cannot eat the apples from the Tree of Knowledge."

One day Satan came to the Garden. He changed into a snake and went to live in the Tree of Knowledge. When Eve came near the tree one day, the snake called her. He gave her an apple and said," Take this apple and eat it. Don' t listen to the God. Eat it. "After Eve took a bite, she the apple to Adam. He was afraid, but Eve repeated again and again: "It' s good. Here, eat it. Why not？" So he finally ate the apple.

Before they ate the apple; Adam and Eve didn' t know that they were naked. But now they were ashamed and covered their bodies with leaves. God was angry with them. He said, "Leave the Gar den. You cannot stay here."

When Adam and Eve left the garden, they had their first experience of pain and hard work in the cold hard world outside.

The University as Business

A number of colleges and universities have announced steep

tuition increases for next year much steeper than the current,

very low, rate of inflation. They say the increases are needed because

of a loss in value of university endowments' heavily investing in common 1

stock. I am skeptical. A business firm chooses the price that maximizes

its net revenues, irrespective fluctuations in income; and increasingly the 2

outlook of universities in the United States is indistinguishable from those of 3

business firms. The rise in tuitions mayreflect the fact economic uncertainty 4

increases the demand for education. The biggest cost of being

in the school is foregoing income from a job (this isprimarily a factor in 5

graduate and professional-school tuition); the poor one' s job prospects, 6

the more sense it makes to reallocate time from the job market to education,

in order to make oneself more marketable. The ways which universities make themselves attractive to students 7

include soft majors, student evaluations of teachers, giving students

a governance role, and eliminate required courses. 8

Sky-high tuitions have caused universities to regard their students as

customers. Just as business firms sometimes collude to shorten the 9

rigors of competition, universities collude to minimize the cost to them of the

athletes whom they recruit in order to stimulate alumni donations, so the best

athletes now often bypass higher education in order to obtain salaries earlier

from professional teams. And until they were stopped by the antitrust authorities,

the Ivy League schools colluded to limit competition for the best students, by

agreeing not to award scholarships on the basis of merit rather than purely

of need-just like business firms agreeing not to give discounts on their best 10

customer.
