In the next century we’ll be able to alter our DNA radically, encoding our visions and vanities while concocting new life-forms. When Dr. Frankenstein made his monster, he wrestled with the moral issue of whether he should allow it to reproduce, "Had I the right, for my own benefit, to inflict the curse upon everlasting generations" Will such questions require us to develop new moral philosophies
Probably not. Instead, we’ll reach again for a time-tested moral concept, one sometimes called the Golden Rule and which Kant, the millennium’s most prudent moralist, conjured up into a categorical imperative: Do unto others as you would have them do unto you; treat each person as an individual rather than as a means to some end.
Under this moral precept we should recoil at human cloning, because it inevitably entails using humans as means to other humans’ ends and valuing them as copies of others we loved or as collections of body parts, not as individuals in their own right. We should also draw a line, however fuzzy, that would permit using genetic engineering to cure diseases and disabilities but not to change the personal attributes that make someone an individual (IQ, physical appearance, gender and uality).
The biotech age will also give us more reason to guard our personal privacy. Aldous Huxley in Brave New World, got it wrong: rather than centralizing power in the hands of the state, DNA technology has empowered individuals and families. But the state will have an important role, sure that no one, including insurance companies, can look at our genetic data without our permission or use it to discriminate against us.
Then we can get ready for the breakthroughs that could come at the end of the next century and the technology is comparable to mapping our genes: plotting the 10 billion or more neurons of our brain. With that information we might someday be able to create artificial intelces that think and experience consciousness in ways that are indistinguishable from a human brain. ually we might be able to replicate our own minds in a "dry-ware" machine, so that we could live on without the "wet-ware" of a biological brain and body. The 20th century’s revolution in infotechnology will thereby merge with the 21st century’s revolution in biotechnology. But this is science fiction. Let’s turn the page now and get back to real science.

A.
As one works with color in a practical, or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile, changeable thing (1) to a large extent on the relationship of the color (2) other colors (3) simultaneously. It is not (4) in its relation to the direct stimulus which (5) it. On the other hand, the properties of surfaces that give (6) to color do not seem to change greatly under a wide variety of illumination color, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to be (7) in large part to the mechanism of color (8) .
B.
When the eye is (9) to a colored area, there is an immediate readjustment of the (10) of the eye to color in and around the area (11) . This readjustment does not promptly affect the color seen but usually does affect the next area to which the (12) is shifted. The longer the time of viewing, the higher the (13) , and the larger the area, the greater the effect will be (14) its persistence in the (15) viewing situation. As indicated by the work of Wright and Schouten, it appears that, at (16) for a first approximation, full adaptation takes place over (17) time if the adapting source is moderately bright and the eye has been in (18) darkness just previously. Also, (19) of the persistence of the effect if the eye is shifted around from one object to another, all of which are at similar brightness or have similar colors, the adaptation will tend to become (20) over the whole eye.

A.
The lake lay before me, blue and peaceful, in the evening (36) . On either side the mountains rose sharply surrounding it in a kind of bowl. A few sheep (37) their sides here and there and a cow was (38) with eating on the lower slopes. The place was so far away, so untouched by human work that it seemed the very place to (39) . Even Higgs, I thought, won’t be able to find me here.
B.
I sat down by the edge of the lake, and pulled (40) my shoes and socks, put my (41) in the water. It was cold, like ice. After a moment I (42) over and spread some of the (43) on my hot face. I could see myself faintly in the water staring at me like a (44) .
C.
I realized suddenly how (45) I was of running away. Surely, I thought I could live here for a few days, out of (46) of Higgs and his men. While I tried to (47) some plans for the future, I found a tiny cottage on the far side of the (48) with some smoke coming from its roof. I still had a little money. Perhaps they would give me a (49) and some food.
D.
As I watched, a man came out of the house and down to a little (50) at the lakeside. He got into it and began to move (51) towards my side. I could not see his (52) at first. He continued calmly (53) the lake, and when he was about halfway, he rested his oars and the boat drifted into a patch of sunlight. He (54) a hand in a friendly way of greeting. I Was about to raise mine, (55) all at once, I saw his face clearly, it was Higgs!
