Human beings are animals. We breathe, eat and digest, and reproduce the same life 1 common to all animals. In a biological laboratory, rats, monkeys, and humans seem very much the same.
However, biological understanding is not enough:2 itself, it can never tell us what human beings are. 3 to our physical equipment—the naked human body—we are not an 4 animal. We are tropical creatures, 5 hairless and sensitive to cold. We are not fast and have neither claws nor sharp teeth to defend ourselves. We need a lot of food but have almost no physical equipment to help us get it. In the purely physical 6, our species seems a poor 7 for survival.
But we have survived—survived and multiplied and 8 the earth. Some day we will have a 9 living on the moon, a place with neither air nor water and with temperatures that turn gases into solids. How can we have done all these things? Part of the answer is physical. 10 its limitations, our physical equipment has some important 11. We have excellent vision and hands that can 12 objects with a precision unmatched by any other 13. Most importantly, we have a large brain with an almost 14 number of neural 15.
We have used this physical equipment to create culture, the key to our survival and success. If we live in the Arctic, we supply the warmth our tropical bodies need 16 clothing, shelter, and 17 heat. If a million people want to live in a desert that supplies natural food for only a few hundred, we find water to grow food and 18 deficits by transporting supplies from distant places. Inhabitants of our eventual moon colony will bring their own food and oxygen and then create an artificial earth environment to supply necessities. With culture, we can overcome our natural limitations.
It was not always 19. Our distant ancestors were just animals, faced with the limits of their physical equipment. They had no 20 and lacked the physical capacity to use it.
