Human and
Culture{{/B}} Human beings are animals. We breathe, eat and
digest, and reproduce the same life processes common to all animals. In a
biological laboratory, rats, monkeys, and humans seem very much the
same. However, biological understanding is not enough:{{U}}
(51) {{/U}}itself, it can never tell us what human beings are.{{U}}
(52) {{/U}}to our physical equipment—the naked human body—we are not
an{{U}} (53) {{/U}}animal. We are tropical creatures, nearly 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{{U}} (54) {{/U}}, our species
seems a poor{{U}} (55) {{/U}}for survival. But we have
survived—survived and multiplied and{{U}} (56) {{/U}}the earth. Some day
we will have a{{U}} (57) {{/U}}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. In spite of its
limitations, our physical equipment has some important{{U}} (58) {{/U}}.
We have excellent vision and hands that can{{U}} (59) {{/U}}objects with
a precision unmatched by any other{{U}} (60) {{/U}}. Most importantly,
we have a large brain with an almost{{U}} (61) {{/U}}number of neural
connections. 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{{U}} (62) {{/U}}clothing,
shelter, and{{U}} (63) {{/U}}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{{U}} (64) {{/U}}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{{U}} (65) {{/U}}. Our distant ancestors were
just animals, faced with the limits of their physical equipment. They had no
culture and lacked the physical capacity to use
it.
