This story is probably apocryphal, but it illustrates well the attitudes of the time. (47) Many people accept Darwin's view of how we came into being that our bodies evolved through the process of natural selection acting on our genes. However, Darwin believed evolution was responsible for far more than just our physical characteristics. He saw it as the major influence in shaping our psychology. In- deed, he predicted that "in the distant future, psychology will be based on a new foundation". (48) To proponents of concepts like free will and personal responsibility, such an idea seems absurd. (49) Their research has revealed increasing evidence that the human mind is made up of innate mechanisms, which control everything from the way we perceive time and space, to how we learn survival techniques and choose mates. (50) Steven Pinker, Professor of Cognitive Science at the Massachusetts Institute of Technology, likens language ability to computer software, "children learn a new word every 90 minutes of their waking life for years, then they have to figure out how to string them together using a kind of mental computer program. The essence of human language is the ability to convey new ideas by putting words together in different combinations. Since we all have this language 'software' in our minds, we can figure out what others are saying by the meanings of the words and the order in which they are arranged." A. Today, we are more comfortable with out past. B. "And, if it is true, let us hope it does not become public knowledge." C. But a growing number of scientists are questioning the extent to which our behavior. is controlled by our culture. D. Many people are calling for controls on cloning immedicte1y before the practice is abused. E. The foundation was, of course, his theory of evolution. F. Nowhere is this more obvious than our innate ability to learn languages. (46)

In practice, what often happens is that a new theory is devised that is really an extension of the previous theory. For example, very accurate observations of the planet Mercury revealed a small difference between its motion and the predictions of Newton's theory of gravity. Einstein's general theory of relativity predicted a slightly different motion from Newton's theory. The fact that Einstein's predictions matched what was seen, while Newton's did not, was one of the crucial confirmations of the new theory. However, we still use Newton's theory for all practical purposes because the difference between its predictions and those of general relativity is very small in the situations that we normally deal with. (Newton's theory also. has the great advantage that it is much simpler to work with than Einstein's ! ) It turns out to be very difficult to devise a theory to describe the universe all in one go. Instead, we break the problem up into bits and invent a number of partial theories. Each of these partial theories describes and predicts a certain limited class of observations, neglecting the effects of other quantities, or representing them by simple sets of numbers. It may be that this approach is completely wrong. If everything in the universe depends on everything else in a fundamental way, it might be impossible to get close to a full solution by investigating parts of the problem in isolation. Nevertheless, it is certainly the way that we have made progress in the past. The classic example again is the Newtonian theory of gravity, which tells us that the gravitational force between two bodies depends only on one number associated with each body, its mass, but is otherwise independent of what the bodies are made of. Thus one does not need to have a theory of the structure and constitution of the sun and the planets in order to calculate their orbits: Today scientists describe the universe in terms of two basic partial theories-the general theory of relativity and quantum mechanics. They are the great intellectual achievements of the first half of this century. Unfortunately, however, these two theories are known to be inconsistent with each other-they cannot both be correct. One of the major endeavours in physics today, is the search for a new theory that will incorporate them both-a quantum theory of gravity. We do not yet have such a theory, and we may still be long way from having one, but we do already know many of the properties that it must have. According to the passage, why can't any physical theory be permanently established？ A．Such a theory is only suggested as a possible way of explaining an idea. B．The person proposing such a theory may be incompetent. C．Observations always disagree with predictions. D．Observations are always falsified by predictions.
