The Commercial Revolution was not confined, of course, to the growth of trade and banking. Included in it also were fundamental changes in methods of production. The system of manufacture developed by the craft guilds in the later Middle Ages was rapidly becoming defunct. The guilds themselves, dominated by the master craftsmen, had grown selfish and exclusive. Membership in them was commonly restricted to a few privileged families. Besides, they were so completely choked by tradition that they were unable to make adjustments to changing conditions. Moreover, new industries had sprung up entirely outside the guild system. Characteristic examples were mining and smelting and the woolen industry. The rapid development of these enterprises was stimulated by technical advances, such as the invention of the spinning wheel and the discovery of a new method of making brass, which saved about half of the fuel previously used. In the mining and smelting industries a form of organization was adopted similar to that which has prevailed ever since.
But the most typical form of industrial production in the Commercial Revolution was the domestic system, developed first of all in the woolen industry. The domestic system derives its name from the fact that the work was done in the homes of industrial artisans instead of in the shop of a master craftsman. Since the various jobs in the manufacture of a product were given out on contract, the system is also known as the putting out system. Notwithstanding the petty scale of production, the organization was basically capitalistic. The raw material was purchased by an entrepreneur and assigned to individual worker, each of whom would complete his allotted task for a stipulated payment. In the case of the woolen industry the yarn would be given out first of all to the spinners, then to the weavers, fullers, and dyer in succession. When the cloth was finally finished, it would be taken by the clothier and sold in the open market for the highest price it would bring.

Emotion is a feeling about or reaction to certain important events or thoughts. People enjoy feeling such pleasant emotions as love, happiness, and contentment. They often try to avoid feeling unpleasant emotions, such as loneliness, worry, and grief.
Individuals communicate most of their emotions by means of words, a variety of sounds, facial expressions, and gestures. For example, anger causes many people to frown, make a fist, and yell. People learn ways of showing some of their emotions from members of their society, though heredity (遗传) may determine some emotional behavior. Research has shown that different isolated peoples show emotions by means of similar facial expressions.
Charles Darwin, famous for the theory of natural selection, also studied emotion. Darwin said in 1872 that emotional behavior originally served both as an aid to survival and as a method of communicating intentions. According to the James-Lange theory of emotions developed in the 1880s, people feel emotions only if aware of their own internal physical reactions to events, such as increased heart rate or blood pressure. But this theory was not upheld by research on cats that had their nervous systems damaged. The cats could not feel their body’s internal changes, but they showed normal emotional behavior. John B. Watson, an American psychologist who helped found the school of psychology called behaviorism, observed that babies stimulated by certain events showed three basic emotions--fear, anger, and love. Watson’s view has been challenged frequently since he proposed it in 1919.
The most widely accepted view is that emotions occur as a complex sequence of events. The sequence begins when a person encounters an important event or thought. The person’s interpretation of the encounter determines the feeling that is likely to follow. For example, someone who encounters a bear in the woods would probably interpret the event as dangerous. The sense of danger would cause the individual to feel fear. Each feeling is followed by physical changes and desires to take action, which are responses to the event that started the sequence. Thus, a person who met a bear would probably run away.
Several American psychologists independently developed the theory that there are eight basic emotions. These emotions--which can exist at various levels of intensity--are anger, fear, joy, sadness, acceptance, disgusts, surprise, and interest or curiosity. They combine to form all other emotions, just as certain basic colors produce all others.
