一杯咖啡的第二个维度与其作为药物的用途有关。咖啡含有咖啡因，这是一种对大脑有刺激作用的药物。对许多人来说，这就是他们喝咖啡的原因。在社会学上有趣的是，为什么咖啡成瘾者在西方文化中不被视为吸毒者，尽管他们可能在其他文化中。与酒精一样，咖啡是一种社会可接受的药物，而大麻则不然。然而，在其他文化中，大麻的使用是可以忍受的，但咖啡和酒精的消费都是不受欢迎的。不过，一杯咖啡的第三个维度与社会和经济关系紧密相关。咖啡的种植，包装，分销和营销是影响这些文化中的许多文化，社会群体和组织的全球性企业。这些东西经常发生在距离咖啡饮用者数千英里的地方。我们生活的许多方面现在都处于全球化的贸易和通讯中，研究这些全球交易对社会学家来说非常重要。米尔斯在他的书中讨论过社会学想象的另一个方面，他最重视这一点，这是我们未来的可能性。社会学不仅帮助我们分析当前和现有的社会生活模式，而且还有助于我们看到一些可能的未来对我们开放。通过社会学的想象，我们不仅可以看到什么是真实的，而且我们可以看到，如果我们想要这样做，那么什么才能成为现实。

The second dimension of a cup of coffee is related to its use as a drug. Coffee contains caffeine, a drug that stimulates the brain. For many people, this is why they drink coffee. It is interesting in sociology why coffee addicts are not considered drug users in Western culture, although they may be in other cultures. Like alcohol, coffee is a socially acceptable drug, while marijuana is not. However, in other cultures, the use of marijuana is tolerable, but the consumption of coffee and alcohol is unpopular. However, the third dimension of a cup of coffee is closely related to social and economic relationships. The cultivation, packaging, distribution and marketing of coffee is a global enterprise that influences many cultures, social groups and organizations in these cultures. These things often happen thousands of miles from coffee drinkers. Many aspects of our lives are now in global trade and communications, and studying these global deals is very important to sociologists. Mills discussed another aspect of sociological imagination in his book. He values this most, and this is our future possibility. Sociology not only helps us analyze current and existing social life patterns, but also helps us see some possible futures open to us. Through sociological imagination, we can not only see what is real, but we can see that if we want to do so, then what can become a reality.
