Human brain Quote by Thomas Homer-Dixon

““We can see how our world is, in many ways, becoming more complex, fast-paced, and unpredictable. As a result, the problems we face are getting more complicated as well, and (as in my thought experiment), we need longer and more elaborate sets of instructions for technologies and institutions that can effectively solve them. Or, to put it in terms of complexity theory: the greater complexity of our world requires greater complexity in our technologies and institutions. As the American complexity theorist Yaneer Bar-Yam writes, “We must understand that … human systems exist within an environment that places demands upon them. If the complexity of these demands exceeds the complexity of a system, the system will fail. Thus, those systems that survive must have a complexity sufficiently large to respond to the complexity of environmental demands.”3 The human brain is the ultimate source of the ideas, ingenuity, and sets of instructions we need to cope with this greater complexity. And it is, itself, a vastly complex system. Through a sophisticated set of senses, the brain receives a flood of information about the body’s internal state and its external environment. It interprets this information and commands appropriate responses. Although we think of the brain primarily in terms of its role in conscious thought and decision, it also handles a wide array of routine and unconscious tasks, from guiding motor activity to regulating visceral, endocrine, and somatic functions.4””
