It seems certain that almost all our major problems involve human behavior, and they cannot be solved by physical and biological technology alone. What is needed is a technology of behavior, but we have been slow to develop the science from which such a technology might be drawn. One difficulty is that almost all of what is called behavioral science continues to trace behavior to states of mind, feelings, traits of character, human nature, and so on. Physics and biology once followed similar practices and advanced only when they discarded them. The behavioral sciences have been slow to change partly because the explanatory items often seem to be directly observed and partly because other kinds of explanations have been hard to find. The environment is obviously important, but its role has remained obscure. It does not push or pull, it selects, and this function is difficult to discover and analyze.

参考答案

无疑，人类一切重大的问题几乎都涉及行为，单靠物理和生物技术，是无法解决这些问题的。目前我们需要的是行为技术，但在行为技术赖以衍生的行为科学方面，我们进展缓慢。困难之一在于几乎所有的所谓行为科学仍然从心态、情感、性格特征、人性等方面去寻找行为的根源。人们在研究物理学和生物学时，曾采用相近的做法，只有在抛弃这些做法之后，这两门科学才得以向前发展。行为科学之所以发展缓慢，部分原因在于其解释似乎往往是直接观察得到的，部分原因则在于其他种类一直很难找到。毫无疑问，环境是重要的，但人们对其作用一直不甚明了。它不具备推动或牵引的作用，它只是选择，而这一作用难以发现也难以分析。
