符号是一种思考的工具

Kenneth E. Iverson
IBM Thomas J. Watson Research Center

The importance of nomenclature, notation, and language as tools of thought has long been recognized.
人们早已认识到命名、符号、语言作为思维工具的重要性。

In chemistry and in botany, for example, the establishment of systems of nomenclature by Lavoisier and Linnaeus did much to stimulate and to channel later investigation.

例如，在化学和植物学中，拉瓦锡 和 林奈 建立的命名系统在很大程度上促进和引导了后来的研究。

Concerning language, George Boole in his Laws of Thought asserted
“That language is an instrument of human reason, and not merely a medium for the expression of thought, is a truth generally admitted.”
关于语言，乔治布尔曾在他的《思维定律/The Laws of Thought》中[1, p.24]写道：语言是一种人类理性的工具，而不仅仅是表达**的媒介；这是一种普遍承认的真理。

赞美APL：一种歌词式编程语言

Professor Alan J. Perlis / Yale University / First appeared in SIAM News, 1977-06. http://www.jsoftware.com/papers/perlis77.htm

Many reasons can be given for teaching one or more aspects of computer science (defined as the study of the set of phenomena arising around and because of the computer) to all university students. Probably every reader of this note supports some of these reasons. Let me list the few I find most important:

(1) 学会并且能够编写算法；
(2) 了解计算机的组织和构造方式；
(3) 熟练掌握至少一门编程语言；
(4) 通过系统设计来理解复杂度控制的必然性；

• (5) 体会计算机科学家对他们学科的热爱以及对科学发展的外在影响（对学生作为公民）。
  to appreciate the devotion of computer scientists to their subject and the exterior consequences (to the student as citizen) of the science’s development.

• 尽管计算机科学处理的是我们用数学方法研究其性质的符号对象，但它不能被教导为一种有序的发展，这种发展源于学生在成熟过程中已经直观地观察到的一些基本**，例如万有引力和电力。
  (大意是强调跟其他学科的区别？
  Even though computer science deals with symbolic objects whose nature we study mathematically, it cannot be taught as an orderly development arising from a few fundamental ideas whose existence the student has already observed intuitively during his maturation, such as gravitation and electricity.
