恩格斯曾说过一句话，大概意思是社会的进步是由极左的革命失败后带来的。谁知道原话？译成英文更好！

恩格斯说：“在社会发展某个很早阶段产生了这样一种需要，把每天重复的生产、分配和交换商品的行为用一个共同规则概括起来---这个规则首先表现为习惯，后来便成为法律。随着法律的产生，就必然产生出以维护法律为职责的公共权力机关---即国家。”
试述这段话说明的基本原理，并运用法理学相关理论加以论述

翻译:Engels said : "In a very early stage of social development have such a need, the daily repetition of the production, distribution and exchange of commodities act in a common rule summation --- the first performance of customary rules and subsequently became law. As a law, It will inevitably produce to safeguard the legal authority to mandate public --- that country. "
