Certain Quote by Donald Knuth
“When certain concepts of TeX are introduced informally, general rules will be stated; afterwards you will find that the rules aren't strictly true. In general, the later chapters contain more reliable information than the earlier ones do. The author feels that this technique of deliberate lying will actually make it easier for you to learn the ideas. Once you understand a simple but false rule, it will not be hard to supplement that rule with its exceptions.”

![“[T]hough in all practical matters it is indispensable, either always or mostly, to follow custom, to do what is generally done, in theoretical matters it is simply untrue. In practical matters there is a right of the first occupant: what is established must be respected.
