“One of the main problems encountered in time travel is not that of accidentally becoming your own father or mother. There is no problem involved in becoming your own father or mother that a broadminded and well-adjusted family can’t cope with.”

“One of the major problems encountered in time travel is not that of becoming your own father or mother. There is no problem in becoming your own father or mother that a broad-minded and well-adjusted family can't cope with. There is no problem with changing the course of history—the course of history does not change because it all fits together like a jigsaw. All the important changes have happened before the things they were supposed to change and it all sorts itself out in the end.The major problem is simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner's Time Traveler's Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be descibed differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is futher complicated by the possibility of conducting conversations while you are actually traveling from one time to another with the intention of becoming your own mother or father.Most readers get as far as the Future Semiconditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up; and in fact in later aditions of the book all pages beyond this point have been left blank to save on printing costs.The Hitchhiker's Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term "Future Perfect" has been abandoned since it was discovered not to be.”

“Your parents were fighting machines and self-pitying machines. Your mother was programmed to bawl out your father for being a defective moneymaking machine, and your father was programmed to bawl out your mother for being a defective housekeeping machine. They were programmed to bawl each other out for being defective loving machines. Then your father was programmed to stomp out of the house and slam the door. This automatically turned your mother into a weeping machine. And your father would go down to the tavern where he would get drunk with some other drinking machines. Then all the drinking machines would go to a whorehouse and rent fucking machines. And then your father would drag himself home to become an apologizing machine. And your mother would become a very slow forgiving machine.”

“The best years of your life are the ones in which you decide your problems are your own. You do not blame them on your mother, the ecology, or the president. You realize that you control your own destiny.”

“There are two facts that all children need to disprove sooner or later; mother and father. If you go on believing in the fiction of your own parents, it is difficult to construct any narrative of your own.”

“Once you become aware that the main business that you are here for is to know God, most of life's problems fall into place of their own accord.”
