Perhaps the most loathed words that a child can hear growing up are the words; "Because I said so!" And up until recently I would have agreed with their displeasure. After all, isn't uttering such a phrase practically the equivalent of a religious person preaching that one should just accept this or that doctrine because… well… it's a mystery. This has always seemed to me (and still does) to be a bit of a dodge. I accept it, so you should too. That is not to say that there are not occasions where one ultimately needs to weigh the evidence and be willing to take a leap of faith, but the fact that something is "mysterious" and profound should not substitute for thinking. In any case, I used to believe that the only sort of person that would say such things was the type of person who never considered the reason behind the rules and was simply using their power and authority to mindlessly perpetuate something they themselves didn't understand. And while this may be the case in some instances, I have come to discover the hard way that there are also some very good reasons for saying those dreaded words.
The ability to be docile and flexible in spirit may not have the immediate effect of being pleasing, but in time it is the surest and most effective means of happiness. The virtue of obedience, if I may say it, makes one existentially agile, and ultimately allows them to be able to adapt to any set of circumstances. It is the one who demands to fully understand everything before he acts who he may never act at all.
