While education has many purposes along with being of immense value for the improvement and advancement of society, the most fundamental thing that any good education must address is morality and thereby one's perspective of life itself. That is to say, it's great that through teachers, application, books, tools, classes, discussions, thinking, and so on and so forth, that we can bring forth to each succeeding generation, better engineers, better scientists, better doctors, and better educated people, but it isn't good enough to simply have smarter people if they have little or no moral compass to correctly steer their life upon, for the greatest danger in any world, isn’t any particular individual intent upon evil, but a particular individual that is well schooled, charismatic, ruthless, driven, and persuasive, that thereby has the ability to lead many, many people to do evil things against the good of society.
There are many people, for whatever vacuous reason, that believe that there isn't a known truth, or that truth is relative, or all sorts of basic philosophies built upon deceptions and falsehoods that persuade them to believe whatever convenient thing that it is for them to believe, yet, just studying children as they interact and play, clearly shows that there is one very basic truth that all are ingrained with, and it is this truth, that we should always keep front and center. For instance, when one child bullies another child, does the teacher encourage this behavior as being something that should be emulated; or when one child refuses to share with another child, does the teacher applaud such behavior; or do teachers encourage and admire liars, cheaters, hatred, and disruption? The very basic answer is no, because most people believe intuitively that life should be fair, equal, just, and that we should deal with others with respect and courtesy, yet, looking around at how often adults interact on a business and personal level, indicates that many people have put aside such concerns in order to get ahead, or to get over on somebody else, or to just be selfish, for the most basic truth of them all is that we should treat others the same way that we wish to be treated ourselves.
It is imperative within any education system, supported and aided by the state, that proper morality and ethics be taught to children within that system, and further should continue to be taught to those that then attend higher education. It isn't good enough to simply tell people that certain things and certain actions are wrong, for children are inquisitive, and adults question just about everything, so that, there needs to be an interplay, which allows students to begin to understand empathy, other perspectives, as well as the importance of integrity, honor, reciprocity, and respect.
It's unfair to expect that people will do the right thing, if they don't really know, if they don't really understand, if they don't really comprehend, what the right thing is to do and why that is the right thing to do in the first place. That is why any educational system that lacks the fortitude to teach basic morals and to impress these upon their charges, has failed those students. Our educational system has an inherent obligation to teach children how to think, and within that thinking, why it is important to think things through and to thereby do the right things, for if we can't accomplish that, we shouldn't expect the world to become a better place.
