A school is a high place of knowledge. It is an institution that produces and distills expertise in various fields. It shapes the vision of the elites who rule the nations. She educates, she creates social classes.
School And Posterity
History has made a place of choice for the unforgettable inventors and scientists who have made significant discoveries or developed grand theories to explain phenomena that are beyond the comprehension of ordinary mortals. Thus we all know today Einstein, Galileo, Newton, Darwin or 
Hawkins, to name only those there. They have left an immeasurable good to humanity and posterity. These are high figures of the success of good school education.
School and knowledge
In keeping with scientific and technological progress, the school offers a wide range of expertise. Theories abound, trying to explain phenomena of life, inert and matter in all its forms: solid, liquid, gaseous. The knowledge is structured and presented in the form of courses or disciplines that the model student must assimilate and return in the best way to have good grades. Without this knowledge shaped over the years, we would not understand our world. Without this knowledge, we would not have had all the progress that our civilization has benefited, and that has made the world as it is today (our cities, treatments for diseases, etc.).
School and social conduct
A society, whatever it is, needs values. These values, in our modern society, for example, are instilled in the future generation through schools. School education models and simplifies these values to make them understandable even to the still stammering mind of a child. Who does not 
remember civic education taught in primary school? Without forgetting those rhymes, fables, poems or songs that made our children’s hearts vibrate and introduced us to distinguish right from wrong. These acquired values shape the personality; teach us the rules and laws to respect, for a better society. The school harmoniously complements or reframes family education and street education.
Look around you. How many are these stars, yet wealthy, but who chained escapades, hiccups, and errors, often worthy of amateurs and “big kids”? What is most often their problem? Not having been to school A wealthy and influential man but without education, is a real public danger!
