　　“Since science and technology are becoming more and more essential to modern society, schools should devote more time to teaching science and technology and less to teaching the arts and humanities.”

　　In conclusion, schools should not devote less time to the arts and humanities. These areas of study augment and enhance learning in mathematics and science, as well as helping to preserve the richness of our entire human legacy while inspiring us to further it. Moreover, disciplines within the humanities provide methods and contexts for evaluating the morality of our technology and for determining its proper direction.
