The education process is as much about mental and character formation as it is about information and subjects. The formative value of the subjects we teach in school is as important as—if not more important than—the actual content. Math teaches logical, accurate, precise thinking; history teaches judgment, discernment, prudence; literature teaches sensitivity to the human condition; penmanship teaches the beginning student the basic skills of concentration, accuracy, correct spelling, and the patience and persistence required to do quality work. These mental habits, work habits, and skills transfer to every area of life. They distinguish the educated person from the uneducated.
