If our ancestral legacy is a good one, our picture blocks will be numerous and it will be possible for the proper system of education, aided by a suitable environment, to arrange them into many designs. If, on the other hand, our heredity did not endow us abundantly the number of our picture blocks may be limited to three or four, and they will be easily arranged so as to form a simple picture. The one represents a child whom heredity has richly endowed, the other one whom it has meagerly supplied with innate[32] possibilities. Heredity therefore dictates the function of education; and the school-master can only fashion the picture put there. If the ancestral blocks are not there with which to make an elaborate picture he must content himself with what is there,--he or his art cannot create others. When he congratulates himself on achieving a wonderful result in graduating a particularly brilliant student, he is taking to himself unmerited honors. If his individual ability is responsible in one instance, why not apply the same system to all pupils? If this system is responsible for the brilliancy of one pupil, why does not the same system make all brilliant? The reader knows the answer,--because heredity did not endow them equally. Men are not born equal, despite the Declaration of Independence. The school-master is not responsible for the apt and the inapt pupil. He is responsible for his system which dictates how he will differentiate between the apt and the inapt pupil, in order to achieve the best results without injustice to either.
