One might ask: what is right and what is wrong? No one can stamp any deed as right or wrong. But there is a natural sense in one which distinguishes between right and wrong, just or unjust, a sense even in the child. One sees the line and color in art or decoration. One sees if the tablecloth is not laid straight on the table and when a line that should be straight is not straight. Even a child knows when things should be harmonious in line and color; a child normally loves harmony in line and color. There is a natural tendency in the heart of each person, the natural instrument that the masons use for building a house.
