There is no such thing as educational value in the abstract. The notion that some subjects and methods and that acquaintance with certain facts and truths possess educational value in and of themselves is the reason why traditional education reduced the material of education so largely to a diet of predigested materials.
Let education kindle only those which are truly beneficial
to the human species; let it favour those alone which are really necessary to the maintenance of society. The passions of man are dangerous, only because every thing conspires to give them an evil direction.
