The only advice I can give to the student is to study a subject for itself and use it exactly as stated, then form his own opinions. Study it with the purpose in mind of arriving at his own conclusions as to whether or not the tenets he has assimilated are correct and workable. Compare what you have learned with the known universe. Seek for the reasons behind a manifestation, and postulate the manner and in which direction the manifestation will likely proceed. Do not allow the authority of any one person or school of thought to create a foregone conclusion within your sphere of knowledge. Only with these principles of education in mind can you become a truly educated individual.
