The end of education is not to teach, but to fit the mind for learning from its own consciousness and observation.... As the memory is trained by remembering, so is the reasoning power by reasoning; the imaginative by imagining; the analytic by analysing; the inventive by finding out. Let the education of the mind consist in calling out and exercising these faculties: never trouble yourself about giving knowledge -- train the mind -- keep it supplied with materials, and knowledge will come of itself.
