Here is Charlotte Mason describing the benefits of her way of education:
Let me try to indicate some of the advantages of the theory I am urging. It fits all ages and abilities. It satisfies brilliant children and discovers intelligence in the dull. It secures attention, interest, concentration, without effort on the part of teacher or taught.
Children, I think, all children, so taught express themselves in forcible and fluent English and use a copious vocabulary. Parents become interested in the schoolroom work, and find their children delightful companions.
Children show delight in books and manifest a genuine love of knowledge. Children taught according to this method do exceptionally well at any school.
