“The true object of all human life is play.”

“Man is a creature of habit and repetition.”

“Life is a series of relapses and recoveries.”

“The love of nature is a passion for the beautiful in the external world, and the love of science is a passion for the beautiful in the intellectual world.”

“The study of the child is the one thing needful.”

“The best preparation for a life of service is a life of culture.”

“Childhood is the paradise of the individual.”

“The teacher must be the master of the art of abbreviation.”

“The highest culture is to speak no ill.”

“The contents of the child's mind are not unimportant, but the way in which he uses them is the all-important thing.”
