Quote by William Stern

"The child is not a miniature adult, but a being in the process of development."

"Psychology must study the whole person in their total environment."

"Intelligence is not fixed but develops through interaction with the world."

"The mind grows through activity and experience."

"I love my wife, but sometimes she drives me crazy."

"Love conquers all obstacles."

"Love is patient, love is kind."

"I'm not stupid, I'm just in love!"
