The Hand-Brain Connection

In some languages the corresponding expressions for understand make a strong reference to motor activities of the hand. The German word “Begreifen” means to comprehend and know the nature or meaning of something. The root of the word, greifen, means to touch or grasp something with your hands. We not only manipulate the world with our hands, but also use feedback from this touch sensation to construct our inner world. Your hands know more than what you know!
