Then there are the natural conditions, such as the mother knowing the language of the little child who is not yet able to speak. His tears and his smiles, his looks explain to the mother his moods, his pleasures and displeasures, his aspirations and his wants. It is also known that the heart of the lover knows the pleasure and displeasure, the change of moods in the beloved without one word having been spoken. There are physicians who, through their experience in life, have become so advanced that before the patient has spoken one word they have already found out what is the complaint, what is the matter with the person. There are businessmen who are so engrossed in business that, as soon as a person has come to their shop, they know whether he will buy or whether he will go away without buying. What does this tell us? It shows us that, whatever be our walk in life, whatever be our profession, our business, our occupation - through it all there is a sense within us, a sense which can understand language without words.
