The need for development of the senses in everyday life
A person studies to be a chef. She may be able to read the recipe fluently, understand perfectly well what ingredients she requires and the procedure or method of combining the ingredients together to prepare the meal. Yet when the time comes for her to decide by taste when a certain seasoning is to be added slightly more for that added distinctive flavor or sight as to when the the food or cake is perfectly cooked, her performance will break down if her senses have not been adequately prepared.
Likewise people in the food industry depend on their sense of taste to perfect their food products. Security guards have to attune their sense of hearing in order to serve and protect. Perfume manufacturers depend on their keen sense of smell to bring to the consumer a fragrant range of perfumes.
Even the doctor may be highly intelligent. After he has mastered profound theories, even he finds himself constrained to undertake the task of learning to recognize by virtue of his senses the symptoms of different diseases, in order to put his theories into useful practice. He is therefore like a novice as he methodically proceeds through feeling, tapping and listening to recognize the vibrations, tones, murmurs and various other sounds to assist him to form a diagnosis. The intellectual training of the doctor thus proves powerless because of his inadequately trained senses.
