We have seen the discovery of the Roentgen Rays born of observation. To the same methods are due the discovery of Hertzian waves, and vibrations of radium, and we await wonderful things from the Marconi telegraph. While there has been no period in which thought has gained so much from positive study as the present century, and this same century promises new light in the field of speculative philosophy and upon spiritual questions, the theories upon the matter have themselves led to most interesting metaphysical concepts. We may say that in preparing the method of observation, we have also prepared the way leading to spiritual discovery.

The education of the senses makes men observers, and not only accomplishes the general work of adaptation to the present epoch of civilisation, but also prepares them directly for practical life. We have had up to the present time, I believe, a most imperfect idea of what is necessary in the practical living of life. We have always started from ideas, and have proceeded thence to motor activities; thus, for example, the method of education has always been to teach intellectually, and then to have the child follow the principles he has been taught. In general, when we are teaching, we talk about the object which interests us, and then we try to lead the scholar, when he has understood, to perform some kind of work with the object itself; but often the scholar who has understood the idea finds great difficulty in the execution of the work which we give him, because we have left out of his education a factor of the utmost importance, namely, the perfecting of the senses. I may, perhaps, illustrate this statement with a few examples. We ask the cook to buy only 'fresh fish.' She understands the idea, and tries to follow it in her marketing, but, if the cook has not been trained to recognise through sight and smell the signs which indicate freshness in the fish, she will not know how to follow the order we have given her.

Such a lack will show itself much more plainly in culinary operations. A cook may be trained in book matters, and may know exactly the recipes and the length of time advised in her cook book; she may be able to perform all the manipulations necessary to give the desired appearance to the dishes, but when it is a question of deciding from the odor of the dish the exact moment of its being properly cooked, or with the eye, or the taste, the time at which she must put in some given condiment, then she will make a mistake if her senses have not been sufficiently prepared.

She can only gain such ability through long practice, and such practice on the part of the cook is nothing else than a belated education of the senses—an education which often can never be properly attained by the adult. Thia is one reason why it is so difficult to find good cooks.

Something of the same kind is true of the physician, the student of medicine who studies theoretically the character of the pulse, and sits down by the bed of the patient with the best will in the world to read the pulse, but, if his fingers do not know how to read the sensations his studies will have been in vain. Before he can become a doctor, he must gain a capacity for discriminating between sense stimuli.

The same may be said for the pulsations of the heart, which the student studies in theory, but which the ear can learn to distinguish only through practice.

We may say the same for all the delicate vibrations and movements, in the reading of which the hand of the physician is too often deficient. The thermometer is the more indispensable to the physician the more his sense of touch is unadapted and untrained in the gathering of the thermic stimuli. It is well understood that the physician may be learned, and most intelligent, without being a good practitioner, and that to make a good practitioner long practice is necessary. In reality, this long practice is nothing else than a tardy, and often inefficient, exercise of the senses. After he has assimilated the brilliant theories, the physician sees himself forced to the unpleasant labor of the semiography, that is to making a record of the symptoms revealed by his observation of and experiments with the patients. He must do this if he is to receive from these theories any practical results.

Here, then, we have the beginner proceeding in a stereotyped way to tests of palpation, percussion, and auscultation, for the purpose of identifying the throbs, the resonance, the tones, the breathings, and the various sounds which alone can enable him to formulate a diagnosis. Hence the deep and unhappy discouragement of so many young physicians, and, above all, the loss of time; for it is often a question of lost years. Then, there is the immorality of allowing a man to follow a profession of so great responsibility, when, as is often the case, he is so unskilled and inaccurate in the taking of symptoms. The whole art of medicine is based upon an education of the senses; the schools, instead, prepare physicians through a study of the classics. All very well and good, but the splendid intellectual development of the physician falls, impotent, before the insufficiency of his senses.

One day, I heard a surgeon giving, to a number of poor mothers, a lesson on the recognition of the first deformities noticeable in little children from the disease of rickets. It was his hope to lead these mothers to bring to him their children who were suffering from this disease, while the disease was yet in the earliest stages, and when medical help might still be efficacious. The mothers understood the idea, but they did not know how to recognise these first signs of deformity, because they were lacking in the sensory education through which they might discriminate between signs deviating only slightly from the normal.

Therefore those lessons were useless. If we think of it for a minute, we will see that almost all the forms of adulteration in food stuffs are rendered possible by the torpor of the senses, which exists in the greater number of people. Fraudulent industry feeds upon the lack of sense education in the masses, as any kind of fraud is based upon the ignorance of the victim. We often see the purchaser throwing himself upon the honesty of the merchant, or putting his faith in the company, or the label upon the box. This is because purchasers are lacking in the capacity of judging directly for themselves. They do not know how to distinguish with their senses the different qualities of various substances. In fact, we may say that in many cases intelligence is rendered useless by lack of practice, and this practice is almost always sense education. Everyone knows in practical life the fundamental necessity of judging with exactness between various stimuli.
