By the Court.
Daly, J.The plaintiff was announced to take part in the concert given on the 23d of February, and, unless he was prevented from attending by illness or other sufficient cause, he incurred the forfeiture of a month’s salary. To prevent imposition or feigned illness, the parties agreed that “sickness must be proved by the doctor appointed by the director.” This clause in the contract is somewhat vague, but the meaning undoubtedly is, that the doctor appointed by the director is to determine, in the event of alleged illness, whether the plaintiff is capable of performing or not. The matter is to be left exclusively to him, as an arbitrator between the parties,. and his opinion is to be binding upon both. It was proved by the witnesses, Beneventano and Loder, that Dr. Quin was the physician of the company; that he was appointed by the director, and that notice to that effect was publicly posted up in the opera house. The plaintiff, therefore, is to be presumed to have had knowledge of the fact, and it was his duty, upon being taken sick, to have sent for Dr. Quin, or, at least, to have' *4notified the manager of his illness before the time of performance, unless he was so circumstanced that it was impossible for him to do so..
Indeed, we think that it was incumbent upon him to notify the manager before one o’clock of the day of performance. He had bound himself to conform strictly to each and all of the regulations of the opera company “ commonly in use and it appears, that for the purpose of enabling the manager to prevent the disappointment of the public, by changing the performance or procuring a substitute, a regulation existed, requiring a performer, in the event of possible failure, to give notice to the manager by one o’clock on the day of performance. It was not in writing, but Beneventano proved that it had been adopted from the Theatre La Scala, at Milan, and was a general regulation in opera houses, and perfectly well known to all artists and managers. It is fair to presume, that the plaintiff, as a member of the company, had knowledge of its existence; and as the regulation was one essential to the proper conduct and management of such an establishment, it was his duty to have notified the manager before one o’clock, unless his illness occurred after that period.
The fact of the plaintiff’s non-attendance at the concert in question having been proved, it rested with him to show, by Dr. Quin, that he was incapable of attending from sickness. He was either required to do this, or prove that he had in due time notified the doctor, or the manager, of his illness. He offered no such testimony; but having shown that Dr. Quin practiced upon principles of homeopathy, he insisted that he was not a doctor, and that the defendant having failed to appoint a doctor, he was at liberty to show, by general testimony, that he was ill upon the night in question. In this view of the law the justice concurred; and the plaintiff called Dr. Kissam, who testified that he attended the plaintiff for a disease of the throat in the month of February; that he could not state the exact time, or whether he had attended him on the 23d of February, but that it was his impression that the plaintiff was ill at the time of the con*5cert, because he did not comply with four or five engagements at the witness’ house about that time; and having also called another witness, who testified that he saw the plaintiff on the 23d of February, between the parts of the concert, and that he was in bed and ill, the justice gave judgment for the whole amount claimed.
In the opinion delivered by the justice, he says: “ Though it was proved that Dr. Quin was appointed by the director, yet it has not been proved that Quin was a doctor*, that he had taken a degree as doctor of medicine, or that he was authorized by the medical society, or that he had a regular license to practice, which, I think, was necessary to constitute him a doctor. As far as there was evidence on that subject, it went to show that Dr. Quin practiced upon principles of homeopathy, and such practitioners are not recognized by the faculty of medicine, nor by a majority of the public, as regular practitioners.” In this, we think, the justice erred.
By the terms of the contract, the selection of the doctor vas left entirely to the defendant, and it was for him to judge )f the fitness or capacity of the person to be selected. All that he was required to do, in the fair interpretation of the contract, was to appoint a person who made it his business to practice physic, and it was wholly immaterial to what school of medicine the person so selected belonged, or whether he belonged to any. The legal signification of the term doctor, when employed as it is in this contract, means, simply, a practitioner of physic. The system pursued by the practitioner is immaterial. The law has nothing to do with the merits of particular systems. Their relative merit may become the subject of inquiry when the skill or ability of a practitioner, in any given case, is to be passed upon as a matter of fact. But the law does not, and cannot supply any positive rules for the interpretation of medical science. It is not one of those certain or exact sciences in which truths become established and fixed, but is essentially progressive in its nature, enlarging with the growth of human experience, and subject to those changes and revolutions inci*6dent to any branch of human inquiry, the laws of which are not fully ascertained. The labors of the anatomist, the physi ologist and the chemist have contributed an immense storehouse of facts; but the manner in which this knowledge is to be applied in the treatment and cure of diseases has been, and will probably continue to be, open to diversity of opinion. No one system of practice has been uniformly followed, but physicians, from the days of Hippocrates, have been divided into opposing sects and schools. The sects of the dogmatists and the empirics divided the ancient world for centuries, until the rise of the methodics, who, in their turn, gave way to innumerable sects. Theories of practice, believed to be infallible in one age, have been utterly rejected in another. For thirteen centuries Europe yielded to the authority of Galen. He was implicitly followed—his practice strictly pursued. Every thing that seemed to conflict with his precepts was rejected; and yet, in the revolutions of medical opinion, the works of this undoubtedly great man were publicly burned by Paracelsus and his disciples; and for centuries following, the medical world was divided between the Galenists and the chemists, until a complete ascendancy over both was obtained by the sect of the vitalists. This state of things has been occasioned by the circumstance that medical practitioners have often been more given to the formation of theories upon the nature of disease and the mode of its treatment than to that careful observation and patient accumulation of facts, by which, in other sciences, the phenomena of nature has been unraveled. I am far from undervaluing the great benefits conferred upon mankind by the study of medicine, and have no wish to minister to any vulgar prejudice against a useful and learned profession, but it is not to be overlooked that, as an art, it has been characterized, in a greater degree, by fluctuations of opinion as to its principles and the mode of its practice, than, perhaps, any other pursuit. That it has been distinguished by the constant promulgation and explosion of theories. That it has alternated between the advancement of new doctrines and the revival of old *7ones, and that its professors in every age have been noted for the tenacity with which they have clung to opinions, and the unanimity with which they have resisted the introduction of valuable discoveries. They still continue to disagree in respect to the treatment of diseases as old as the human race; and, at the present day, when great advances have been made in all departments of knowledge, a radical and fundamental difference divides the aTlopathists from the followers of Hanneman, to say nothing of those who believe in the sovereign instrumentality of water.
In fact, nothing comparatively is known of the philosophy of disease. Its eradication or cure, where the result of human agency is, in the great majority of instances, attributable rather to the careful observation, judgment and experience of the particular practitioner, than the application of general or established methods available by all. The popular axiom,' that “ doctors differ,” is as true now as it ever was, and as long . as it continues to be so, it is impossible for the law to recognize any class of practitioners, or the followers of any particular system or method of treatment, as exclusively entitled to be regarded as doctors. In adverting to the conflicting views and differences of opinion that exist and have ever existed in the practice of the healing art, it is not to call in question the value of learned, skillful and experienced physicians, but merely to show the error of attempting, in the present state of medical science, to recognize, as matter of law, any one system of practice, or of declaring that the practitioner who follows a particular system is a doctor, and that one who pursues a different method is not. (a)
*8The error of the court below consisted in undertaking to do this; in holding that the person appointed by the director was not a doctor, because he practiced upon principles of homeopathy, and in Assuming, judicially, that a license from some institution or body, or a degree conferred by some medical college, or the authority of some medical society, was necessary before a man could be .considered in the law a practitioner of physic.
The qualifications of physicians have occasionally been made a matter of statute regulation. To secure a certain amount of preparatory knowledge, laws have been passed requiring an attendance upon medical lectures, an examination before a medical board and a certificate from organized medical bodies, before an individual was authorized to practice, or at least before he could maintain an action to recover for his services. Such laws formerly existed in this state, but the legislature, whether wisely or not, thought fit to repeal them by the act of 1844. (Laws of 1844, p. 406.) And since the passage of that act, any person may practice physic in this state, and maintain an action for his services, subject to being punished for a misdemeanor if convicted of gross ignorance, malpractice or immoral conduct, and with a liability to an action for damages in the event of malpractice. If the plaintiff desired a particular kind of physician, he should have stipulated for him; but having left the selection entirely to the director, the director had a right to appoint a homeopathic physician, or to appoint any individual who made it Ms regular business to practice physic.
Judgment reversed.
It may, perhaps, he safely questioned, whether the sister sciences of law and theology present any such unity or certainty of opinion as might enable them to arraign the medical profession; and whether the course of human investigation, upon any field of inquiry, is not equally marked by a tenacious adherence to old landmarks and a gradual adoption of new theories of progress. The opposition encountered by Harvey’s discovery of the circulation of the blood, finds its, counterpart in every stage of natural science, since the persecutions which inaugurated the Copernican system of the universe.— Ref.
