still fly, now and then, at the same quarry. Paracelsus, disfigured as his teaching was by mysticism, the arts of the charlatan, and by his ignorant repudiation of the service of Anatomy, struck the first damaging blows at this illegitimate ascendency, by the frequent success of his empirical treatment, by the contempt he heaped upon the scholastic authorities, and by the boldness with which he assailed every thesis which they maintained. Men of more sober intellect and weighty learning soon followed in his track. Fernelius, one of the physicians Cardan met in Paris, boldly rejected what he could not approve by experience in the writings of Hippocrates and Galen, and stood forth as the advocate for free inquiry, and Joubert of Montpelier, Argentier of Turin, and Botal of Asti subsequently took a similar course.
When Cardan went to study at Pavia in 1519 this tradition was unshaken. It was not until the advent of Vesalius that the doom of the ancient system was sounded. Then, when Anatomy sprang to the front as the potent ally of Medicine, the science of healing entered upon a fresh stage, but this new force did not make itself felt soon enough to seduce Cardan from the altars of the ancients to the worship of new gods. As long as he lived he was a follower of the great masters, though at the same time his admiration of the teaching of Vesalius was enthusiastic and profound. His love of truth and sound learning forbade him to give unreflecting adhesion to the precepts of any man, however eminent, and when he found that Galen was a careless commentator on Hippocrates,[264] and failed to elucidate the difficulties with which he professed to deal, he did not spare his censure.[265] In the _De Subtilitate_ he speaks of him as "Verbosus et studio contradicendi taedulus ut alterum vix ferre queas, in reliquo gravis jactura artium posita sit, quam nostrae aetatis viri restituere conati sunt."[266] But as Galen's name is quoted as an authority on almost every page of the _Consilia Medica_, it may be assumed that Cardan's faith in his primary theories was unshaken. In his Commentaries on Hippocrates, Galen professes a profound respect for his master, but the two great men must be regarded as the leaders of rival schools; indeed it could hardly be otherwise, seeing how vast was the mass of knowledge which Galen added to the art during his lifetime.
Hippocrates, by denying the supernatural origin of disease, by his method of diagnosis, by the importance he attached to air and diet, by his discriminating use of drugs, and by the simplicity of his system generally, had placed Medicine on a rational basis. In the six hundred years' space which elapsed before the appearance of Galen, Medicine was broken up into many rival schools. The Dogmatici and the Empirici for many years wrangled undisturbed, but shortly after the Christian era the Methodici entered the field, to be followed later on by the Eclectici and a troop of other sects, whose wranglings, and whose very names, are now forgotten. In his _History of Medicine_, Dr. Bostock gives a sketch of the attitude of Galen towards the rival schools. "In his general principles he may be considered as belonging to the Dogmatic sect, for his method was to reduce all his knowledge, as acquired by the observation of facts, to general theoretical principles. These principles he indeed professed to deduce from experience and observation,[267] and we have abundant proofs of his diligence in collecting experience and his accuracy in making observations; but still, in a certain sense at least, he regards individual facts and the details of experience as of little value, unconnected with the principles which he laid down as the basis of all medical reasoning. In this fundamental point, therefore, the method pursued by Galen appears to have been directly the reverse of that which we now consider as the correct method of scientific investigation; and yet, such is the force of actual genius, that in most instances he attained the ultimate object in view, although by an indirect path. He was an admirer of Hippocrates, and always speaks of him with the most profound respect, professing to act upon his principles, and to do little more than expound his doctrines and support them by new facts and observations. Yet in reality we have few writers whose works, both as to substance and manner, are more different from each other than those of Hippocrates and Galen, the simplicity of the former being strongly contrasted with the abstruseness and refinement of the latter."
The antagonism between these two great men was not perhaps more marked than might have been expected, considering that an interval of six hundred years lay between them. However loyal he may have been to his master, Galen, with his keen, catholic, and subtle intellect, was bound to fall under the sway of Alexandrian influence while he studied in Alexandria as the pupil of Heraclianus. The methods of the contemporary school of philosophy fascinated him; and, in his endeavour to bring Medicine out of the chaotic welter in which he found it, he attempted--unhappily for the future of science--to use the hyper-idealistic Platonism then dominant in Alexandria, rather than the gradual and orderly induction of Hippocrates, as a bond of union between professional and scientific medicine; a false step for which not even his great services to anatomy and physiology can altogether atone. Yet most likely it was this same error, an error which practically led to the enslavement of Medicine till the seventeenth century, which caused Cardan to regard him, and not Hippocrates, as his master. The vastness and catholicity of Galen's scheme of Medicine must have been peculiarly attractive to a man of Cardan's temper; and that Galen attempted to reconcile the incongruous in the teleological system which he devised, would not have been rated as a fault by his Milanese disciple.
Galen taught as a cardinal truth the doctrine of the Hippocratic elements, heat, cold, moisture, and dryness, and a glance at the Consilium which Cardan wrote out on Archbishop Hamilton's illness, will show how completely he was under the sway of this same teaching. The genius of Hippocrates was perhaps too sober and orderly to win his entire sympathy; the encyclopaedic knowledge, the literary grace, and the more daring flights of Galen's intellect attracted him much more strongly. Hippocrates scoffed at charms and amulets, while Galen commended them, and is said to have invented the anodyne necklace which was long known and worn in England. There is no need to specify which of the masters Cardan would swear by in this matter. The choice which Cardan made, albeit it was exactly what might have been anticipated, was in every respect an unfortunate one. He put himself under a master whose teaching could have no other effect than to accentuate the failings of the pupil, whereas had he let his mind come under the more regular discipline of Hippocrates' method, it is almost certain that the mass of his work, now shut in dusty folios which stand undisturbed on the shelves for decade after decade, would have been immeasurably more fruitful of good. With all his industry in collecting, and his care in verifying, his medical work remains a heap of material, and nothing more valuable. Learning and science would have profited much had he put himself under the standard of the Father of Medicine, and still more if fate had sent him into being at some period after the world of letters had learned to realize the capabilities of the inductive system of Philosophy.
It may readily be conceded that Cardan during his career turned to good account the medical knowledge which he had gathered from the best attainable sources, and that he was on the whole the most skilful physician of his age. He likewise foreshadowed the system of deaf mute instruction. A certain Georgius Agricola, a physician of Heidelberg who died in 1485, makes mention of a deaf mute who had learnt to read and write, but this statement was received with incredulity. Cardan, taking a more philosophic view, declared that people thus afflicted might easily be taught to hear by reading, and to speak by writing; writing was associated with speech, and speech with thought, but written characters and ideas might be connected without the intervention of sounds.[268] This view, put forward with all the authority of Cardan's name, would certainly rouse fresh interest in the question, and, whether stimulated by his words or not, an attempt to teach deaf mutes was made by Pedro de Ponce, a Spanish Dominican, about 1560. But it would not be permissible to claim for Cardan any share in the epoch-making discoveries in Medicine. Galen as an experimental physiologist had brought diagnosis to a level unattained before. His methods had been abandoned by his successors, and practice had in consequence suffered deterioration, but Cardan, studying under the revived Galenism, called into life by the teaching of Vesalius, went to deal with his cures under conditions more favourable than those offered by any previous period of the world's history. His cure of Archbishop Hamilton's asthma, over which Cassanate and the other doctors had failed, was due to a more careful diagnosis and a more judicious application of existing rules, rather than to the working of any new discoveries of his own. Viewed as a soldier in the service of Hygeia, how transient and slender is the fame of Cardan compared with that of Linacre, Vesalius, or Harvey! Were his claims to immortality to rest entirely on his contribution to Medicine, his name would have gone down to oblivion along with that of Cavenago, Camutio, Della Croce, and the multitude of jealous rivals who, according to his account, were ever plotting his downfall. But it was rescued from this fate by his excellence as a mathematician, by the interest clinging to his personality, by the enormous range of his learning, by his picturesque reputation as a dreamer of dreams, and a searcher into the secrets of the hidden world. In an age when books were few and ill-composed, his works became widely popular; because, although he dealt with abstruse subjects, he wrote--as even Naude admits--in a passably good style, and handled his subject with a lightness of touch which was then very rare. This was the reason why men went on reading him long after his works had ceased to have any scientific value; which induced writers like Burton and Sir Thomas Browne to embroider their pages freely with quotations from his works, and thus make his name familiar to many who have never handled a single one of his volumes.
It is somewhat strange to find running through the complex web of Cardan's character a well-defined thread of worldly wisdom and common-sense; to find that a man, described by almost every one who has dealt with his character as a credulous simpleton, one with disordered wits, or a down-right madman, should, when occasion demanded, prove himself to be a sharp man of business. When Fazio died he left his son with a number of unsettled law-suits on hand, concerning which he writes: "From my father's death until I was forty-six, that is to say for a space of twenty-three years, I was almost continually involved in law-suits. First with Alessandro Castillione, surnamed Gatico, with respect to certain plantations, and afterwards with his kinsfolk. Next with the Counts of Barbiani, next with the college, next with the heirs of Dominico de Tortis, who had held me in his arms when I was baptized. Out of all these suits I came victorious. It was indeed a matter for surprise that I should have got the better of Alessandro Castillione, seeing that his uncle sat as judge. Moreover, he had already got a decision against me, a decision which, as the jurisconsults declared, helped my case as the
