s who have
the stone (so scornfully they use us in our miseries) the excrement of
rats beaten to powder, and such like trash and fooleries which rather
carry a face of magical enchantment than of any solid science. I omit
the odd number of their pills, the destination of certain days and feasts
of the year, the superstition of gathering their simples at certain
hours, and that so austere and very wise countenance and carriage which
Pliny himself so much derides. But they have, as I said, failed in that
they have not added to this fine beginning the making their meetings and
consultations more religious and secret, where no profane person should
have admission, no more than in the secret ceremonies of AEsculapius; for
by the reason of this it falls out that their irresolution, the weakness
of their arguments, divinations and foundations, the sharpness of their
disputes, full of hatred, jealousy, and self-consideration, coming to be
discovered by every one, a man must be marvellously blind not to see that
he runs a very great hazard in their hands. Who ever saw one physician
approve of another's prescription, without taking something away, or
adding something to it? by which they sufficiently betray their tricks,
and make it manifest to us that they therein more consider their own
reputation, and consequently their profit, than their patient's interest.
He was a much wiser man of their tribe, who of old gave it as a rule,
that only one physician should undertake a sick person; for if he do
nothing to purpose, one single man's default can bring no great scandal
upon the art of medicine; and, on the contrary, the glory will be great
if he happen to have success; whereas, when there are many, they at every
turn bring a disrepute upon their calling, forasmuch as they oftener do
hurt than good. They ought to be satisfied with the perpetual
disagreement which is found in the opinions of the principal masters and
ancient authors of this science, which is only known to men well read,
without discovering to the vulgar the controversies and various judgments
which they still nourish and continue amongst themselves.

Will you have one example of the ancient controversy in physic?
Herophilus lodges the original cause of all diseases in the humours;
Erasistratus, in the blood of the arteries; Asclepiades, in the invisible
atoms of the pores; Alcmaeon, in the exuberance or defect of our bodily
strength; Diocles, in the inequality of
