d unperceived, slips in the foot of her
authority, but having by this gentle and humble beginning, with the
benefit of time, fixed and established it, she then unmasks a furious and
tyrannic countenance, against which we have no more the courage or the
power so much as to lift up our eyes. We see her, at every turn, forcing
and violating the rules of nature:

"Usus efficacissimus rerum omnium magister."

["Custom is the best master of all things."
--Pliny, Nat. Hist.,xxvi. 2.]

I refer to her Plato's cave in his Republic, and the physicians, who so
often submit the reasons of their art to her authority; as the story of
that king, who by custom brought his stomach to that pass, as to live by
poison, and the maid that Albertus reports to have lived upon spiders.
In that new world of the Indies, there were found great nations, and in
very differing climates, who were of the same diet, made provision of
them, and fed them for their tables; as also, they did grasshoppers,
mice, lizards, and bats; and in a time of scarcity of such delicacies, a
toad was sold for six crowns, all which they cook, and dish up with
several sauces. There were also others found, to whom our diet, and the
flesh we eat, were venomous and mortal:

"Consuetudinis magna vis est: pernoctant venatores in nive:
in montibus uri se patiuntur: pugiles, caestibus contusi,
ne ingemiscunt quidem."

["The power of custom is very great: huntsmen will lie out all
night in the snow, or suffer themselves to be burned up by the sun
on the mountains; boxers, hurt by the caestus, never utter a
groan."--Cicero, Tusc., ii. 17]

These strange examples will not appear so strange if we consider what we
have ordinary experience of, how much custom stupefies our senses. We
need not go to what is reported of the people about the cataracts of the
Nile; and what philosophers believe of the music of the spheres, that the
bodies of those circles being solid and smooth, and coming to touch and
rub upon one another, cannot fail of creating a marvellous harmony, the
changes and cadences of which cause the revolutions and dances of the
stars; but that the hearing sense of all creatures here below, being
universally, like that of the Egyptians, deafened, and stupefied with the
continual noise, cannot, how great soever, perceive it--[This passage is
