The Dose Makes the Poison (Paracelsus)

Lyrics

[Verse 1]
Your real name
was Philippus Aureolus Theophrastus Bombastus von Hohenheim
which is four names too many
for a man who spent his life
insisting on simplicity
You renamed yourself Paracelsus —
beyond Celsus —
beyond the Roman authority
the medical schools
were still quoting
a thousand years after
the Roman had stopped
being right about anything
You burned Avicenna's Canon
in a bonfire outside the university
at Basel
in front of the students
who had come to watch you teach
and what you taught them
was that the fire
was the first lecture

[Verse 2]
The dose makes the poison —
that was yours,
the sentence that invented toxicology
in six words:
everything is toxic,
nothing is toxic,
only the amount decides
which face the substance wears
Water will kill you
in sufficient volume
and arsenic will cure you
at the right grain
and the space between medicine and murder
is a number
that smells like apothecary dust
and tastes like the particular copper
of a coin held too long
in a sweating hand

[Chorus]
You wandered Europe
for twenty years
with a sword on your hip
and a medicine bag
on the other
treating miners, peasants,
anyone the university doctors
refused to see
because they charged
what miners could not pay
and diagnosed
in a Latin
the miners could not read
You prescribed opium
and mercury
and antimony
and zinc
and you tested everything
on yourself first
because the body
you could afford to lose
was the one you carried
and you carried it hard
through taverns and clinics
and mountain passes
and the specific filth
of a man who trusts
experience over citation

[Verse 3]
They threw you out of Basel
after two years
because you lectured in German
instead of Latin
and treated barbers
as colleagues
and told the faculty
their degrees
were less useful
than a week
spent watching a wound heal
The Broca's area
that switched from Latin to German
was not making a linguistic choice —
it was making a political one:
the language the patient speaks
is the language the medicine
should arrive in
and the doctors
who refused to translate
were not protecting knowledge —
they were hoarding it

[Bridge]
You believed in the tria prima —
salt, sulfur, mercury —
the three substances
from which all matter derives
You were wrong
the way Kircher was wrong:
productively,
at a scale that moved the field
closer to the answer
by being a better shape of incorrect
The alchemists
who came after you
carried your errors
like seeds
that grew into chemistry
once the soil
stopped believing in gold

[Outro]
You died at forty-seven
in a tavern in Salzburg
of something
nobody could diagnose —
mercury poisoning, probably,
from the treatments
you tested on yourself
which means the dose
made you the poison
and the lesson
outlived the teacher
by five hundred years
and the bonfire
is still burning
in every clinic
where someone says
show me the evidence
instead of
show me the authority
