In the third defence (Die dritte Defension wegen des Schreibens der neuen Rezepte), Paracelsus wrote his now much quoted text: “Was ist das nit gifft ist? alle ding sind gift und nichts ohn gifft. Allein die dosis macht das ein ding kein gifft ist.” In English: “What is there that is not a poison? Every thing [sic] is a poison and nothing is not a poison. Only the dose determines that a thing is not a poison.” A Latin translation appeared in the margin of the 1564 edition (below).
