Philippus Aureolus Paracelsus

“Man is a microcosm, or a little world, because he is an extract from all the stars and planets of the whole firmament, from the earth and the elements; and so he is their quintessence.”

“The dose makes the poison.”

“All things are poison, and nothing is without poison; the dosage alone makes it so a thing is not a poison.”

“The art of healing comes from nature, not from the physician.”

“Medicine is not only a science; it is also an art. It does not consist of compounding pills and plasters; it deals with the very processes of life, which must be understood before they may be guided.”

“He who is born in imagination discovers the latent forces of nature.”

“The physician is only the servant of nature, not her master. Therefore, it behooves medicine to follow the will of nature.”

“Thoughts are free and are subject to no rule.”

“Every physician must be rich in knowledge, and not only of that which is written in books; his own experience is his master.”

“He who knows nothing, loves nothing. He who can do nothing understands nothing. He who understands nothing is worthless.”

“What is looked upon as a religion today may be science tomorrow.”

“Poison is in everything, and no thing is without poison. The dosage makes it either a poison or a remedy.”

“Theory and practice should be together. The physician who has the theory but not the practice is like a tree that bears no fruit.”

“Dreams are not without meaning. They are the messengers of the soul.”

“Magic has the power to experience and fathom things which are inaccessible to human reason. For magic is a great secret wisdom, just as reason is a great public folly.”
