Pseudodoxia Epidemica

Pseudodoxia Epidemica or Enquries into very many received tenets and commonly presumed truths, also known simply as Pseudodoxia Epidemica or Vulgar Errors, is a work by Thomas Browne refuting the common errors and superstitions of his age. It first appeared in 1646 and went through five subsequent editions, the last revision occurring in 1672. The work includes evidence of Browne's adherence to the Baconian method of empirical observation of nature, and was in the vanguard of work-in-progress scientific journalism in the 17th century scientific revolution, though he refers to his work as an encyclopaedia. Throughout its pages frequent examples of Browne's subtle humour can also be found.

Browne's three determinants for obtaining truth were firstly, the authority of past authors, secondly, the act of reason and lastly, empirical experience. Each of these determinants are employed upon subjects ranging from the cosmological to common folklore. Subjects covered in Pseudodoxia are arranged in the time-honoured Renaissance scale of creation, the learned doctor assaying to dispel errors and fallacies concerning the mineral, vegetable and animal kingdoms before moving to errors pictorial, to those of man, geography, astronomy and finally of the cosmos.
