Dici de omni

A new article in the Logic Museum on the dici de omni, a principle derived from Aristotle which was supposed by the medieval scholastic writers (such as Giles of Rome) to underlie all reasoning.  The article mentions the debased and inaccurate  version of the principle used by neo-scholastic writers and used in manuals of 'traditional logic' such as Mill's System of Logic.  It also mentions the current version of the Wikipedia article, which is seriously incomplete and inaccurate.  The irony, which I love, is that Wikipedia will be unable to link to the more comprehensive Logic Museum article because of the ban on all outward-bound links to the Logic Museum.  There is also a new category for 'dici de omni' so you can reference scholastic texts mentioning the principle, as well as a category for Wikipedia articles, linked from the Logic Museum, which need improvement.
