A rational donkey would starve to death between two totally identical piles of hay [Buridan, by PG]
     Full Idea: A rational donkey faced with two totally identical piles of hay would be unable to decide which one to eat first, and would therefore starve to death
     From: report of Jean Buridan (talk [1338]) by PG - Db (ideas)
     A reaction: also De Caelo 295b32 (Idea 19740).
2. Reason / F. Fallacies / 8. Category Mistake / a. Category mistakes
We can't do philosophy without knowledge of types and categories [Ryle]
     Full Idea: We are in the dark about the nature of philosophical problems and methods if we are in the dark about types and categories.
     From: Gilbert Ryle (Categories [1938], p.189), quoted by Ofra Magidor - Category Mistakes 1.2
     A reaction: Magidor and others take this to be an assertion about language and logic, but I take it to be an assertion about reality. It is an early assertion of Schaffer's claim that ontology concerns the structure of existence, and not just what exists.
