A rational donkey would starve to death between two totally identical piles of hay [Buridan, by PG]

Without magnitude a thing would retain its parts, but they would have no location [Buridan]
9. Objects / D. Essence of Objects / 2. Types of Essence

9. Objects / D. Essence of Objects / 4. Essence as Definition
An Aristotelian essence is a nonlinguistic correlate of the definition [Witt]

A thing is (less properly) the same over time if each part is succeeded by another [Buridan]

Narrow evidentialism relies wholly on propositions; the wider form includes other items [McGrew]
14. Science / A. Basis of Science / 2. Demonstration
Induction is not demonstration, because not all of the instances can be observed [Buridan]
14. Science / A. Basis of Science / 6. Falsification
Falsificationism would be naive if even a slight discrepancy in evidence killed a theory [McGrew]
