Medieval nominalism includes, in part, the ideas of (1) Roscelin (a scholastic), (2) Ibn Khaldun (Abd Ar Rahman bin Muhammed ibn Khaldun), and (3) the Via Moderna (Latin, the modern way, i.e., nominalist and terminist) of William of Ockham (also a scholastic) and his successors, such as:

1. Robert Holkot
2. Gregory of Rimini
3. Gabriel Biel ("Gabrielism")
4. Pierre d'Ailly
5. Jean Gerson
6. John Buridan
7. Martin Luther (a Gabrielist but technically modern, not medieval)

Medieval nominalism is here modified according to Dr. Mark A. Foster's views, including his understandings of the teachings of the Bahá'í Faith.
