On the Dator Formarum

Introduction by Dimitri Gutas

Avicenna says: "And each of these elements has latitude in its quality; it can be more and less, since its natural or accidental quality may have been intensified or weakened, while retaining its form and species. Nevertheless, this intensification and weakening has terminating limits. Once those limits are transcended the complete disposition in matter for that form is lost and a complete disposition for another form disposes [that matter]."
