This monograph details a new solution to an old problem of metaphysics. It presents an improved
version of Ostrich Nominalism to solve the Problem of Universals. This innovative approach
allows one to resolve the different formulations of the Problem which represents an important
meta-metaphysical achievement.In order to accomplish this ambitious task the author appeals to
the notion and logic of ontological grounding. Instead of defending Quine's original principle
of ontological commitment he proposes the principle of grounded ontological commitment. This
represents an entirely new application of grounding.Some metaphysicians regard Ostrich
Nominalism as a rejection of the problem rather than a proper solution to it. To counter this
the author presents solutions for each of the formulations. These include: the problem of
predication the problem of abstract reference and the One Over Many as well as the Many Over
One and the Similar but Different variants.This book will appeal to anyone interested in
contemporary metaphysics. It will also serve as an ideal resource to scholars working on the
history of philosophy. Many will recognize in the solution insights resembling those of
traditional philosophers especially of the Middle Ages.
