Index. Footnotes To The Students Past And Present Of Maynooth College PREFACE. It is hoped that the present volume will supply a want that is really felt by students of philosophy in our universities—the want of an English text-book on General Metaphysics from the Scholastic standpoint. It is the author’s intention to supplement his _Science of Logic_(1) and the present treatise on Ontology, by a volume on the Theory of Knowledge. Hence no disquisitions on the latter subject will be found in these pages: the Moderate Realism of Aristotle and the Schoolmen is assumed throughout.
