Wincenty Lutosławski (1863–1954) was a multilingual Polish philosopher and author who coined the term 'stylometry'. Originally published in 1930, this book presents the outline of a course in metaphysics delivered by Lutosławski at a variety of academic institutions from 1890 onwards. Numerous aspects of reality are discussed in an effort to form a unified conception of it, from the material world through to abstract spirituality. This book will be of value to anyone with an interest in metaphysics and the development of philosophy.
