WHAT IS A THING? WHAT IS THE NATURE OF REALITY? There are only 26 letters in the alphabet. But with those 26 letters over one million English language words can be formed. There are only 88 notes on a common keyboard. Place those notes at the disposal of trained musicians and their instruments, and Bono or Beethoven will send the soul soaring. The numbers 0 to 9 are whole numbers. That's all there are - 10 digits. Yet his handful of digits enables numeration to go on into infinity. Science students are intimately acquainted with the Table of Elements. Two parts hydrogen and one part oxygen form water. Without it life ceases. Fundamentals are indispensable to acquiring knowledge. They are the steel beams within which the entire paradigm of knowledge is constructed. So everyone knows their ABC's, their Do, Re, Mi's and their 1-2-3's. But did you know that hardly anyone can summarize, in order, the sixteen different ways all things (entities) on earth exist? "What constitutes the unity and diversity of reality?" In your hands you hold a clear explanation of the 16 different ways in which all things function. Willem Ouweneel, who holds PhD degrees in biology, philosophy, and theology, brilliantly takes the reader, step by step, through what are called the "16 modalities". Willem wrote this book on the assumption that most readers are unfamiliar with what constitutes the divinely structured unity and diversity of reality. After reading this book, you will have a better understanding and appreciation of creation and the ingenuity of your Creator! In the process you will also find the answer to the riddle that has escaped philosophers since the days of Plato and Aristotle.
