It is commonly believed that the nature of God cannot be discussed scientifically, because science applies only to matter. This book challenges this assumption and defines God as perfection and discusses 12 qualities that constitute perfection. These qualities can be applied to anything, but in this book, they are applied to the idea of the perfection of knowledge. What is perfection in knowledge? That knowledge which is consistent, complete, simple, parsimonious, necessary, sufficient, empirical, operational, instrumental, stable, and novel, is perfect. These 12 qualities are organized in six pairs in the Vedic philosophical description of God, and called knowledge, beauty, renunciation, power, wealth, and heroism. By discussing the nature of perfection, identifying how this world also carries such perfection partially (but never completely), we can understand how God is complete perfection.
