To comprehend the world around us, we first have to decipher how our brains work. This book outlines a new approach to knowledge and understanding based on the elucidation of several basic neuronal mechanisms.This book explores the crucial fact that unconscious processes and conscious experiences form a continuum, which introduces the concept of 'rerepresentations'. Examples of rerepresentations can be seen in language, mathematics, technology and the arts. This fundamental notion captures the essence of being human, namely what separates us from our evolutionary predecessors.For this reason, an effort has been made to present all notions from first principles, without assuming any background specialized knowledge. Although this volume will be more easily accessible to individuals with a background in sciences and medicine, Ways of Comprehending presents, in an accessible manner, important information which should be common knowledge, but is lacking among the vast majority of scientists, technocrats, and humanities scholars.The interdisciplinary, integrative approach presented in this book implies that different disciplines and notions which appear disconnected, are actually closely related. This approach elucidates how we think about topics such as mathematics, physics, painting, music, and philosophy. More importantly, it helps us understand the origin of our thoughts, feelings and actions. This finally brings deep insight and fulfilment or, more precisely, eudemonia.
