Abstract
While the space in which we live operates via a number of physical and mathematical principles, this paper examines a mechanism that lies beyond these principles, called the Principle of Ideas. This mechanism is analyzed here as being the source of universe creation, and which can influence not only human history but also individual lifetimes. Building on work by thinkers such as Nozick, Penrose, and Aristotle, the Principle of Ideas consists of three sub-principles, called the 1st, 2nd, and 3rd Universal Principles, which can be pooled to create the concept of maximal existence. In addition to guaranteeing the existence of the universe, maximal existence also influences the form of universe. Using the concept of maximal existence, we can also explain why the physical constant of the universe is precisely adjusted toward the birth of human existence and how the enantiomeric universe as a multiverse can exist.
