In its most broad sense, the word “world” denotes the totality of human societies, to all aspects of reality or to all that exists. However, the nature of this world is typically conceptualized in different ways in different disciplines. Some conceptions view the world as being absolutely unique while some speak of a ” plurality of worlds ” simultaneously existing in parallel. For purposes of discussion, “the world “is used in contexts where the context refers to all aspects of reality.
Some philosophers argue that the world is nothing more than the ensemble of definite and distinct physical things. On this view, we find ourselves in a world where objects have definite properties and each of these physical things has a different place in spacetime. Philosophers who subscribe to this view assume that our existence is governed by the laws of classical mechanics. They further assume that two different worlds, even slightly similar in structure, are ruled by completely different laws.
A variety of alternative views exist. For example, some philosophers believe that the world consists of possible worlds or virtual worlds. These virtual worlds might be the only world that exists in relation to ours. By the same token, the physical world is a different world from all the possible worlds, and it is the only world that we can experience directly. This means that, contrary to some common assumptions, we are not in a plurality of possible worlds.
Another possibility is that there are no absolute reference frames. Rather, all reference frames refer to different planes of reference on the physical plane. A reference frame is a set of possible worlds with reference to which every other possible world coincides. The other assumption concerning the nature of the actual world is that it exists in a vacuum, outside of all possible worlds. Although there are many possible worlds that could exist in the vacuum, only the one that we inhabit actually does.
There are also other theories regarding the nature of the actual world. One popular thesis regards the world as consisting of multiple totalities, sometimes referred to as parallel totalities. Another thesis postulates that the actual world contains an infinite number of possible worlds, referred to as infinitesimals. Finally, a few philosophers think that it is impossible to know anything definite, including the total reality, since there is no way things could have made themselves equal.
Although there are many different theories in the search for the actual world, only one of them makes sense: The world is made up of inner-worldly things. From the fundamental principles of physics, to the deepest workings of our brains, everything has its root in an interior world, and there are countless such inner-worldly things, each of them unique. To know the actual world, we must go inside of it.
