Argument for Naturalism from Oneness
Void: Absolute nothing, or nonexistence. Void does not have any properties what so ever. Void does not have any potentialities either. Void is not the same as space, or quantum vacuum, as they have properties, potentialities.
Exist: The very basic property of being. Things can exist as an entity or as a property of another entity. Exist is the opposite of not being, that is void.
Existence: Everything that exists, as oppose to nonexistence/void. The set of all entities/things.
Physical: Under physical I mean something which is generally accepted to be physical, like tables and chairs and the body of human beings. Physical things are entities which are subject to the scientific discipline of Physics. Examples of physical things are, but not limited to, things which are made from the elementary subatomic particles and the four known forces, (The Electromagnetic, the Weak and Strong nuclear forces and Gravity.)
The formal Argument :
1.) If void does not exist, then everything which exist is connected and therefore one single entity.
2.) Void does not exist. (axiom)
3.) Therefore: Everything that exists is fundamentally one single entity .
4.) From 3. Monism is true and dualism or pluralism does not obtain.
5.) From 4. and since part of Existence is physical, the whole Existence is physical.
Conclusion: Everything that exists is physical.
1.) There cannot be no connection between entities, as there is no void to separate them. One could say, that you could separate entity A from entity B by inserting entity C in between them. But, that would mean, that entity A is connected to entity C and entity C is connected to entity B. So, entities A and B still would be connected through entity C.
We can still talk about tables and chairs, at the macro level. As we put limits in the whole Existence, to distinguish parts of it. Any limits, borders we put between entities are purely arbitrary. We can talk about tables and chairs, on macro level. But, when it comes to the subatomic level, we cannot distinguish where the table ends and the air around it begins. As both of them made up of the same subatomic particles. The same can be said for the chair. As we can see the table and the chair are connected through the air. This goes for everything else. Therefore, at the fundamental level of existence, everything is connected and therefore one single thing.
2.) This premise is an axiomatic statement. The word Void here denotes absolute emptiness. It is not quantum vacuum or space, as they have properties. Void does not have any properties. Void is the same as nonexistence, in the metaphysical sense. It is self evident that void, that is truly nonexistence, does not exists. It would be a contradiction, a nonsense, to say that nonexistence exist.
3.) Since void does not exists, everything is connected, united. Therefore, at the fundamental level of existence, every things are parts of One entity.
We may, and we do put arbitrary limits in this one entity, to make sense of Existence. But, at the fundamental level, there are no such limits.
4.) Monism is a metaphysical position that Existence at its basic level is made of one type of substance. In order for entities be connected, they have to have at least one property in common. Since Existence is one entity, all parts of it are connected. That is, all entities in it, at least, share one common property, at the very basic level. Therefore: Monism is true.
We can put this into a syllogism:
4.1.) If all things have at least one common property, then Monism is true.
4.2.) All things have a common property (, because they are connected).
4.3.) Therefore, Monism is true.
As support of this argument. We can break down 4.2 to another syllogism:
4.2.1.) If all things are connected, then they share at least one common property.
4.2.2.) All things are connected.
4.2.3.) Therefore, all things have a common property.
Monism is the direct opposition to Dualism and Pluralism. Therefore, if monism is true dualism and pluralism cannot obtain.
5.) It is self evident that physical entities exist. Since these entities are nothing but arbitrary defined parts of Existence , the whole Existence is Physical. If you know that the floor-covering in a room is made of the same type of material. Even if you cannot see the whole floor. You can conclude, that the floor is made of wood. If you can see, that part of it is made of wood. The same way, as we classify part of Existence physical, therefore the whole Existence has to be physical.
Put this into a syllogism:
5.1.) If part of Existence is physical and Existence is one kind. Then, the whole Existence is physical.
5.2.) Part of the Existence is physical.
5.3.) Therefore, the whole Existence is physical.
Conclusion: Since everything is physical, a non physical God cannot exist. So, even if God exist, it has to be physical. This leaves room for anthropomorphic gods, like the Sun, Moon and human beings declared as gods. But, not for a supernatural “real” God.
