So I came up with this thought experiment about a month ago. I believe it was Okham, in the medieval era of philosophy, who said that there are two kinds of existence: in the mind and in reality. He proposed that one cannot use solely a concept in the mind to prove its existence in reality. He called the things which exist only in the mind "thought objects". So, think of a thought object, that is, something imaginary like a unicorn. Is it not based entirely upon reality? A unicorn is a horse with white hair and a horn. A hippogriff is some sort of horse-eagle. Numbers represent real quantities in nature, that is, there is such a thing as singularity and plurality has many forms, 3, 4, 5, etc. So it seems that our imagination is limited to our relation with the real world, our memories and experiences and senses, which is what Hobbes and Hume argued. But what about infinity. On what reality is that based on. And by infinity, I do not speak of 0/0 or that sideways 8 used in math class. I'm talking about "that than which nothing greater can be thought", which is necessarily greater than "that than which nothing greater can be thought". The thing that contains all things, but is, through its own definition, infinitely larger than the sum of all things. Surely, if infinity were a "thought object" and did not actually exist, it should be based on some sort of reality just as a hippogriff or a purple cow is. So how is infinity expressed, other than itself? One might say that one thinks of it simply by observing passing time and imagining the time going on forever... but this concept of foreverness uses the concept of infinity. One might say that one observes the nature of summations, how larger quantities are composed of the sum of smaller quantities, so infinity could be the sum of the number 1 added to itself many times forever AWW CRAP that uses the concept of infinity as well. So where does this concept come from? Did our teachers teach it to us? What was their definition? On what reality did they express their definition other than infinity itself in order to show us what infinity is? It is my contention that humans are born with the concept of infinity already implanted in their brain, which is the only reason why we appear to be so much more advanced than animals. But the questions still remain: How do we know what infinity is? Where did this concept come from? I think there are two possible answers: 1. All humans create this great concept out of absolute nothingness. But if this is so, how does a finite thing create, out of nothing, the thought of infinity. 2. Infinity does exist in reality, which is how we know what it is. But this infinity is not bound to time, it exists in and of itself by its own definition. If it were limited to anything other than itself then it would not be itself. Therefore this infinity is omnipotent, omnipresent, omniscient, and is a person. You can see what I'm doing here. Who disagrees with my argument? Please, refute it.
