I am going to talk about the necessity of the reason to know by talking about the nature of spacetime, and therefore, of our nature. I'm not sure whether this is specific enough for StackExchange, but my question is, is the paragraph below sensible?
Here are my propositions:
- It is not important to know the fake.
- All that exists is the physical (physicalism).
There are two possibilities: either spacetime is real or fake. If it is fake, our "existence" is also fake. It is not important to know anything that is fake. So there is no need to know at all.
Otherwise, spacetime is real. If it is real, then so are we. Since all which exists is the physical, our minds must be a product of the physical. And due to the limit on all physicals, our minds are bounded on what we can store, as well as on what we can understand. Therefore, we can never know everything.
- What if we are our memories are bounded, but our ability to grasp is not?
It is impossible to occur because how will we ever know what we will never know? A contradiction therefore exists.
