Hi Bruno Marchal What is always either true or false cannot have been invented, only discovered. Necessary or rational truths are such. Contingent truths are not. Rational or necessary truths are therefore a prioi and can only be discovered. Contingent truths or facts are therefore a posteriori and can only be invented. I suppose that knowing which type is at hand is the crucial problem.

Certainly we can agree that we have a common concept of numbers but they are not concrete entities that we can locate in our space and time and do not have any other properties such as mass, charge, spin, duration. Therefore we have to not use the same terminology and common sense with numbers as we do with ordinary objects of the world. One of my motivations as a student of philosophy, is to explore multiple ways to bring the common sense in alignment with the requirements of abstractions, like numbers and to look forward from this alignment to see what might be indicated or predicted.

On 9/6/2012 11:09 AM, Brian Tenneson wrote: Correct me if I'm wrong but my understanding is that sets and membership cannot be defined in terms of a more primary mathematical concept. Functions can be defined in terms of this primitive called sets. Numbers are sets; natural numbers are defined directly in terms of sets (via the Von Neumann approach) and every more complicated number set can be defined in terms of the previous type of number set all the way up to real numbers, complex numbers, and nonstandard number sets. The only type of number I am not sure how they can be seen as sets is that of surreal numbers described by Conway I believe. I don't know much about surreal numbers. Yes, this approach necessitates the existence of sets and membership. Hi Brian, Surreals and hyperreals and non-standard numbers and so on, the list is long! My point is that there really is no such thing as an absolutely irreducible entity. There probably are other ways to define numbers but all properties that we want numbers to have can come from how they are defined in terms of sets. In other words, the set theoretical description of various number sets is sufficient. Depending on what intends to try to explain, but sure. Kronecker said God made the integers; all else is the work of man. I would amend that to say God made sets (and membership); all else is the work of man. Balderdash! We can use the God concept as a way to capture the sum of what exists and its evolution and so forth, but it is just another word that may not refer to anything that really exists.

So you could feel different, or feel nothing, but maintain the delusional belief that nothing had changed. That's begging the question. You are assuming that the brain is a machine which produces consciousness. I think that the brain is the three dimensional shadow of many levels of experience and it produces nothing but neurochemistry and alterations in our ability to access an individual set of human experiences. The brain does not produce consciousness, it defines the form of many conscious relations. But you believe that the neurochemicals do things contrary to what chemists would predict, for example an ion channel opening or closing without any cause such as a change in transmembrane potential or ligand concentration. We've talked about this before and it just isn't consistent with any scientific evidence. You interpret the existence spontaneous neural activity as meaning that something magical like this happens, but it doesn't mean that at all. -- Stathis Papaioannou -- Onward!
