That's the point of my virtuous > circle. To make this into a theory, you need to explain where that virtuous circle comes from. With mechanism, you have the mathematical tools to address the “circle” (recursive definition). Probably not its “virtuous” nature. To say that nothing is primitive will not work: you will need the axioms to get the things making the circle into a reality. Then with mechanism, you can choose any presentation of the sigma_1 arithmetical reality, be it the elementary axioms of arithmetic, or the combinators. > >> >> We believe that he principle X is fundamental or primitive if we believe >> that it cannot be recovered from other principle. >> >> Physicalism assumes that some physical principle have to be assumed to get a >> physical reality, like vitalism assumed that some aspect of life cannot be >> recovered, even in principle, by another science like chemistry or physics. > > No. Physical things don't have to be assumed, they are defined ostensively. A definition by ostension, requires the faith that there is a reality, that we are not dreaming or in an arithmetical video game, or an infinity of them. > It is only the theorizing that hypothesizes principles. But you need an act of faith to believe that there isa reality behind your hypothesises principles. You don’t need faith the formally deduce in a theory, but you need a faith in a reality to confront the theory with possible facts. > >> >> I guess you agree that vitalism is abandoned, and that most scientist accept >> that biology can be reduced to quantum mechanics, even if only in principle. >> >> With mechanism, the same occurs for the physical reality.
