(The logics of topoi are Boolean logics). > SS: Your objection seems to me to imply a fatal disjunction between our usual logics -- the basis of science -- and the actual (changing) world. For example, in biological ontogeny we begin at one scale, and GRADUALLy assemble a larger scale. During this transition the system is ambiguous as to scale. It is CHANGE which faults our thinking here, not the idea that a developing embryo can be modeled as existing at more than one scale. I suppose you can then tell us that your system of logic (LIR) takes care of this, by encompassing change as it happens. Yes?
