Vincenzo Fano provides an illustration of the point that holism of the mental generates anomalism. Fano asks us to first consider the attribution of length to a table. To do this, we must assume a set of laws concerning the interaction between the table and the measuring apparatus: the length of the table doesn't vary significantly during the measurement, length must be an additive quantity, "longer than" must be an asymmetric, transitive relation and so forth. By assuming these laws and carrying out a few operations, we reach the result of the measurement. There is a certain amount of holism in this process. For example, during the measurement process, we might discover that the table is much hotter than the measuring device, in which case the length of the latter will have been modified by the contact. Consequently, we need to modify the temperature of the measuring device. In some cases, we will even have to reconsider and revise some of our laws. This process can continue for some time until we are fairly confident of the results obtained. But it is not only necessary to have a theory of the interactions between the table and the measuring device, it is also necessary to attribute a set of predicates to the table: a certain temperature, rigidity, electric charge, etc... And the attribution of each of these predicates presupposes, in turn, another theory. So, the attribution of "F" to "x" presupposes "Px" and the theory formula_1, but "Px", in turn, presupposes "P'x" and formula_2 and so on. As a result, we have a series of predicates "F", "P", formula_3, formula_4... and a series of theories formula_5, formula_2, formula_7... As Fano states it, "this process would seem like a "regressus ad infinitum", if it weren't that formula_8 converges toward a theory "T" which is nothing other than physics in its entirety." The same is true of the predicates, which converge toward the set of all the possible physical quantities. Fano calls this 'convergent holism'.
