Not entirely true unless the 'external reality' cannot be descibed
mathematically.
However, it is a reasonable assumption to make that mathematics and logic
apply in all spheres. Hence we could certainly model a variety of external
realities to a degree even if we did not know what it was specifically. Of
course, one might suppose that an external reality that could only be
modelled using uncomputable numbers might screw up that option a bit...
