This contribution is a reaction to Materna’s critique of “anti-realism” and his defence of the objectivity of logical and other rules. It suggests that Materna’s approach, which treats the rules of chess, for example, as objective, is quite unusual. In addition an attempt is made to show that Materna’s position, which holds that the sentence “Czech is not a Finno-Ugric language” does not have to be true, and that it is grounded on a very unusual conception of language, which may ultimately undermine Materna’s thesis about the necessary truth of logical rules.
