Abstract
Wittgenstein famously said that in the end we follow rules blindly. Some philosophers interpret Wittgenstein's thoughts about rules as containing the idea of tacit rules.
The article tries to analyze what a tacit rule can and can not be. It is suggested that tacit rules are created by the philosophers in a process of logical construction, rather than observed.
Then a critique of tacit rules, inspired by the work of Nigel Pleasants, is offered. The main points of the critique derive from the absence of rule-related practices that could be connected with tacit rules.
