  The aim of the paper is to examine the notion of simple Kantian equilibrium
in $2 \times 2$ symmetric games and their quantum counterparts. We focus on
finding the Kantian equilibrium strategies in the general form of the games. As
a result, we derive a formula that determines the reasonable strategies for any
payoffs in the bimatrix game. This allowed us to compare the payoff results for
classical and quantum way of playing the game. We showed that a very large part
of $2\times 2$ symmetric games have more beneficial Kantian equilibria when
they are played with the use of quantum strategies.
