To analyze dynamic strategic interactions of games, Reinhard Selten, a German economist who won the Nobel Prize for Economic Science in 1994 for his analysis of equilibrium in noncooperative game theory, introduced restrictive clauses during what he called “subgame perfection”. He introduced an additional clause called “trembling hand equilibrium” (Equilibrios de la Mano Temblorosa), where each player supposes that there is always a margin of error and so in deciding on any strategy, realizes that “the hand” tends to tremble. Consequently, he modifies his plans generating new circumstances which interrupt the stability of his goal. Such room for error is an opportunity to reacquaint ourselves with our reality by considering the unstable, i.e. the ease of everyday life itself. That need diverts us from utilitarianism towards other, larger undefined spaces, i.e. places where the probable occurs. That is evidence of will and desire, and that will needs to be re-established or redefined if you make a mistake. Committing an error means new feelings, ideas and experiences.
