Mert 1) igaza Poincarenak, hogy a terrol es idorol tett kijelenteseink nem a valosag tenyeit fejezik ki, hanem konvencionalisak, 2) mert a Lorentz-elmelet egy letezo, kezenfekvo alternativaja a relativitaselmeletnek, mikozben a terrol es az idorol egeszen mast mond, 3) mert a relativitaselmelet olyasmit nevez ternek es idonek, amit jozan esszel eszunk agaban sem lenne ternek es idonek nevezni, s csak azert nem kerulunk ellentmondasba a fizikai megfigyelesekkel, mert -- Poincare szellemeben szolva -- teljesen mindegy, hogy mit nevezunk ternek es idonek.

It has however come under frequent attacks on the ground that its demands for human rationality are overly stringent. It responded to these challenges vigorously by the imposition of the construct of evolutionary games. In this talk I suggest to consider, in turn, the structure of its so-called solution (or equilibrium) concepts. These concepts can be assessed independently from the norms of rationality the theory tends to entail. However, as I will argue, none of the equilibrium concepts leave room for truly interdependent choice and thus the theory should be seen as unable to address a large range of issues in the social sciences and in moral philosophy - an embarrassment given its wide-ranging ambitions. I will demonstrate this claim by the example of the Prisoner's Dilemma and will especially consider the extent to which this game can contribute to the discussion of central issues in moral philosophy. In the talk, I will present the relevant solution concepts in their full-fledged mathematical form so that we will be able attend without hindrance to their conceptual structure.

Ez a szereposztas neha felrevezeto: a kezdeti feltetelek kozotti valogatas fontos reszeve valhat a torvenyeknek. Ennek legfontosabb peldaja az irreverzibilitas, ahol a mikroszkopikus reszletekre - a kontextusra - vonatkozo kezdofeltetelek valogatasa vezet a makroszkopikus dinamika melyrehato modosulasahoz. A kezdeti feltetelektol kulonbozo, de nemikeppen analog, a torveny es esetlegesseg hataran mozgo szerep juthat a kornyezet altal meghatarozott sokfele parameternek, amelyek sokszor alapvetoen modosithatjak a kiragadott reszrendszer viselkedeset.
