Cette recherche se propose d'analyser ce que nous appelons un « dispositif d'évaluation stoïcien ». Par « dispositif » nous faisons référence à un ensemble d'éléments qui interagissent entre eux d'une certaine manière, qui répondent à un enjeu et qui entrent en relation et en concurrence avec d'autres formations similaires ou pas. Parler de « dispositif d'évaluation » renvoie aussi bien à des processus psychiques, qu'aux éventuels critères auxquels satisfait ou doit satisfaire ce processus – une certaine distribution de la valeur – à l'enjeu qui lui est assigné et aux éventuels effets collatéraux. Valeur et jugement de valeur ne sont que les éléments d'un ensemble qui les englobe et se caractérise par les modalités de leur articulation. Reconstruire un « dispositif d'évaluation » stoïcien a pour enjeu de rendre compte de la manière dont les stoïciens conçoivent la discrimination « naturelle » de son environnement par le vivant humain et la portée de ce processus. Et par « naturelle », on comprendra « optimale » et « correcte » et non pas factuelle. Le dispositif d'évaluation doit en effet être compris comme l'expression du développement naturel, c'est à dire optimal et non pas effectif, de la pratique d'évaluation telle que les stoïciens la conçoivent, ce qui implique de ne pas confondre naturel et habituel, naturel et effectif. On voit d'emblée que la possibilité d'un dysfonctionnement n'est pas exclue. Réciproquement, le « dispositif d'évaluation » émerge au sens strict dans la reformulation prescriptive d'une pratique d'évaluation naturelle, c'est-à-dire optimale. / This research intends to analyse what we call a " Stoic device of evaluation ". By "device" we make reference to a set of elements which interact between themselves in a certain way, which answer a stake and which have relations and compete with the other similar formations or not. To talk about " device of evaluation " refers to psychic processes, as well as to possible criteria which this process satisfies or has to satisfy – a certain distribution of the value – to the stake which is assigned to him and to the possible collateral effects. Value and value judgment are only the elements of a set it includes them and is characterized by the modalities of their articulation. To reconstruct a " Stoic device of evaluation " has for stake to report the way the Stoics conceive the "natural" discrimination of its environment by human being and the impact of this process. And by "natural", we shall understand "optimal " and " correct" and not actual. The device of evaluation must be indeed included as the expression of the natural, that is optimal development of the practice of evaluation such as the Stoics conceive it, what involves not to confuse natural and usual, natural and actual. We see at once that the possibility of a dysfunction is not excluded. Mutually, the " device of evaluation " emerge in the strict sense in the prescriptive reformulation of a practice of natural, that is optimal evaluation.

Large institutional actors in the financial arena are moving their capital in a sustainable direction. This implies a change of the institutional norms and rules regarding sustainable investing. One of the problematic aspects of sustainable investing is how investors use different strategies to influence their holdings and what implications this choice might have on a sector level. The purpose of this paper is to empirically examine how the strategies from institutional investors are an expression of the current norms and rules in the field of sustainable investing. It also intends to illustrate how institutional pressures influence the strategies of investors and their holdings. By interviewing respondents from eleven institutional investors, we present data regarding norms and rules for sustainable investing and the consequences of the investor’s strategies. Our findings indicate there has been an immense increase in demand for sustainable products in recent years, resulting in institutional pressures that have influenced both the investors and their holdings. This exposes the field to selection processes which may force organizations to the point of adapt or die. Finally, our conclusion provides practical implications on what role institutional investors have in the quest for sustainable development.
