This article explores links between the modern theory of rational choice and ethics. Ethics allows us to answer an unsolved question in modern decision theory: the structuring problem in decisions. Such a problem cannot be solved coming from the principle of expected utility. This principle can solve the problem of ‚choosing’ among given alternatives, but does not establish which alternatives should be taken into account in decision. In order to understand the structuring problem, the act of ‚choosing’ has to be (...) completed with three human acts: operating, predicting and evaluating. At the same time, the subjective criteria of rational choice – probability and utility – have to be completed with three objective criteria: efficiency, truth and goodness. Utility is a subjective value of an alternative considered in relation to another. Efficiency, truth and goodness are objective qualities of the joint alternatives in relation to the reality: the real operating possibilities of the agent, the real possibilities of his environment and the true good produced. So, the rule that guarantees a decision to be optimal would be: “do that which most certainly maximises our preferences, according to real operative resources, true knowledge and the right will”. However, this rule cannot be applied without the development of virtues, which could be seen as the main moral competences in decision-making. (shrink)

This article is a conceptual contribution on how to make human habitat more sustainable. Taking Heidegger’s conception of “dwelling” as a starting point, a new form of understanding the organization of the city as a human habitat is proposed. It is argued that human habitat is today in crisis and that such crisis has its roots in a spatial understanding of human dwelling, disregarding its temporal-historical dimension. For long time, the city has been considered as a physical “place” and its (...) organization—the urban planning—has been addressed in terms of “locating”. Many of the challenges in organizing habitat are the result of reducing the organization of the city to the organization of physical space. One of these is the conflict between preservation and development, a central issue in approaching sustainability. The aim of this article is to propose a new perspective on the organization of human dwelling, which overcomes the spatial-based conception of habitat and involves its temporal dimension. The meaning of human “habitat” as a historical process for developing “habits” will be recovered, and the implications for organization of the city considered. Human habitat is above all an ethical space, constituted in a spatial–temporal process of developing learning and capabilities. This habitat can be shared and developed infinitely so that a pathway is opened for overcoming the logic of competition and the conflict between sustainability and development. Finally, three forms of the human habitat as an “ethical space” are proposed. (shrink)

Desde la actual teoría general de la acción se han levantado objeciones contra la validez como saber transcendental de la critica de la razón práctica. Se la acusa de haber deducido la libertad del "faktum" moral en vez de deducir la moralidad de una libertad moralmente neutra y transcendentalmente ya asentada en el desarrollo critico teórico. Un estudio atento a la obra revela, sin embargo, que en ella no se abandona la "reflexión" crítica y es justamente por ello que la (...) moralidad puede entenderse como la doctrina transcendental de la libertad.

There is both individual and collective widespread concern in society about the impact of human activity and the effects of our decisions on the physical and social environment. This concern is included within the idea of sustainability. The meaning of the concept is still ambiguous and its practical effectiveness disputed. Like many other authors, this article uses as a starting point the definition proposed by the World Commission on Environment and Development, considering it to be a proposal for changing the (...) assessment of the effects of decisions, from at least two perspectives: what effects we should consider and how we should assess them. Based on this double perspective, sustainability is explored as a method for decision-making which both expands the assessment of the consequences, and also provides an objective criterion for such assessment. It will be argued that the idea of sustainability, seen from this perspective, brings to decision-making two qualities which had been partially lost: realism and impartiality. In turn, the criteria for realism and impartiality in decision-making can be used to identify the limitations of some partial approaches to sustainability, which suffer from insufficient realism, insufficient impartiality or both phenomena at once. The article concludes by demonstrating how realism and impartiality provide the basis for a new form of sustainable decision-making, which is dependent on the development of two moral virtues, prudence and benevolence, and which brings practical effectiveness and ethical sense to the concept of sustainability.

This article is a reflection on human habitat taking-off from a sentence by Millán Puelles: "Animals do not have problems with shelter, human beings do". A manner of overcoming the "philosophy of uprootment", apparently supported by the crisis of the city, is proposed. Such a crisis responds to two errors latent in the conception of human space. The first one is to be found in the notion of space in use; the second, in the wrong usage of the means-end model (...) in the relationship between spatial organization and human habitat. The solution to such a crisis lies in the recognition that spatial organization (habitat) above all consists in the construction of modes of living. (shrink)
