In lieu of an abstract, here is a brief excerpt of the content:NECESSARY PROPOSITIONS AND THE SQUARE OF OPPOSITION MARK ROBERTS University of Rhode Island Kingston, Rhode Island IT IS COMMONPLACE to define contradictory, contrary, and subcontrary propositions in the following way: contradictory propositions cannot both be true and cannot both be false; contrary propositions cannot both be true but can both be false; and subcontrary propositions can both be true but cannot both be false. In his Introduction to Logic (...) 1 Irving Copi raises a problem with two of these definitions which he believes forces him to limit the range of propositions which can be used in the square of opposition. Since contrary propositions can both be false, but the falsity of a necessarily true proposition is not possible, a necessarily true proposition has no contrary. Therefore, only contingent propositions can be contraries. Subcontrary propositions can both be true, but the truth of a necessarily false proposition is not possible.2 This problem is rarely raised in other logic texts, but, it is interesting to note, it is mentioned by a number of neoscholastic philosophers, for example, P. Nicholas Russo,3 Rev. H. Grenier,4 1 Irving M. Copi, Introduction to Logic (New York: Macmillan, 1986), pp. 178-179. Copi first introduced this problem in the fifth edition of his work on the basis of an article by David H. Sanford entitled " Contraries and Subcontraries,'' Nous 2 (1968) : 95-96. Sanford argues that the most reasonable way to resolve the problem of necessary propositions is to assume that contingent propositions comprise the square of opposition. 2 Copi, pp. 178-179. 8 Nicholas Russo, Summa Philosophica (Boston: Apud Marlier et Socios, 1[;85), p. 23. 4 Henri Grenier, Thomistic Philosophy, Vol. I (Charlottetown, Canada: St. Dunstan's University, 1950), p. 69. 427 428 MARK ROBERTS G. Sanseverino,5 Jacques Maritain,6 F.-X. Maquart,7 P. Coffey,8 and others.9 (It is also mentioned by Bishop Whately.10 ) Each of these philosophers makes necessarily true or false propositions an exception to the definition of contrary and subcontrary propositions. The reason is they and Copi interpret the definitions of contrary and subcontrary propositions to mean that the falsity of each contrary proposition is possible and the truth of each subcontrary proposition is possible. It should be mentioned, however, that the position of the philosophers cited above is not entirely the same as Copi's. Copi reasons that these definitions imply that necessary propositions have no contrary or subcontrary. The other philosophers believe that necessary propositions can be contraries and subcontraries. Thus, in the case of necessary propositions contrary and subcontrary propositions are, instead, defined merely in terms of their quantity and quality, not by whether or not they can both be false or can both be true. In fact, Coffey and some of the other philosophers cited above assert that, when the propositions composing the square are necessary, one can infer the truth of the universal from the truth of 5 Gaietano Sanseverino, Philosophia Christiana, Vol. II (Neapoli: Vincentii Manfredi, 1862), pp. DCCXXXVIII ff. 6 J.

We are reviewing and summarizing evidence for the processes of acquisition of information outside of conscious awareness (processing information about covariations, nonconscious indirect and interactive inferences, self-perpetuation of procedural knowledge). A considerable amount of data indicates that as compared to consciously controlled cognition, the nonconscious information-acquisition processes are not only much faster but also structurally more sophisticated in the sense that they are capable of efficient processing of multidimensional and interactive relations between variables. Those mechanisms of nonconscious acquisition of information (...) provide a major channel for the development of procedural knowledge which is indispensable for such important aspects of cognitive functioning as encoding and interpretation of stimuli and the triggering emotional reactions.

Originally published in 1969. This book explains what is wrong with the traditional methodology of "inductive" reasoning and shows that the alternative scheme of reasoning associated with Whewell, Pierce and Popper can give the scientist a useful insight into the way he thinks.

In their introduction to this volume, Ram and Leake usefully distinguish between task goals and learning goals. Task goals are desired results or states in an external world, while learning goals are desired mental states that a learner seeks to acquire as part of the accomplishment of task goals. We agree with the fundamental claim that learning is an active and strategic process that takes place in the context of tasks and goals (see also Holland, Holyoak, Nisbett, and Thagard, 1986). (...) But there are important questions about the nature of goals that have rarely been addressed. First, how can a cognitive system deal with incompatible task goals? Someone may want both to get lots of research done and to relax and have fun with his or her friends. Learning how to accomplish both these tasks will take place in the context of goals that cannot be fully realized together. Second, how are goals chosen in the first place and why are some goals judged to be more important than others? People do not simply come equipped with goals and priorities: we sometimes have to learn what is important to us by adjusting the importance of goals in the context of other compatible and incompatible goals. This paper presents a theory and a computational model of how goals can be adopted or rejected in the context of decision making. In contrast to classical decision theory, it views decision making as a process not only of choosing actions but also of evaluating goals. Our theory can therefore be construed as concerned with the goal-directed learning of goals. (shrink)

1. _The project_ Over the last two and a half centuries three main strands of opinion can be discerned in philosophers.

In this paper, I argue that AI literacy should be added to the list of primary goods developed by political philosopher John Rawls. Primary goods are the necessary resources all citizens need to exercise their two moral powers, namely their sense of justice and their sense of the good. These goods are advantageous for citizens since without them citizens will not be able to fully develop their moral powers. I claim the lack of AI literacy impacts citizens’ ability to exercise (...) their sense of justice and their sense of the good. Without citizens having the ability to understand how AI technology works – including being aware of the social and political implications and the limits and possibilities of this technology broadly speaking – this could impact their ability to participate in a free, equal and fair society and their ability to carry out their conception of the good. Thus this paper is a call for AI literacy to be regarded as a basic good in a liberal constitutional democracy in order for citizens to be able to exercise their freedom and equality. (shrink)

Science as a social institution today is experiencing a phase of profound transformation. Objects, methods, research technological tools, methods of institutional communication and mechanisms for commercializing new knowledge are changing. The creation of new interdisciplinary communication platforms is more relevant today than ever before. This review pro[1]vides key information about the First Conference «Mind, Body, Intelligence, Language in the Age of Cognitive Technologies». The organizers created an event that brought together IT developers, academic researchers, and business representatives.

This article examines some of S. Lem’s statements about his philosophical and worldview positions regarding the mysterious nature of language and the linguistic sign, the connection between language, mind and reality. The main goal of the paper is to understand what texts on the philosophy of language the Polish thinker read and what attitude he has formed towards them. Lem is the follower of an analytical intellectual culture that focuses on the naturalistic worldview and the consequences of the “linguistic turn” (...) in Western philosophy. For Lem, language is not only an interesting philosophical object, but also a complex precise instrument of his own creative thinking. In this regard, the philosophy of language for a writer cannot be based only on logical-linguistic atomistic methodology. Lem seeks in his contemporary interdisciplinary methods ways to combine realistic and anti-realist positions. Many concepts, such as “the effect of semantic transparency”, “polymorphic language model”, “variation model” are quite correlated with modern theories of language and require additional philosophical comments.

I claim that the revisions John Rawls made to his theory of justice—as seen in his political conception of justice as fairness in the revised edition of Political Liberalism and Justice as Fairness: A Restatement—result in him being able to secure justice for all persons even in their private lives. Thus, I defend his theory against common communitarian and feminist criticisms, viz the lack of moral community and inability to secure justice for individuals in the private domain. I demonstrate that (...) justice is secured from the categorical requirement that all associational life and moral doctrines must adhere to the constraints of justice, by (what Rawls terms) the indirect application of the first principle of justice. The implications of and necessity for this indirect application are precisely what I interrogate in this thesis. I suggest that this indirect application requires unconditional acknowledgement and internalisation of the values of liberty and equality (political values of the first principle) into all aspects of civil society. I claim that Rawls realised this necessity for the congruence between the moral powers of persons, the spheres of society, and the right and the good and, as such, developed a complementary relation between these three features. Coherence between these three aspects is essential; without coherence, citizens would have a split moral personality, the public and the non-public spheres would be in conflict, and the political values and the moral doctrines of individuals would undermine one another. The significance of this strict coherence is that it can ensure the adequate development of individuals’ capacity for citizenship during the three stages of moral development. This results in citizens being able to form bonds of civic friendship necessary for justice as reciprocity to be realised. Thus, in this thesis, I position my argument against theorists such as Nancy Rosenblum, who argue for a more relaxed congruence between political institutions and civil society, as according to her illiberal forms of associational life can help form the necessary bonds of love and care needed for mutual cooperation in a liberal society. In opposition to this, I claim that strict congruence is necessary; without it, a stable liberal society is not possible as the citizens would not be able to able to respect one another on free, equal, and mutually beneficial terms. I rely on Hochschild’s sociological evidence to demonstrate that civic friendship has not been developed, due to a lack of reciprocity, impacting the negative development of one’s sense of justice. I then illustrate how this lack of reciprocity is amplified by digital and artificial intelligence (AI) technologies. The significance of this thesis is that I claim, firstly, Rawls’s last revisions and works before his death demonstrate that justice is a collective non-comprehensive good that results by constraining individuals’ associational life and their partial comprehensive doctrines to Rawlsian demands of justice. Thus, Rawls takes seriously the feminist and communitarian critiques he received. Secondly, I claim that this interpretation of Rawls’s theory of justice cannot be conceptualised in terms of a binary presentation of the priority of the right versus the good debate and, instead, I argue for a reconceptualisation of the priority of the right versus the good as ranges on a continuum of structural relations between the right and the good.

Open peer commentary on the article “Social Autopoiesis?” by Hugo Urrestarazu. Upshot: Hugo Urrestarazu’s social theoretical concept is reduced to the material reality. These suggestions exclude the essential constructivist character of the social and thereby important social phenomena by definition. The systems theoretical approach by Niklas Luhmann offers an adequate alternative.
