The original Brouwerian counter examples were algorithmic in nature; after the introduction of choice sequences, Brouwer devised a version which did not depend on algorithms. This is the origin of the creating subject technique. The method allowed stronger refutations of classical principles. Here it is used to show that negative dense subsets of the continuum are indecomposable.  相似文献

Conclusion In Section IV above we start with texts whose prima facie import speaks so strongly for the Identity Thesis that any interpretation which stops short of it looks like a shabby, timorous, thesis-saving move. What else could Socrates mean when he declares with such conviction that no evil can come to a good man (T19), that his prosecutors could not harm him (T16(a)), that if a man has not been made more unjust he has not been harmed (T20), that all of happiness is in culture and justice (T16(a)), that living well is the same as living justly (T15)? But then doubts begin to creep in. Recalling that inflation of the quantifier is normal and innocuous in common speech (that job means everything to him, he'll do anything to get it, will stick at nothing) we ask if there is really no chance at all that no evil in T19, not harmed in T20 might be meant in the same way? The shift from no harm at T16(a) to no great harm at T16(b), once noticed, strengthens the doubt. It gets further impetus in T21(b) when to explain how all of happiness is in culture and justice he depicts a relation (that recurs more elaborately in T22) which, though still enormously strong, is not quite as strong as would be required by identity. The doubt seeps into T15 when we note that current usage did allow just that relation as a respectable use of the same.At that point we begin to wonder if resort to the Identity Thesis might not be just a first approximation to a subtler, more finely nuanced, doctrine which would give Socrates as sound a foundation for what we know he wants to maintain at all costs - the Sovereignty of Virtue - without obliterating the eudaemonic value of everything else in his world. We cast about for a credible model of such a relation of virtue to happiness and hit on that multicomponent pattern sketched on p. 9 above. We ascertain that this will afford a comprehensively coherent eudaemonist theory of rational action, while its rival would not, and will fit perfectly a flock of texts in Section V which the latter will not fit at all. Are we not entitled to conclude that this is our best guide to the true relation of virtue to happiness in Socrates' thought - the one for which he would have declared if he had formulated explicitly those two alternative theses and made a reasoned choice between them?The Socrates of this paper is the protagonist of Plato's earlier dialogues. I list these (by self-explanatory abbreviations), borrowed from T. Irwin, Plato's Moral Theory [1974] (hereafter PMT): Ap., Ch., Cr., Eud., Eu., G., HMa., HMi, Ion, La., Ly., Pr., R., I. I assume, but shall not argue here, that in this segment of his corpus, Plato aims to recreate the doctrines and arguments of his teacher in dramatic scenes, all of which (except for the Ap.) may be, and most of which undoubtedly are, fictional; I shall be referring these works, under this proviso, as Plato's Socratic dialogues. (I did not include the Menexenus in the above list, since the parody of a funeral oration in this dialogue is implicitly dissociated from Socrates.)  相似文献

In their book Entailment, Anderson and Belnap investigate the consequences of defining Lp (it is necessary that p) in system E as (pp)p. Since not all theorems are equivalent in E, this raises the question of whether there are reasonable alternative definitions of necessity in E. In this paper, it is shown that a definition of necessity in E satisfies the conditions { E Lpp, EL(pq)(LpLq), E pLp} if and only if its has the form C 1.C2 .... Cnp, where each C iis equivalent in E to either pp or ((pp)p)p.  相似文献

Re-emergent scientific atheism bears the marks of its historical origins in the efforts of Bon-Bruevi and Jaroslavskij. The disciples of the Lenin generation use their fathers somewhat as second-level classics.  相似文献

Group beliefs   总被引:3,自引:0,他引:3  
Raimo Tuomela 《Synthese》1992,91(3):285-318
It is argued in this paper that there can be both normative and nonnormative, merely factual group beliefs. The former involve the whole social group in question, while the latter only relate to the distributions of personal beliefs within the group. The paper develops a detailed theory, called the positional account of group beliefs, to explicate normative, group-involving group beliefs. Normative group beliefs are characterized within this approach in terms of joint acceptances of views by the group members — or their representatives — acting in their right positions and tasks, and in a sense creating group commitments for all the members to accept (and keep accepting) the view in question. Also aggregate accounts of group belief are considered in the paper, especially the shared we-belief approach. Such aggregate accounts purport to account for merely factual group beliefs.I wish to thank Kaarlo Miller and Philip Pettit for critical comments.  相似文献

Two studies showed that adults' responses to questions involving the term or varied markedly depending upon the type of question presented. When presented with various objects (A's and B's) and asked to circle all things which are A or B subjects tended to circle A's as well as B's, whereas when asked to circle all the A's or B's subjects showed a relatively stronger tendency to circle one or the other. Moreover the nature of the sets of objects (As and Bs) influenced behavior as well. There was also evidence that the effects due to question wording or set type transferred.  相似文献

This paper points out the way in which educational and communicative action (Habermas) are to be related. It is shown that earlier attempts to put Habermas ideas to use have led to a dead end because they do not realize clearly that the new basic notion introduced by Habermas, namely communicative action, is the expression of a communicative turn. It is argued that Habermas' concept expresses a radical new attempt to grasp the intersubjective character of social action. Next implications of this communicative turn for the concept of education as a social praxis are indicated. Education can be conceived of as a praxis responding to the vulnerability of a communicative self.  相似文献

We generalize a well-knownSmullyan's result, by showing that any two sets of the kindC a = {x/ xa} andC b = {x/ xb} are effectively inseparable (if I b). Then we investigate logical and recursive consequences of this fact (see Introduction).  相似文献

In order responsibly to decide whether there ought to be an international legal right of secession, I believe we need an account of the morality of secession. I propose that territorial and political societies have a moral right to secede, and on that basis I propose a regime designed to give such groups an international legal right to secede. This regime would create a procedure that could be followed by groups desiring to secede or by states desiring to resolve the issue of secession. It would give territorial political societies a legally recognized liberty to conduct a plebiscite on secession, and, assuming such a plebiscite is won by the secessionist side, a qualified right in international law to create a state without interference. Alan Buchanan has argued that proposals of this sort would create perverse incentives. I argue that there is no good reason to believe this. The point is to allow the legal regulation of secession in cases where there are active secessionist movements with legitimate moral claims, and to attempt to dampen the desire for secession in cases where secessionist sentiment is not well grounded in social and geographic reality.  相似文献

This paper examines the question of whether there are effects of prosody on the syntactic parsing of temporarily ambiguous sentences containing complement verbs. It reports the results of five experiments employing cross-modal response tasks where the visually presented target word was either an appropriate or an inappropriate continuation in terms of the prosodic form of the preceeding auditory sentence fragment. Two experiments employing cross-modal naming only showed indications of sensitivity to syntactic and appropriateness manipulations when coupled with a simultaneous appropriateness judgment task. In contrast, the experiments employing cross-modal lexical decision showed greater sensitivity to syntactic and appropriateness effects. However, while the results from these studies replicated our earlier auditory parsing results and provided support for the suggestion that there are differences in visual and auditory parsing processes and for a constituent-based, minimal commitment type auditory parser, none of the studies demonstrated an effect of prosodic form on the parsing process.  相似文献

Mylan Engels paper (2004) is divided into two parts: a negative part, criticizing the costs of contextualism and a constructive part proposing a noncontextualist resolution of the skeptical problem. I will only address the constructive part here. The constructive part is composed of three elements: (i) a reconstruction or reformulation of the original skeptical argument, which draws on the notion of epistemic possibility (e-possibility), (ii) a distinction between two senses of knowledge (and two corresponding kinds of e-possibility): fallibilistic and infallibilistic, and (iii) an argument which tries to hoist the skeptic by their own petard, namely the closure principle (CP). As I will argue, there are two ways to understand Engels anti-skeptical argument. Only in one interpretation does the argument depend on the proposed reconstruction of the skeptical argument in terms of e-possibility. But this version of the argument is unsound. More importantly, the skeptic has a strong prima facie objection at her disposal, which applies to both interpretations of the argument. If this objection is valid, Engels argument does not hold. But once it is invalidated, his argument is superfluous.  相似文献

This article aims at elucidating the logic of Arist. SE 22, 178b36–179a10 and, in particular, of the sophism labelled "Third Man" discussed in it. I suggest that neither the sophistic Walking Man argument, proposed by ancient commentators, nor the Aristotelian Third Man of the , suggested by modern interpreters, can be identified with the fallacious argument Aristotle presents and solves in the passage. I propose an alternative reconstruction of the Third Man sophism and argue that an explanation of the lines regarding the identity of Coriscus and Coriscus the musician (178b39–179a3) is indispensable for its correct understanding, since they hint at another sophism in some important aspects analogous. Finally, I show that two contradictions concerning spotted by scholars in the passage are only apparent and can be dissolved once the assumption that the anti-Platonic Third Man argument is at stake here is discarded, and once the passage is read in the light of its agonistic context.  相似文献

The father of personal prehistory serves as the earliest and most enduring representation of God. This sexually undifferentiated father is identified by Freud as both parents and the flow of feeling between them. Kristeva elaborates to say that the first father creates the foundation for the infant's sexual differentiation, that is, a primary narcissistic screen. When parental flow of feeling provides inadequate compensation for the loss of oneness with Mother, the infant intrapsychically constructs its own foundation, an Other that has both parents' ideal qualities, a God who is a psychologically necessary He. Consequently, females have different experiences than males as they form and relate to their self- and God-representations.  相似文献

During the First World Family Therapy Congress, Dublin, 1989, the author was the only women on a six member panel discussing The New Paradigm. This article re-presents her attempt to remember women and other invalid subjects, (e.g. those in poverty) in what was imagined would be an otherwise male oriented discourse. Until recently, within family therapy, the contrary and negatory experiences of women in families and society gained little recognition. This article joins others in adding herstory to history.She is in private practice at Vico Consultation Centre.The author acknowledges her team, Nollaig Byrne and Philip Kearney; and her sister witches (The Women in Therapy Chapter), Kay Gilliland, Bernadette O'Sullivan, Mia Van Doorslaer, and Jane Williams for their valued help and comments on this paper.  相似文献

Both arguments are based on the breakdown of normal criteria of identity in certain science-fictional circumstances. In one case, normal criteria would support the identity of person A with each of two other persons, B and C; and it is argued that, in the imagined circumstances, A=B and A=C have no truth value. In the other, a series or spectrum of cases is tailored to a sorites argument. At one end of the spectrum, persons A and B are such that A=B is clearly true; at the other end, A and B are such that the identity is clearly false. In between, normal criteria of identity leave the truth or falsehood of A=B undecided, and it is argued that in these circumstances A=B has no truth value.These arguments are to be understood counterfactually. My claim is that, so understood, neither establishes its conclusion. The first involves a pair of counterfactual situations that are equally possible or tied. If A=B and A=C have no truth value, a counterfactual conditional with one of them as consequent and an antecedent that is true in circumstances in which either is true should have no truth value. Intuitively, however, any such counterfactual is false. The second argument can be seen to invite an analogous response. If this is right, however, there is an important disanalogy between this and the classical paradox of the heap. If the disanalogy is only apparent, the argument shows at most that the existence of persons can be indeterminate.  相似文献

In "Doing Well Enough: Toward a Logic for Common Sense Morality", Paul McNamara sets out a semantics for a deontic logic which contains the operator It is supererogatory that. As well as having a binary accessibility relation on worlds, that semantics contains a relative ordering relation, . For worlds u, v and w, we say that u w v when v is at least as good as u according to the standards of w. In this paper we axiomatize logics complete over three versions of the semantics. We call the strongest of these logics DWE for Doing Well Enough.  相似文献

Conclusion It follows from the proved theorems that ifM =Q, (whereQ={0,q 1,q 2,...,q }) is a machine of the classM F then there exist machinesM i such thatM i(1,c)=M (q i,c) andQ i={0, 1, 2, ..., +1} (i=1, 2, ..., ).And thus, if the way in which to an initial function of content of memorycC a machine assigns a final onecC is regarded as the only essential property of the machine then we can deal with the machines of the formM ={0, 1, 2, ..., }, and processes (t) (wheret=1,c,cC) only.Such approach can simplify the problem of defining particular machines of the classM F , composing and simplifying them.Allatum est die 19 Januarii 1970  相似文献

The most difficult problem that Leniewski came across in constructing his system of the foundations of mathematics was the problem of defining definitions, as he used to put it. He solved it to his satisfaction only when he had completed the formalization of his protothetic and ontology. By formalization of a deductive system one ought to understand in this context the statement, as precise and unambiguous as possible, of the conditions an expression has to satisfy if it is added to the system as a new thesis. Now, some protothetical theses, and some ontological ones, included in the respective systems, happen to be definitions. In the present essay I employ Leniewski's method of terminological explanations for the purpose of formalizing ukasiewicz's system of implicational calculus of propositions, which system, without having recourse to quantification, I first extended some time ago into a functionally complete system. This I achieved by allowing for a rule of implicational definitions, which enabled me to define any propositionforming functor for any finite number of propositional arguments.To the memory of Jerzy Supecki  相似文献

The set (X, J) of fuzzy subsetsf:XJ of a setX can be equipped with a structure of -valued ukasiewicz-Moisil algebra, where is the order type of the totally ordered setJ. Conversely, every ukasiewicz-Moisil algebra — and in particular every Post algebra — is isomorphic to a subalgebra of an algebra of the form (X, J), whereJ has an order type . The first result of this paper is a characterization of those -valued ukasiewicz-Moisil algebras which are isomorphic to an algebra of the form (X, J) (Theorem 1). Then we prove that (X, J) is a Post algebra if and only if the setJ is dually well-ordered (Theorem 2) and we give a characterization of those -valued Post algebras with are isomorphic to an algebra of the form (X, J) (Theorem 3 and Proposition 2).  相似文献
