Luciano Floridi’s informational structural realism takes a constructionist attitude towards the problems of epistemology and metaphysics, but the question of the nature of the semantical component of his view remains vexing. In this paper, I propose to dispense with the semantical component of ISR completely. I outline a Syntactical version of ISR. The unified entropy-based framework of information has been adopted as the groundwork of SISR. To establish its realist component, SISR should be able to dissolve the latching problem. We have to be able to account for the informational structures–reality relationship in the absence of the standard semantical resources. The paper offers a pragmatic solution to the latching problem. I also take pains to account for the naturalistic plausibility of this solution by grounding it in the recent computational neuroscience of the predictive coding and the free energy principle.

The relationship between Carnap’s Logical Syntax of Language and Wittgenstein’s Tractatus Logico-Philosophicus has been interpreted in several ways during past decades. One of the interpretations has gained keen advocates among Carnap scholars. It was originally provoked by what Caranp said in LSL, and it consists of two parts. First, it indicates that in TLP the possibility of speaking about the logical form of a language within the same language had been foresworn by Wittgenstein, but Carnap proved him wrong by producing a book written exactly in the manner which had been proscribed by Wittgenstein. This is the debate about the possibility of speaking about logical form. Second, Wittgenstein’s dogmatism with regard to the existence of a unique correct grammar at the foundation of the language has been contrasted with Carnap’s open-mindedness in conceiving a boundless ocean of possibilities for constructing logical systems. Interestingly enough, Wittgenstein rambled with rage in reaction to Carnap’s view about the LSL-TLP relationship. But unlike Carnap’s view, which led to a dominant interpretation of the relationship, Wittgenstein’s testimony about the case has been strangely ignored in the history of analytic philosophy. In this paper, I try to make an inquiry about the grounds for Wittgenstein’s dissatisfaction with the Carnapian reading of the LSL-TLP relationship. I will show that Wittgenstein was not totally unfair in his judgment, and that some salient aspects of LSL could be best understood in the light, or rather the gloom, of TLP, and bear a significant resemblance to it. This, however, does not need to diminish the logical and historical significance of LSL.

Building upon Brentano’s Psychology from an empirical standpoint. Routledge, London, [1874] Brentano 1995) reintroduction of the concept of intentionality to the contemporary philosophy, Tim Crane has famously presented the intentionality as the mark of the mental. Accordingly, the problem of “intentional existence” has resurfaced in Crane’s revival of the Brentanoian theme. Here, I revise Crane’s construal of Brentano’s notion of intentional inexistence and reinterpret it in terms of a moderate version of relationalism. My relationalist theory of intentionality is inspired by what goes by the name of Noneliminativist Structural Realism in the contemporary philosophy of science. NSR allows for a robust realist interpretation of the role of scientific models. The underlying insight of the paper is that it is best to be realist about the structure of the intentionality, which is the common element of the diverse theories of intentional objects. The Outcome is Structural Realist theory of Intentionality. I argue that SRI is not liable to the notorious objection of the impossibility of relata-less relations. I conclude that SRI fulfils the goal of robust psychological realism more economically and straightforwardly than Crane’s application of the notion of models.

The paper surveys Floridi’s attempt for laying down informational structural realism. After considering a number of reactions to the pars destruens of Floridi’s attack on the digital ontology, I show that Floridi’s enterprise for enriching the ISR by borrowing elements from the ontic form of structural realism is blighted by a haunting inconsistency. ISR has been originally developed by Floridi as a restricted and level dependent form of structural realism which remains mainly bonded within the borders of a Kantian perspective. I argue that this perspective doesn’t mesh nicely with the ontic interpretation that Floridi attached to the ISR. I substantiate this claim through the assessment of Floridi’s strategy for reconciling the epistemic and ontic forms of the SR, as well as by close examination of his use of method of levels of abstraction and his notion of semantic information. My proposal is that the ISR could be defended best against the mentioned and similar objections by being interpreted as an extension of the epistemic SR.

In this paper, inspired by the late twentieth century developments in philosophy of science, I propose an ontological scheme to accommodate the scientifically-informed anti-substantivalist views of the self. I call the position structural realist theory of the self. More specifically, I argue that SRS provides a middle ground for bringing a metaphysical reconciliation between the two recurring, and apparently competing forms of such anti-substantivalist views, i.e., eliminativism and pluralism. The notion of the structural self, as the underpinning pattern that is the subject of the ontological commitments in SRS, is not as cumbersome as the orthodox substantivalist notion, and yet accounts for the relation of the different aspects and elements of the self by integrating them structurally into a central unifying pattern of selfhood. I use the experimental studies of Northoff et al. about the processing of the self-related stimuli in the cortical midline structure of the brain, to argue that the underlying pattern of the selfhood could be sought at the level of information processing. I also add a programmatic suggestion about how the different situated, experiential and extended aspects of the selfhood could be structurally incorporated into this underlying pattern.

In this paper I am advocating a structuralist theory of mental representation. For a structuralist theory of mental representation to be defended satisfactorily, the naturalistic and causal constraints have to be satisfied first. The more intractable of the two, i.e., the naturalistic constraint, indicates that to account for the mental representation, we should not invoke “a full-blown interpreting mind”. So, the aim of the paper is to show how the naturalistic and causal constraints could be satisfied. It aims to offer a strategy for grounding the structure of the mental representations in nature. The strategy that I offer is inspired by Marcello Barbieri’s code model of biosemiotics.

The paper aims to provide a detailed assessment of Tim Crane’s recent invocation of the notion of scientific models in the way of dealing with the issue of the brain’s representational states. In this paper, I assess Crane’s proposal under a charitable and a less charitable reading. I argue that Crane’s use of scientific models is at best compatible with his expression of psychological realism. However, Crane’s use of model-based strategy by no means underlay, support, or strengthen his psychological realism. Rather, traditional reasons from the metaphysics of mind, acting quite separately from empirical scientific reasons, must be used to support this realism, and Crane has merely removed the threat posed to these metaphysical arguments by the existence of the so-called mereological fallacy in empirical neuroscience. Therefore, while he has saved the neuroscientific language from philosophical attack, he has perhaps even strengthened the divide between neuroscience and philosophy. I conclude the paper by outlining the sketch of a broadbrush scientifically informed strategy for defending psychological realism.

Can the abstract entities be designated? While the empiricists usually took the positive answer to this question as the first step toward Platonism, in his ``Empiricism, Semantics, and Ontology’’ [Carnap 1950], Carnap tried to make a reconciliation between the language referring to abstract entities on the one hand, and empiricism on the other. In this paper, firstly, I show that the ingenuity of Carnap’s approach notwithstanding, it is prone to criticism from different aspects. But I also show how, even without leaving the empiricist research program, the shortcomings could be amended. Following Carnap’s 1950 outset, and adding some apparently untasteful (Meinongian) ingredients, I will sketch a refined way for dealing with the problem of existence of abstract entities within the framework of the philosophy of empiricism.

Using the theory of definite descriptions, Russell and, following him, Quine masterfully challenged Meinong’s Theory of Objects (TO). In this paper, firstly I try to show that although the Russell-Quine’s interpretation of TO has been taken seriously even by many notable Neo-Meinongians and first-rate scholars, yet it is not the ultimately convincing reading of the Theory, at least not when we boil down the theory to Meinong’s primary motives and his essential arguments. Moreover, I show that a form of the indispensability argument is the backbone of Meinong’s theory. The argument is surprisingly akin to what Quine proposed for his realism with regard to the existence of mathematical entities. Consequently, I argue that mathematics plays an important role in Meinong’s argument and hence his overall theory. I believe that in this way the debate between Meinongian and Quinean can be directed to more compromising and fruitful grounds.
