Recently, Bourne constructed a system of three-valued logic that he supposed to replace Łukasiewicz’s three-valued logic in view of the problems of future contingents. In this paper, I will show first that Bourne’s system makes no improvement to Łukasiewicz’s system. However, finding some good motivations and lessons in his attempt, next I will suggest a better way of achieving his original goal in some sense. The crucial part of my way lies in reconsidering the significance of the intermediate truth-value so (...) as to reconstruct Łukasiewicz’s three-valued logic as a kind of extensional modal logic based on partial logic.

Firstly I define a hole as a dependent matter-less endurant, which is a little modification of Casati and Varzi’s definition. Adopting this definition, holes seem to invite three problems about causation: (1)causal closure, (2)ungrounded disposition and (3)causal overdetermination. I will defend my definition against all these problems by showing that holes are limiting cases of physical endurants rather than their opposition and that they have causal powers in a broad sense.

Simple partial logic (=SPL) is, broadly speaking, an extensional logic which allows for the truth-value gap. First I give a system of propositional SPL by partializing classical logic, as well as extending it with several non-classical truth-functional operators. Second I show a way based on SPL to construct a system of tensed ontology, by representing tensed statements as two kinds of necessary statements in a linear model that consists of the present and future worlds. Finally I compare that way with (...) other two ways based on Łukasiewicz’s three-valued logic and branching temporal logic. (shrink)

M. Johnston proposed an adverbialist solution to the problem of intrinsic change of enduring things. D. Lewis interpreted it as a way of tensing the copula. In his view, it has the defect of replacing having a property simpliciter by standing in a triadic relation to a property and a time, and so is threatened by Bradley’s Regress. I agree with Lewis on requiring having a property to be non-relational, while I disagree with him on restricting it to having simpliciter. (...) I tense the copula non-relationally and yet more seriously than Johnston, by characterizing tense as a copulative de re modality concerning endurance, which I relate to R. Taylor’s ‘pure becoming’. I will show that my way gives a better solution to the problem of intrinsic change than those by other endurantists, because of its close connection to an account of tense, endurance and becoming.

This paper addresses some problems related to the relation of truthmaking, especially those concerning its necessity, adopting an essentialist point of view and focusing on the nature of truthbearers. According to the orthodox view in truthmaker theory, the relation of truthmaking is necessary in some sense. Thus, an important question involves how the relation of truthmaking is made necessary. I adopt a version of Jonathan Lowe’s essentialist approach to this question. However, contra Lowe, I take token acts of predication as (...) the primary truthbearers. This is Peter Hanks’ view in the philosophy of language. I shall argue that some problems with the essentialist approach can be solved by taking the nature of token acts of predication to be the source of necessity in truthmaking. At the end of this paper, I shall also briefly outline two general consequences related to truthmaking that I suppose this move about truthbearers should have. (shrink)

This is a review essay on Daisuke Kachi’s recent book, Agents: Contemporary Substance Ontology (sic. Shunjusha, 2018). The book develops and partially defends an ontology that takes the category of substance as the most fundamental one. The author provides in it a new perspective on substance, which consists in characterizing substances as bearers of what he calls “substance modalities” (of which there are four kinds, that stem from the factors of essence, power, past persistence, and future persistence respectively). The (...) first part of this review essay gives an extended overview of Kachi’s book while the second discusses some problems it may face. (shrink)

Chapter headings are: The law - an objective reality. The dogma of the law. The drama of scholarship. Searching. "The entire" substance of the law. Juridical constructs. The logic of laws. The secret of the law. Law - the highest purpose. Law in the life and fate of mankind.

Gottfried Martin has recently reminded us of a useful distinction between two possible ways of doing metaphysics. We may proceed by framing a “theory of principles” or by proposing a “theory of being”. Aristotle explicitly formulates both possibilities as the task of metaphysics, formulating a theory of principles in his doctrine of the four types of causal explanation in the first book of the Metaphysics, while exploring the theory of being in a number of other passages, such as Book I, (...) chapters 6 and 9; Book X, chapter 2; and Book XIII. These passages do not elaborate principles whereby we can analyze the structure of certain entities, be they causes, substances or forms, but rather concern themselves with the ontological status of these entities—in what sense can they be said to be? In Plato this distinction is more implicit, but we may contrast the theory of forms developed in the Phaedo and the Republic with the subsequent probing investigation of the being of these forms in the Parmenides and the Sophist. Kant “explicitly claims to have discovered and presented a complete and necessary system of the basic concepts and principles. The proof of the completeness and necessity of this system is the aim of the middle part of the Critique of Pure Reason, the Transcendental Analytic.” Yet. (shrink)

The purpose of the present study was to address the shortcomings of Cronbach’s alpha concerning the semantic overlap between items. Using an example from a motivational measure, the correction of Cronbach’s alpha was applied by partialing out the effects due to conceptual overlap. The significance of Cronbach’s alpha was tested using simulated random data derived from the measure and by estimating the confidence intervals with known and unknown distributions. The results indicated that the uncorrected conceptual overlap coefficient alpha was equal (...) to 0.89 and 0.66 following the correction. After simulating the corrected statistical results, the distribution of alpha with random numbers had an estimate of 95%, equal to 0.41. The lower bound of the corrected alpha distribution was equal to 0.41, suggesting that the corrected alpha could easily belong to the distribution of alpha developed from simulated random numbers. Thus, the semantic overlap between items on a measure represents a significant threat to the validity of the alpha coefficient. (shrink)

Part of the accepted scholarly lore about Kierkegaard is that he holds that “existence”—human existence—and “the System” are mutually incompatible. For Kierkegaard, human being cannot be understood in terms of a nice, neat, complete systematic package; he shows, on this view, that the Hegelian attempt to grasp all of reality in terms of a philosophical system will always fail to grasp the reality of at least one thing: the concrete, living, existing individual human being.

This is the first scholarly study of Atlas Shrugged, covering in detail the historical, literary, and philosophical aspects of Ayn Rand's magnum opus. Topics explored in depth include the history behind the novel's creation, publication, and reception; its nature as a romantic novel; and its presentation of a radical new philosophy.

William James is famous for his investigations of the “Varieties of Religious Experience” in which people encounter (what they take to be) the divine. But in his essay, “On a Certain Blindness in Human Beings,” his interest is in our experiences, not of anything purportedly supernatural, but of one another. He thinks we need to cultivate the capacity to apprehend the intrinsic value of others, even and especially of strangers. We do so in experiences of the wonder and beauty of (...) our fellow citizens, and of our harmony with them. Democratic societies require a sense of attraction to one another’s form of life if they are to inspire shared commitments to public goods. Whereas we shouldn’t reject the political significance of aversion, contestation, and dissonance, these negative attitudes do not suffice. Sustaining democratic engagement requires attractive attitudes, and among these are the wonder, beauty, and harmony that James promotes. (shrink)

The biblical image of Wisdom as the power who “orders all things well” in nature and in human life can be read in the light of contemporary information theory. Some current scientific speculation offers an interpretation of reality as a vast information‐processing system, in which informational situations are continuously transformed through algorithmic operations. This interpretation finds a metaphysical counterpart in the distinction between “nature natured” and “nature naturing” in the philosophical theology of Samuel Taylor Coleridge. This confluence of religious, metaphysical, (...) and scientific imagery suggests a picture of the world in which the processes of “nature naturing,”“human humaning,” and “God Godding” inform and recur in each other.

Popper proposes a technical concept of 'verisimilitude' as a test of the progressiveness of scientific theories. The paper attempts to show its uselessness and inapplicability on mathematical and practical grounds, As well as raising doubts about the value of any such attempt to give a mechanical test of scientific progress.
